How to migrate from the Payment Intent API to the Orders API

The Orders API unifies in-person payment processing for Mercado Pago Point, providing standardized endpoints, a more complete status model, and new native capabilities that did not exist in the Payment Intent API. In addition, all new Mercado Pago features will be developed on the Orders API.

Migrating your Mercado Pago Point integration from the Payment Intent API to the Orders API involves updating endpoints and request fields, adapting the status model, and leveraging new native resources, such as the dedicated refund endpoint. The migration does not change the business flow: the terminal continues receiving orders created by the backend and processing payments autonomously.

Read on to learn how to complete this migration.

Map the endpoint changes

Before starting the migration steps, see the table below for an overview of all endpoint changes. In the Payment Intent API, each operation had its own URL structure with the device identifier in the path. The Orders API consolidates these operations into standardized endpoints and removes the {deviceid} from the path in all operations.

Operation	Payment Intent API	Orders API
List terminals	GET /point/integration-api/devicesAPI	GET /terminals/v1/listAPI
Update terminal operating mode	PATCH /point/integration-api/devices/{device_id}API	PATCH /terminals/v1/setupAPI
Create payment intent vs. Create order	POST /point/integration-api/devices/{deviceid}/payment-intentsAPI	POST /v1/ordersAPI
Get payment intent vs. Get order	GET /point/integration-api/payment-intents/{paymentintentid}API	GET /v1/orders/{orderid}API
Cancel payment intent vs. Cancel order	DELETE /point/integration-api/devices/{deviceid}/payment-intents/{paymentintentid}API	POST /v1/orders/{orderid}/cancelAPI
Refund order	No dedicated endpoint existed	POST /v1/orders/{orderid}/refundAPI

Adapt the headers

The Orders API introduces two mandatory header changes that affect all endpoints: the sandbox mechanism was removed and a new idempotency control was introduced. Apply the following changes before testing any other resource.

Remove the x-test-scope header

Add the X-Idempotency-Key header

The X-Idempotency-Key header is required for order creation, cancellation, and refund operations. It ensures that a repeated request with the same key returns the original result without processing the operation again. Send a unique UUID v4 or random string per request. GET operations do not require this header.

If the same X-Idempotency-Key is reused with a different body, the API will return the idempotency_key_already_used error. Generate a new key for each distinct operation.

Update terminal listing and configuration

The terminal endpoints changed URL: listing moves from GET /point/integration-api/devices to GET /terminals/v1/list and mode update moves from PATCH /point/integration-api/devices/{device_id} to PATCH /terminals/v1/setup. In the mode update, the terminal identifier also moves from the path to the body, allowing multiple terminals to be updated in a single call.

Migrate the terminal listing

In the Payment Intent API, devices were returned in the devices array. In the Orders API, they move to data.terminals. The query params store_id, pos_id, limit, and offset remain the same. The table below describes the response changes.

Payment Intent API	Orders API	Description	Change
`devices[]`	`data.terminals[]`	List of terminals associated with the account. In the Payment Intent API, it was returned as a direct array in `devices`. In the Orders API, it is moved inside the `data` object and renamed to `terminals`.	Renamed and moved inside the `data` object.
`devices[].id`	`data.terminals[].id`	Unique terminal identifier. The last characters match the serial number on the back label of the terminal.	Same concept. The ID format may vary depending on the terminal model.
`devices[].pos_id`	`data.terminals[].pos_id`	Identifier of the point of sale associated with the terminal.	No changes.
`devices[].store_id` (integer)	`data.terminals[].store_id` (string)	Identifier of the store associated with the terminal. In the Payment Intent API, it was returned as integer. In the Orders API, it is returned as string.	Changes from integer to string.
`devices[].external_pos_id`	`data.terminals[].external_pos_id`	External point of sale identifier, defined by the integrator.	No changes.
`devices[].operating_mode`	`data.terminals[].operating_mode`	Terminal operating mode. In the Payment Intent API, the possible values are `PDV` and `STANDALONE`. In the Orders API, the `UNDEFINED` value is added for unrecognized configurations.	Adds the `UNDEFINED` value for unrecognized configurations.
`paging.total` / `paging.offset` / `paging.limit`	`paging.total` / `paging.offset` / `paging.limit`	Listing pagination data: total records, start point, and limit.	No changes.

In the terminal listing, errors are grouped by type of change. See the tables below for more details.

Errors not documented in the Orders API

The following errors exist in the Payment Intent API but are not documented in the Orders API.

