API Version
The current SSN API payload version is:
2026-03-24
Webhook payloads include this value in the payloadVersion field. Clients should store and log the version when processing webhook events.
Compatibility
The API is intended to remain backward-compatible for existing client integrations.
Backward-compatible changes may include:
- adding optional request fields
- adding response fields
- adding webhook event fields
- adding new endpoints
- adding new enum values where clients are expected to tolerate unknown values
Breaking changes require explicit client coordination before rollout.
