Common Patterns

Authentication

All endpoints except /helo require a session token (xa-token) as a Bearer token. See the Authentication guide.

Nonce

All POST and PUT endpoints require a nonce query parameter. See Session Management.

Pagination

List endpoints support skip and limit parameters. See Pagination & Filtering.

Errors

All error responses follow the apiError schema. See Error Handling.
