\# Integrate payment processing Payment processing with Mercado Pago Point integrated into your point of sale is based on creating orders that have an associated payment transaction. When an order is created, it will be automatically loaded to the specified terminal, and the buyer will be able to make the payment in person. Integrated payment processing with Mercado Pago Point will allow you to create orders, process them, cancel them, or make refunds and query their information or status updates. > NOTE > > If you want the installments set to be \[with\](https://www.mercadopago.com.ar/ayuda/24694) or \[without\](https://www.mercadopago.com.ar/developers/es/support/cuotas-sin-interes\_3299) interests, before creating an order, you must \*\*set them up in your Mercado Pago account\*\*. :::AccordionComponent{title="Create an order"} To start processing payments with Point from points of sale, you first need to identify which terminal you want to assign the order to. Remember that this terminal must be \[set to PDV mode\](https://www.mercadopago.com.ar/developers/en/reference/in-person-payments/point/terminals/update-operation-mode/patch). For this, send a \*\*GET\*\* to the endpoint :TagComponent{tag="API" text="Get list of terminals" href="/developers/en/reference/in-person-payments/point/terminals/get-terminals/get"}. Use your :toolTipComponent\[test Access Token\]{link="/developers/en/docs/mp-point/create-application#bookmark\_access\_test\_credentials" linkText="Access test credentials" content="Private key of the application created in Mercado Pago, used in the \_backend\_ during integration development. You can access it in \*Your integrations > Integration data > Tests > Test credentials\*. When going to production, replace it with the production Access Token if it is your own integration, or with the Access Token obtained via OAuth in the case of third-party integrations."}. We recommend filtering the search by using the optional query params \`store\_id\` and \`pos\_id\`, store and box identifiers returned in the response to the creation of each one. \`\`\`curl curl -X GET \\ 'https://api.mercadopago.com/terminals/v1/list?limit=50&offset=0&store\_id=12354567&pos\_id=23545678' \\ -H 'Content-Type: application/json' \\ -H 'Authorization: Bearer TEST-232\*\*\*\*\*\*\*\*97488-12\*\*\*\*\*\*\*\*26f67454\*\*\*\*\*\*\*\*f4c8b49c\*\*\*\*\*\*\*\*9526408' \`\`\` The response to this request will allow you to see the terminals associated with your account and select the one you want to use to create your order.

This created order will be automatically received by the terminal to which it was assigned. If the order is not automatically loaded on the terminal, you must press the \*\*Update\*\* button or, if the terminal has one, the \*\*green button\*\* to receive the order.