HTTP	Payment Intent API	Note
`400`	`bad_request`	Required parameter missing or with incorrect format.
`400`	`bad_request`	Invalid request format.
`403`	`forbidden`	Present in the Payment Intent API.

Errors that remain unchanged

The following errors have the same behavior in both APIs.

HTTP	Error	Note
`401`	`unauthorized`	Invalid or expired token.
`500`	`internal_error`	Internal error. Check the response and retry.

Migrate the operating mode update

In the Payment Intent API, only one terminal could be updated per call and its identifier was sent in the path. In the Orders API, the identifier moves to the body inside the terminals[] array, allowing multiple terminals to be updated in a single call.

Below is a comparative example of an operating mode update.

Operating mode update via the Payment Intent API. The terminal identifier is sent as a path param.

curl
curl -X PATCH \
  'https://api.mercadopago.com/point/integration-api/devices/{{DEVICE_ID}}' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}' \
  -d '{
    "operating_mode": "PDV"
  }'

In the Payment Intent API, the response returns only the operating_mode field. In the Orders API, the response returns the terminals[] array with id and operating_mode, identifying each updated terminal. See the table below for the complete mapping.

Payment Intent API	Orders API	Description	Change
`operating_mode`	`terminals[].operating_mode`	Operating mode defined for the terminal. In the Payment Intent API, it was returned as a single field. In the Orders API, it is returned inside the `terminals[]` array. The possible values are `PDV` and `STANDALONE`.	Moves inside the `terminals[]` array.

The Orders API also introduces the following field with no equivalent in the Payment Intent API.

Field	Description
`terminals[].id`	Unique identifier of the updated terminal. It is returned only in the Orders API.

In the operating mode update, errors are grouped by type of change. See the tables below for more details.

Errors that disappear

The following error exists in the Payment Intent API but was removed in the Orders API.

HTTP	Payment Intent API	Note
`424`	`failed_dependency`	Code removed in the Orders API.

Renamed errors

The following error was renamed in the Orders API.

`403`	`forbidden`	`store_pos_not_found`	Terminal has no associated store or point of sale.

Errors that change behavior

The following error exists in both APIs but with a different meaning in the Orders API.

HTTP	Payment Intent API	Orders API	Note
`400`	`bad_request`	`property_value`	Invalid `device_id` or `operating_mode` value.

Errors that remain unchanged

The following errors have the same behavior in both APIs.

HTTP	Error	Note
`401`	`unauthorized`	Invalid or expired token.
`500`	`internal_error`	Internal error. Retry the request.

Errors introduced by the Orders API

The following errors have no equivalent in the Payment Intent API.

HTTP	Orders API error	Note
`400`	`unsupported_site`	Invalid site.
`400`	`required_properties`	Required property missing.
`400`	`unsupported_properties`	Unsupported field sent.
`400`	`invalid_payload`	Invalid payload. Check the submitted fields.
`403`	`terminal_not_allowed_action`	Action not allowed for this terminal model.
`404`	`not_found`	Resource not found or invalid ID.
`412`	(no string code)	Operation not allowed: a terminal is already associated with the point of sale in PDV mode. Only one terminal per point of sale is allowed in PDV mode.

Migrate payment intent creation to order creation

The creation endpoint changes from POST /point/integration-api/devices/{deviceid}/payment-intents to POST /v1/orders. Beyond the URL change, the request structure was significantly reorganized: the terminal identifier moves from the path to the body, new required fields were introduced, and the Orders API has a distinct structure. Follow the steps below to adapt the request, response, and error handling.

curl
curl -X POST \
  'https://api.mercadopago.com/v1/orders' \
  -H 'Content-Type: application/json' \
  -H 'X-Idempotency-Key: {{IDEMPOTENCY_KEY}}' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}' \
  -d '{
    "type": "point",
    "external_reference": "ext_ref_1234",
    "transactions": {
      "payments": [
        {
          "amount": "24.00"
        }
      ]
    },
    "config": {
      "point": {
        "terminal_id": "{{TERMINAL_ID}}",
        "print_on_terminal": "no_ticket"
      }
    },
    "description": "Point Smart 2"
  }'

Map the request body fields

The Orders API has a different structure from the Payment Intent API: the terminal identifier must be sent in the body, payment and printing configuration fields are placed in new nodes, and identification headers become part of the body. The new required fields are type (with value "point") and external_reference. See the table below for the complete field mapping.

Below is a comparative example between creating a payment intent and creating an order, followed by the complete field mapping table.

