get_sign_status
Checks whether the current consented user has completed passwordless payment signing with the provider. Before placing an order (create_order), confirm that signed is true; if not signed, follow the returned next_action to guide the user through signing. Signing status is queried live from upstream using the consent context (user, device); the caller does not pass a mobile number or device ID.
Signing flow: call
get_sign_status to check signed → if false, call get_sign_action to get an H5 signing URL and guide the user to complete signing in a browser → call get_sign_status again to confirm signed becomes true → proceed to the order flow.Parameters
The mobile number, device ID, and signing channel needed for the lookup are all derived by the gateway from the consent context; the caller neither needs nor can pass them.
