API Protocol Specifications

The Application API is specified in the OpenAPI 3.0 format. Requests and responses can be crafted with auto-generated code using Swagger Codegen or OpenAPI Generator, are human-readable (easy to debug and understand), and can be used in servers and browsers.

The transactional API conforms to REST. It has predictable, resource-oriented URLs, and it uses HTTP response codes to indicate API errors. JSON is returned by all API responses, including errors

The query API conform to GraphQL, as such it offers significantly more flexibility for the application development. The ability to define precisely the data you want—and only the data you want—is a powerful advantage over the REST. GraphQL lets you replace multiple REST requests with a single call to fetch the data you specify.
