Flowchart
Key Steps
Mark transaction with "funds-distribution"
See【funds-distribution Mark API】for details: Before a merchant transaction, call the API to mark it with "funds-distribution", indicating that the transaction will subsequently be subject to the funds-distribution function. After the payment is completed, the transaction funds will be frozen in the merchant's account, waiting for the funds-distribution command or unfreeze remaining funds command from the merchant to distribute the funds.
Note: The mark API must be called before the merchant calls the transaction API, and its parameters must be consistent with those of the transaction API (sub-merchant, transaction ID and price currency). Otherwise, the funds-distribution mark will be invalid.
Merchants adding receivers
Before calling【funds-distribution Request API】, the merchant needs to add a receiver and submit relevant documents to prove the relationship of the funds receiver for compliance verification. The merchant can call【Adding Receiver Result Query API】to query the result of adding a receiver. After successful addition (after the submitted documents are approved), the funds can be distributed to the receiver.