Request to create a payment intent. The terminal identifier is sent as a path param and amount is an integer value.

curl
curl -X POST \
  'https://api.mercadopago.com/point/integration-api/devices/{{DEVICE_ID}}/payment-intents' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}' \
  -H 'x-test-scope: sandbox' \
  -d '{
    "amount": 1500,
    "additional_info": {
      "external_reference": "order-ref-001",
      "print_on_terminal": true
    },
    "description": "Test product"
  }'

Payment Intent API	Orders API	Description	Change
`{deviceid}` (path param)	`config.point.terminal_id`	Identifies the terminal that will receive the order. In the Payment Intent API, it is sent as a path parameter. In the Orders API, it is sent in the body in the format `{terminal_type}__{terminal_serial}`.	Moves from path param to body field.
`amount` (integer)	`transactions.payments[].amount` (string)	Amount to charge. In the Payment Intent API, it is represented as an integer with implicit two decimals (e.g.: `1500` for $15.00). In the Orders API, it is represented as a string inside the `transactions.payments` array. Accepts two decimal places (e.g.: `"15.00"`) or none. Only 1 transaction per order is allowed when `type` is `point`.	Changes from integer to string and enters the `transactions.payments` array.
`additional_info.external_reference`	`external_reference`	Alphanumeric identifier for the transaction in the integrator's system, returned in webhook notifications. In the Orders API, it is required, with a maximum of 64 characters, only letters, numbers, `-` and `_`. Must be unique per order and cannot contain PII data.	Moves to root level and becomes required.
`additional_info.print_on_terminal` (boolean)	`config.point.print_on_terminal` (string)	Controls ticket printing on the terminal. In the Payment Intent API, it accepts the boolean values `true` and `false`. In the Orders API, it accepts the values `seller_ticket` (prints) and `no_ticket` (does not print). Default value: `seller_ticket`.	Changes from boolean to enum string.
`payment.type`	`config.payment_method.default_type`	Defines the payment method accepted by the terminal. In the Payment Intent API, the possible values are `credit_card`, `debit_card`. In the Orders API, the possible values are `credit_card`, `debit_card`, and `qr`. If not sent, the terminal accepts all payment methods.	Changes node and now also accepts `qr`.
`description`	`description`	Describes the product, service, or payment reason. In the Orders API, it accepts up to 150 characters.	No changes.
`X-platform-id` (header)	`integration_data.platform_id`	Identifies the integration platform, assigned by Mercado Pago. In the Payment Intent API, it was sent as a header. In the Orders API, it is sent in the body inside `integration_data`.	Moves from header to body.
`X-integrator-id` (header)	`integration_data.integrator_id`	Identifies the integrator, assigned by Mercado Pago. In the Payment Intent API, it was sent as a header. In the Orders API, it is sent in the body inside `integration_data`.	Moves from header to body.
`additional_info.ticket_number`	`config.point.ticket_number`	Alphanumeric value to identify the invoice or ticket number, printed on the terminal when printing is enabled.	Moves to `config.point`.

The Orders API also introduces the following fields with no equivalent in the Payment Intent API.

Field	Description
`integration_data.sponsor.id`	USER_ID of the Mercado Pago account of the integrating system.
`type`	Order type. For Point, the only accepted value is `"point"`. Required.
`expiration_time`	Defines the order validity period from creation, in ISO 8601 format. The minimum value is `PT30S` (30 seconds), the maximum value is `PT3H` (3 hours) and the default value is `PT15M` (15 minutes). Examples: `PT30S` for 30 seconds, `PT10M` for 10 minutes, `PT1H15M` for 1 hour and 15 minutes. If the order expires without being processed, it is automatically canceled. Optional.

The order ID format changes from UUID (e.g.: 7f25f9aa-eea6-...) to alphanumeric (e.g.: ORD00001111222233334444555566). Update any storage or query logic that depends on the ID format before proceeding.

Check all available parameters in the API ReferenceAPI.

Adapt the creation response fields

The table below shows the creation response fields that existed in both APIs and were updated during the migration.

Payment Intent API	Orders API	Description	Change
`id` (UUID)	`id` (alphanumeric)	Order identifier, generated by Mercado Pago. In the Payment Intent API, it is returned in UUID format. In the Orders API, it is returned in alphanumeric format with `ORD` prefix.	ID format changes to `ORD...`.

Update error handling in creation

In creation, errors are grouped by type of change. See the tables below for more details.

Errors that change behavior

In the Payment Intent API, the following errors returned the generic bad_request code. In the Orders API, they are replaced by specific codes.

