Backend API Changes - v1.67.0

Release: v1.67.0 Date: 2026-06-10

Breaking Changes: NO Action Required: NO

Summary

This release makes no changes to endpoint paths, request shapes, or authentication. Two changes affect response data and persistence, both backwards compatible.

Modified Behaviour

GA shape metadata now carries `fontScale`

The renderer metadata for general-admission sections now includes an additive fontScale field per GA shape, so the booking renderer can size GA labels exactly as the editor does (SEAT-1002).

Field: fontScale (integer, optional) on GA shape metadata.
Compatibility: additive. Consumers that ignore unknown fields are unaffected; clients on this release use it to render GA labels at the authored size instead of a default scale.

Price `externalId` is now persisted

Previously the API echoed a price externalId on the way in but did not store it, so it was lost on reload. It is now persisted and round-trips correctly (SEAT-1001).

Endpoint surface: unchanged - the field was already present in the price payload.
Behaviour: a saved externalId is now returned on subsequent reads.
Action: none. Integrations that set externalId will simply see it survive a save/reload.

Unchanged

No new, removed, or renamed endpoints.
No authentication or authorization changes to public endpoints.
No request/response format changes beyond the additive fontScale field above.
No rate-limit or webhook changes.

Note: new admin-only plan and tenant management endpoints ship with this release (SEAT-1027). They are part of the internal admin surface and are covered in the Deployment Guide, not the integrator-facing API.
