We take the utmost care in ensuring that changes to our APIs do not break your integrations. We consider the following changes to be backward-compatible:

• Adding new API resources/endpoints.
• 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).

Note that the above also applies to changes in our webhook event schemas.

In the event that a breaking change is completely unavoidable (e.g., for compliance reasons), we will contact you in advance to ensure that you have sufficient time to update your integration.
