Conventions

  • Identifiers. Customer ids are UUIDs. Wherever a {id} path parameter appears, you can also pass your own external_id — we detect the format and resolve accordingly.
  • Timestamps. ISO-8601 with offset (2026-06-23T01:12:00Z).
  • Pagination. Cursor-based. See Pagination.
  • Idempotency. Pass Idempotency-Key on writes. See Idempotency.
  • Errors. Standard envelope. See Errors.
