Record creation validation

​
Record creation now requires complete initial fields

Record creation now rejects empty field payloads and enforces fields configured as required for the target object.

​
Action required

  • REST POST /records requires a non-empty fields object.
  • Include every required field unless it has a configured default.
  • REST retries may use the optional Idempotency-Key header.
  • MCP records_create requires a stable idempotencyKey tool argument.

​
Migration

  1. List fields with GET /crm/objects/{objectTypeId}/fields.
  2. Include values for required fields without defaults.
  3. Reuse the same idempotency value when retrying the same logical request.
See Create a record and List CRM fields.
