API versioning - Flatpeak

A version is a named release, such as 2027-01-01.busbar, and one version covers the Energy API and the Fleet API. Moving to another version can require code changes; compatible changes do not change the version.

Set the version

Requests use your account’s default version. To override it for one request, send the Flatpeak-Version header:

curl -I --request GET \
  --url "https://fleet-api.flatpeak.com/devices/dev_63a6087272941ef077a8fd3e" \
  --header 'Authorization: Bearer <bearer_token>' \
  --header 'Flatpeak-Version: 2027-01-01.busbar'

The response returns the version in its flatpeak-version header. A version older than your account default returns 422 api_version_not_supported. To change the default, go to Console > Settings > Versions > API Versions. Test the version with the header first, because you cannot downgrade.

Webhooks

A webhook event uses the version its object was created with, unless you have changed the account default.

Support

A supported version keeps its endpoints, gets security and bug fixes, and is covered by the service level agreement. Capabilities are added to the newest version only.