HTTP	Payment Intent API	Orders API	Note
`400`	`bad_request`	`required_properties`	Required property missing.

The order identifier in the path also changes from UUID to alphanumeric format. The response includes new fields with information about the payment result, refunds, and card data.

curl
curl -X GET \
  'https://api.mercadopago.com/v1/orders/{{ORDER_ID}}' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}'

Adapt the query response fields

In addition to the fields documented in the creation response, the GET response includes additional fields relevant to the migration. See the table below for details.

Payment Intent API	Orders API	Description	Change
`state`	`status`	Order status. In the Payment Intent API, `state` field with uppercase values. In the Orders API, `status` field with lowercase values and an expanded set of statuses.	Renamed. See the complete mapping in Update status handling.
`payment.id` (integer)	`transactions.payments[].reference_id` (string)	Identifier of the processed payment, available when the flow completes successfully. In the Payment Intent API, it was returned as an integer in `payment.id`. In the Orders API, it is returned as a string in `transactions.payments[].reference_id`.	Processed payment identifier. Changes from integer to string.

The Orders API also introduces the following fields with no equivalent in the Payment Intent API.

Field	Description
`status_detail`	Order status detail. Possible values: `accredited`, `canceled_by_api`, `bad_filled_card_data`, `insufficient_amount`, among others. See the API Reference for the complete list.
`transactions.payments[].paid_amount`	Amount effectively paid in the transaction.
`transactions.payments[].refunded_amount`	Amount refunded in the transaction.

`transactions.refunds[]`	Array with the refund data for the order (`id`, `transaction_id`, `reference_id`, `amount`, `status`).

Update error handling in query

In the query, errors are grouped by type of change. See the tables below for more details.

Errors that disappear

The following errors exist in the Payment Intent API but have no equivalent in the Orders API.

HTTP	Payment Intent API	Note
`401`	`unauthorized` (Unauthorized use of live credentials)	The `x-test-scope` header was removed in the Orders API.
`403`	`forbidden`	Terminal ownership validation occurs only during creation.
`429`	`too_many_requests`	Present in the Payment Intent API. Not documented in the Orders API.

Renamed errors

The following error was renamed in the Orders API.

HTTP	Payment Intent API	Orders API	Note
`404`	`not_found`	`order_not_found`	Order not found. Verify that the submitted ID is correct.

Errors that change behavior

The following error exists in both APIs but with a different meaning in the Orders API.

HTTP	Payment Intent API	Orders API	Note
`400`	`bad_request`	`bad_request`	Invalid `order_id` format. The ID changes from UUID to alphanumeric.

Errors that remain unchanged

The following errors have the same behavior in both APIs.

HTTP	Error	Note
`401`	`unauthorized`	Invalid or expired token.
`500`	`internal_error`	Internal error. Retry the request.

Update status handling

One of the most significant changes between the Payment Intent API and the Orders API is the state field, which is renamed to status in the new API and receives new values. In the Payment Intent API, the FINISHED status required additional calls to determine the actual payment result. In the Orders API, the processed and failed statuses are self-contained and eliminate that need. Update all status checks in your integration according to the table below.

Map status values

Payment Intent API (`state`)	Orders API (`status`)	Note
`OPEN`	`created`	Renamed
`ON_TERMINAL`	`at_terminal`	Renamed
`PROCESSING`	Absorbed	No intermediate status in the Orders API
`PROCESSED`	Absorbed	No intermediate status in the Orders API
`FINISHED` (approved payment)	`processed`	The approved payment result is contained in the order itself, without requiring additional queries.
`FINISHED` (rejected payment)	`failed`	The rejected payment result is contained in the order itself, without requiring additional queries.
`CONFIRMATION_REQUIRED`	`action_required`	Renamed
`ERROR`	`failed`	Renamed
`ABANDONED`	`expired`	Renamed (timeout-based)
`CANCELED`	`canceled`	Same meaning. Now lowercase
Does not exist	`refunded`	New status. Must be handled explicitly in all flows

In the Payment Intent API, confirming the result of a payment with state: FINISHED required inspecting payment.state in the webhook, calling GET /v1/payments/{id}, or searching by external_reference. In the Orders API, the processed and failed statuses are self-contained: the payment result is available directly in the order, without additional queries.

Update order cancellation

The new endpoint to cancel an order is POST /v1/orders/{orderid}/cancel, replacing the DELETE from the Payment Intent API. The {deviceid} is removed from the path and the cancellation is now identified solely by the {orderid}.

