PSE via direct API

This page includes the steps necessary to integrate PSE using the DEUNA API.

Use the V2 endpoint for direct API integrations.

📘
For more information, refer to the Payments API.

V2 purchase

V2 purchases perform the two steps in a single endpoint by adding the order information in the request.

The V2 purchase process goes as follows:

User calls POST v2/merchants/order/purchase with the order information in the CURL request.
The internal service creates the order and performs the purchase operation.

Integrate PSE by API

Direct API integrations follow the V2 process.
