Merchant Onboarding

This document describes how to integrate the merchant onboarding feature. Before you begin, please review the following:

• API Rules
• Signature Generation and Verification
• File Upload

• Merchant Onboarding Application: This API submits a merchant onboarding application
• The system returns a merchant ID merch_id and an account authorization link authorize_link
• The request_id in the request parameters is used for tracking the business process

The merchant must confirm the account opening on the authorization interface opened via the authorize_link

• Merchant Information Update: This API updates rejected onboarding applications
• The request_id in the request parameters must match the request_id from the onboarding application
• Only applications with status REJECTED can be updated
• After updating information, the merchant must re-confirm through the Account Confirmation step

• Query Merchant Onboarding Result: This API queries the review status of an onboarding application
• The request_id in the request parameters must match the request_id from the onboarding application
• Periodically call the query API to obtain the review status

• Merchant Onboarding Result (Notification): webhook for receiving asynchronous notifications
• Listen for callback notifications of type MERCH
• The request_id in the notification content is the request_id from the onboarding application

After the merchant is successfully onboarded (status is NORMAL), you can use the merchant ID (merch_id) to open a collection account. See Collection Account for details.