In the Payment Intent API, it was only possible to cancel payment intents that had not yet reached the terminal. In the Orders API, it is possible to cancel an order even after it has reached the terminal, using a new specific header.

curl
curl -X POST \
  'https://api.mercadopago.com/v1/orders/{{ORDER_ID}}/cancel' \
  -H 'Content-Type: application/json' \
  -H 'X-Idempotency-Key: {{IDEMPOTENCY_KEY}}' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}'

Adapt cancellation headers

The response now returns the complete order object with status: "canceled", instead of just the id. The headers required for this operation are:

Header	Required	Description
`X-Idempotency-Key`	Required	Unique key per request
`x-allow-cancelable-status`	Conditional	Required to cancel orders in `at_terminal`. Value: `"at_terminal"`

To cancel orders with at_terminal status, send the x-allow-cancelable-status: at_terminal header. Without this header, only orders with status: created will be canceled.

Update error handling in cancellation

In cancellation, errors are grouped by type of change. See the tables below for more details.

Errors that disappear

The following errors exist in the Payment Intent API but have no equivalent in the Orders API.

HTTP	Payment Intent API	Note
`400`	`bad_request` (deviceID format)	`deviceid` was removed from the path in the Orders API.
`429`	`too_many_requests`	Present in the Payment Intent API. Not documented in the Orders API.

Renamed errors

The following error was renamed in the Orders API.

HTTP	Payment Intent API	Orders API	Note
`409`	`conflict_error`	`cannot_cancel_order`	Order status does not allow cancellation. For `at_terminal`, send `x-allow-cancelable-status: at_terminal`.

Errors that change behavior

The following errors exist in both APIs but with different behavior in the Orders API.

HTTP	Payment Intent API	Orders API	Note
`400`	`bad_request`	`bad_request`	Invalid `order_id` format. The ID changes from UUID to alphanumeric.
`404`	`101`	`order_not_found`	Order not found. In the Payment Intent API, the `error` field uses the numeric code `"101"`.
`409`	`101`	`order_already_canceled`	In the Payment Intent API, non-existent orders and already-canceled orders returned the same `"101"` error. In the Orders API, they are differentiated into two distinct errors: `404` for order not found and `409` for order already canceled.
`500`	`internal_error`	`idempotency_validation_failed`	Idempotency validation failure. Retry the request.

Errors that remain unchanged

The following error has the same behavior in both APIs.

HTTP	Error	Note
`401`	`unauthorized`	Invalid or expired token.

Errors introduced by the Orders API

The following errors have no equivalent in the Payment Intent API.

HTTP	Orders API error	Note
`400`	`empty_required_header`	`X-Idempotency-Key` missing.
`409`	`idempotency_key_already_used`	Idempotency key reused.

Implement refunds with the dedicated endpoint

The Orders API introduces the dedicated endpoint POST /v1/orders/{orderid}/refund for refunds, which did not exist in the Payment Intent API. Previously, it was necessary to receive the payment webhook, obtain the payment_id, and execute the refund through the Payments API separately. Now, the refund is performed directly on the order.

Replace the Payment Intent API refund flow

Choose between a full or partial refund based on the amount to return.

To refund the full order amount, send the request to the POST /v1/orders/{orderid}/refundAPI endpoint without a body.

curl
curl -X POST \
  'https://api.mercadopago.com/v1/orders/{{ORDER_ID}}/refund' \
  -H 'Authorization: Bearer {{ACCESS_TOKEN}}' \
  -H 'X-Idempotency-Key: {{IDEMPOTENCY_KEY}}'

Refunds are accepted up to 90 days from the payment date.

See all possible error codes for this operation in Refund errors.

Adapt the refund response fields

The refund response varies depending on the type of operation performed.

Field	Type	Description
`id`	string	Identifier of the refunded order
`status`	string	`refunded` for full refund. `processed` for partial refund (balance still available)
`status_detail`	string	`refunded` for full refund. `partially_refunded` for partial refund
`transactions.refunds[].id`	string	Refund identifier, generated by Mercado Pago
`transactions.refunds[].transaction_id`	string	Identifier of the payment transaction being refunded
`transactions.refunds[].reference_id`	string	Identifier linking the payment and its refund
`transactions.refunds[].amount`	string	Refund amount
`transactions.refunds[].status`	string	`processing` when a full refund was requested and is being processed. `processed` when a partial refund was successfully completed

Validate the migration

After applying the changes, verify that the integration works correctly across all flows before going to production.
