Key types

​
Top-level partner API key

  • Can access partner endpoints.
  • Can create child/sub-account API keys.
  • Can transfer balance to child accounts.

​
Child API key (sub-account)

  • Merchant-scoped key created under a top-level partner.
  • Cannot call top-level-only partner operations.
  • Can call regular trading, user, and wallet endpoints within its own account scope.

​
Access behavior

  • Endpoints marked top-level-only reject child keys.
  • Some partner market endpoints currently accept authenticated keys generally, but partner keys are the intended mode.
  • API key auth is the only supported integration auth mode.

Errors
