API changes
Last updated: October 15, 2025
We take the utmost care to ensure that changes to our APIs do not break your integrations. 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 must explicitly subscribe to webhooks to receive them.
- Adding new fields to existing webhook event schemas
If a breaking change is unavoidable (for example, for compliance reasons), we contact you in advance to ensure you have sufficient time to update your integration.
