Payment processing

To start processing your payments with Point of Sale (POS), follow the steps below.

Get the list of your available devices

Before creating a payment intent, you must obtain the list of Point devices associated with your account. You can do it through the following call:

curl

curl --location --request GET 'https://api.mercadopago.com/point/integration-api/devices?offset=0&limit=50' \ 
--h 'Authorization: Bearer YOUR_ACCESS_TOKEN' 

You will receive a response like this:

json

{
    "devices": [
        {
            "id": "PAX_A910__SMARTPOS1234345545",
            "pos_id": 47792476,
            "store_id": "47792479",
            "external_pos_id": "SUC0101POS",
            "operating_mode": "PDV"
        },
        {
            "id": "INGENICO_MOVE2500__ING-ARG-12348394345",
            "pos_id": 47792476,
            "store_id": "47792476",
            "external_pos_id": "SUC0102POS",
            "operating_mode": "STANDALONE"
        },
        {
            "id": "INGENICO_MOVE2500__ING-ARG-4782743403",
            "operating_mode": "PDV",
            "pos_id": 47792476,
            "store_id": "47792478",
            "external_pos_id": "SUC0103POS",
        },
        {
            "id": "PAX_A910__SMARTPOS849233453",
            "pos_id": 47792476,
            "store_id": "47792472",
            "external_pos_id": "SUC0104POS",
            "operating_mode": "STANDALONE"
        }
    ],
    "paging": {
        "total": 4,
        "limit": 50,
        "offset": 0
    }
}

Create the payment intent

A payment intent is a call that contains all the details of the transaction to be made, and it must be created in order to start a payment. It is an attempt that, if successful, will return a payment id and its status.

You can create a payment intent and assign it to your Point device in the following way:

curl

curl --location --request POST 'https://api.mercadopago.com/point/integration-api/devices/{deviceid}/payment-intents' \
--h 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
--data-raw '{
   "amount": 1500,
   "additional_info": {
       "external_reference": "4561ads-das4das4-das4754-das456",
       "print_on_terminal": true,
       "ticket_number": "S0392JED"
   }
}'
FieldDescription
amountTotal amount of the payment intent.
Important: this field does not allow decimal points. Therefore, if you want to generate a payment intent, you must consider the two decimals of the value in its total. For example: to generate payment order value "15.00" you must enter "1500".
external_referenceField exclusively used by the integrator to include references to their system.
print_on_terminalField that determines if the device prints the payment receipt.
ticket_numberTicket number of the payment intent.

In response, you will receive something similar to this:

json

{
 "id": "7d8c70b6-2ac8-4c57-a441-c319088ca3ca",
 "device_id": "INGENICO_MOVE2500__ING-ARG-14886780",
 "amount": 1500,
 "additional_info": {
     "external_reference": "4561ads-das4das4-das4754-das456",
     "print_on_terminal": true,
     "ticket_number": "S0392JED"
 }
}

Please note that payment intents are the foundation for processing payments with Point devices. For this reason, it is important that you register and save the data obtained during their creation, especially their id.

Process your payment intent

Once the payment intent has been created, you can obtain it from your Point device by pressing on the key to pay (in the case of Point Plus and Point Pro 2 the green button and, in the case of the Point Smart, the digital button “Cobrar”).

Then, follow the steps shown on the screen afterwards to complete the payment.

Important
We recommend assessing your integration’s quality to check if you are meeting the Mercado Pago quality and security standards that would help you obtain a good payment approval rate.

Check the status of your payment intent

If you want to know the status of a particular payment intent, you can check the current status of your payment intent using the id that you received in the response when creating it.

Attention
Keep in mind that it's only possible to check the status of a payment intent that was created up to, at most, 3 months ago. Make sure to use the identifier (id) corresponding to the payment attempt that falls within this period. If you need information about older payment intents, we recommend contacting our customer service for additional assistance.

Remember that idand statusof the payment intent (for example, 7f25f9aa-eea6-4f9c-bf16-a341f71ba2f1) are not the same as idand statusof the payment (for example, 65412345). In this case, you will be trying to obtain the details of an attempt. If you want to check out all the information corresponding to the payment, access the Payment API section in our API Reference.

Important
The main recommended mechanism to know the result of a payment intent is the subscription to integration notifications . The endpoint presented here is recommended only as an alternative mechanism.

curl

curl --location --request GET 'https://api.mercadopago.com/point/integration-api/payment-intents/
{paymentintentid}' \
--h 'Authorization: Bearer YOUR_ACCESS_TOKEN'

You will receive a response similar to this one below:

json

{
    "state": "FINISHED",
    "id": "0aa0519d-d985-4e83-b62d-dda123456789",
    "device_id": "INGENICO_MOVE2500_ING-ARG-14123456",
    "amount": 600,
    "payment": {
        "id": "11123456789"
    },
    "additional_info": {
        "ticket_number": "123456789123456789"
    }
}
Important
Confirmation_required is a final status and will not change. If you receive it as a response to the payment intent, you must check on your device the status of the payment, using the payment_id given in said response. Do not deliver your service or product until you verify it.

You can check all the possible status of a payment intent by accessing our Glossary.

Cancel a payment intent

If you want to, you can cancel a payment intent assigned to a Point device. To do so, you have two posibilities:

  • If the status of the intent is open and it has not yet been sent to the terminal, you can cancel it via API by making the following call:

curl

curl --location --request DELETE 'https://api.mercadopago.com/point/integration-api/devices/{deviceid}/payment-intents/{paymentintentid}' \
--h 'Authorization: Bearer YOUR_ACCESS_TOKEN' \

You will receive this response:

json

{
 "id": "7d8c70b6-2ac8-4c57-a441-c319088ca3ca"
}
  • If the status of the payment intent is on_terminal, you will need to cancel it directly from the Point device.
Recommendation
You can use the Point Simulator to safely test your integration and the creation of payment intents by using your test account and credentials.
