Auto Debit Payment requires a user to sign a payment agreement (such as the three-party withholding agreement) with the merchant in advance. After that, when the user purchases merchandise on the merchant site, the merchant can deduct money from the user account directly by using an authorization token.

To use this payment solution, merchant needs to obtain the authorization in advance. Users need to sign a contract (such as the three-party withholding agreement) with merchant to authorize the merchant to obtain the authorization token. After that, the merchant can use the token to initiate the auto debit payment request.

  2. Louis is redirected to the GCash agreement page, where the authorization agreement is displayed.
  3. Louis completes the authorization and then returns to the App Store, where the authorization result and the linked GCash account is displayed.
