API Architecture

📘

REST

The Openpay API is organised around REST. The API attempts to use predictable, resource-oriented URLs and to use HTTP status codes to indicate errors.

🚧

HTTPS

The Openpay API requires all communications to be secured using TLS 1.2 or greater.

If you are connecting from Windows 7 or equivalent then you may need to upgrade to TLS 1.2.

📘

Request Headers

Clients must send appropriate headers with all requests.
