The following figure illustrates the main workflow of Auto Debit, which focuses on how to bind a user account, complete a payment, and unbind the user account.
The main flow can be separated into several individual flows:
- Account Binding: To authorize the merchant to deduct funds from a user's account, the user must firstly bind his/her wallet account with the merchant, which is implemented by applying an access token.
- Payment: Once the user account has been bound, the merchant can initiate a payment request with the access token to deduct funds from the user's account when it is required.
- Token refreshing: To ensure that the access token regarding the authorization is valid and secure, the merchant and the Acquiring Service Provider can refresh the access token.
- Account unbinding: The user can unbind his/her wallet account from the merchant side or wallet side. Different interfaces need to be integrated for different unbinding sources.
