The Automation API uses semantic versioning.

About entire API versioning

Breaking changes are only released in new major versions of the API with the following exceptions:

  • Endpoints that are not yet in use may contain breaking changes in a minor version (1.x).
  • Important security bugs that break backward compatibility fixes may be released in a minor version. All API changes are available in the API changelog

Breaking changes include the following types of changes:

  • Removing an entire operation.
  • Removing or renaming a parameter.
  • Removing or renaming a response field.
  • Adding a new required parameter.
  • Making a previously optional parameter required.
  • Changing the type of a parameter or response field.
  • Removing enum values.
  • Adding a new validation rule to an existing parameter.
  • Changing authentication or authorization requirements.

Any additive (non-breaking) changes will be available in all supported API versions. Additive changes are changes that should not break an integration. Additive changes include:

  • Adding an operation.
  • Adding an optional parameter.
  • Adding an optional request header.
  • Adding a response field.
  • Adding a response header.

About API per-endpoint versioning

Some endpoints allow you to specify a specific version of that endpoint to use. For example, you might want to use a newer version of one specific endpoint than the rest of your API calls. Where available, use the version parameter to specify your desired endpoint version.

However, when a new major version is released, all previous versions are removed. For example, if an endpoint has version 1 and version 2 in the 1.0.0 API version, the 2.0.0 API version will only contain the latest version of the endpoint.
