These two resources describe the same contract as the API reference in a structured form, so you can use them as tooling for your integration rather than reading them. Parameters, responses, statuses and errors are still defined and explained in the reference pages: Transactions, Payment by link and Errors.

​
OpenAPI contract

Download the OpenAPI specification OpenAPI 3.1 file covering the 5 merchant operations (payments and payment links), their headers, parameters, responses and errors. Use it to:
  • import the contract into an HTTP client (Insomnia, Bruno, an editor plugin);
  • generate a client or types in your language from the schema;
  • automatically validate your requests/responses in your integration tests.

​
Postman collection

Download the Postman collection A collection ready to import into Postman, with one example request per operation. Use it to explore the API and make your first calls without writing code, before moving on to a server-side integration. The descriptions in this collection are currently in French. The values to substitute for a first call in Sandbox (test numbers, minimum amount) are in the Sandbox and testing guide.
