 Backward-compatible changes

We consider the following changes to be backward-compatible:

  • Adding new, optional request fields/parameters to existing APIs.
  • Adding new fields to existing API responses.
  • Adding new, optional HTTP request headers.
  • Adding new HTTP response headers.
  • Increasing the length of existing string field values.
  • Changing the format of identifiers including changing or removing prefixes.
  • Adding new webhook event types (you will need to explicitly opt into these).
  • Adding new fields to existing webhook event schemas.

We try to ensure that changes to our APIs do not break your integration, but if a breaking change is unavoidable (for compliance reasons, for instance), we’ll contact you in advance to ensure you have sufficient time to update your integration.
