We periodically release new, dated versions of the API whenever we make breaking changes. Although we try to only make backward-compatible changes, sometimes we have to make a breaking change to iterate on the API. We consider the following changes backward compatible:
  • Adding new API endpoints
  • Adding new optional parameters to existing endpoints
  • Adding new data elements to existing responses
  • Adding new errors
Our current version is 2024-01-01 The Chart-API-Version header must be set for every single request to our API.
