#Changelog

#Compatibility promise

Zaps, scenarios and custom integrations built on this API are expected to run for years, so we only make additive changes to what's documented here:

• We may add new endpoints, new optional parameters, new response fields, new event types, and new values for fields documented as open-ended (such as stamp source).
• We won't remove or rename a documented field, endpoint, parameter or event, or change what it means.

Build your client to ignore fields it doesn't recognize. Any breaking change would go to a new versioned path, announced here well in advance.
