The API guides provide detailed technical information to help you seamlessly integrate with the API. APIs are organized alphabetically for easy navigation. You'll learn about the authorisation grant types used, the necessary entitlements, supported certificate types, and other critical technical aspects. Additionally, the guides reference other important documents, such as business rule books, that are essential during development. Whether you're testing the APIs in the sandbox or integrating them into Pilot or Live environments, these resources will help you integrate the APIs in your applications with ease and confidence.
