Create a credential
Credentials module
POST/credentialscredentials.create
An issued credential. Credentials cannot be self-issued. Creates a credential. Requires `Idempotency-Key`; a replay returns the original response. The organization is derived from the credential or the parent row, never from the body.
- Requires the capability credentials.credential.issue.
- OAuth scopes: credentials.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 409, 422, 429. Errors are RFC 9457 problem details.
