      Introduction

      Auto Debit payment is a payment solution that allows merchants to make pre-authorised fund deductions from a user's account.


      A user is first required to give consent to the merchant via a payment agreement, such as the three-party withholding agreement.


      When the user purchases items on the merchant's site again, the merchant can deduct funds from the user's account directly by using an authorization token.


      Subsequently, the merchant can use the token to initiate the auto debit payment request.


      #User experience

      This is an example user journey of a consumer who uses GCash to pay for products in Apple's App Store:

      This sample user journey assumes that the user has downloaded the GCash app:

      1. The user chooses a product priced at 1000 PHP in the App Store (merchant side), places an order, and chooses GCash as a payment method.
      2. The user is redirected to the GCash agreement page, where the authorization agreement is displayed.
      3. The user completes the authorization and returns to the App Store, where the authorization result and the linked GCash account is displayed.
      4. The user selects the GCash account to complete the payment. The App Store then returns the payment success result.
