The Paybis Send API is structured around REST, HTTP, and JSON. It uses HTTP methods for indicating the action to take on a resource and HTTP status codes for expressing error states.

Base URL

The API is accessed using a base URL:

Sandbox: cs-api.sandbox.paybis.com
Prod: cs-api.paybis.com

All API calls should be made over HTTPS.
Generally, the URL will be in the form https://<base-url>/v1/<resource>, for example, https://cs-api.paybis.com/v1/quote

Authentication

All requests to the API are authenticated by providing your API key. The API key should be provided in a form of Bearer authentication:
Authorization: Bearer <token>

Also, the request should be signed with the private RSA key.
