The Account Management Flow is the subsequent process that follows a successful registration.
Here's an overview of how the account management flow operates:
The process begins when a customer in the merchant application initiates the flow by sending a request with VPA suggestions to the Payment Service Provider (PSP) using the FetchAccounts API.
The PSP, in turn, sends a request by triggering the ReqListAcc API to the National Payments Corporation of India (NPCI). The NPCI processes the request and sends the response back to the PSP.
The Add Account API is then utilized to link the customer's bank account to a VPA with a one-to-one mapping or to multiple VPAs with a one-to-many mapping. If the VPA does not already exist, it will be created during this step.
