Type of Change
Description
Integrate Dwolla connector
Added ACH bank debit flow.
Flow
Customer Creation - We create a customer using their email ID and receive the customer ID in the response headers.
Payment Method Token (PMT) - We use the customer ID and bank account details to create a funding source.Receive the funding source ID in the response headers.
Handling Duplicate PMT Errors - When a subsequent request is made with the same bank account details, the connector returns a 4xx error along with the existing funding source ID in the error response.
To handle this scenario:
Payments Flow
Refunds Flow
Since the connector does not support native refunds, we reverse the direction of payment to simulate a refund.
Note : In the Dwolla Sandbox environment, payment (transfer) statuses do not automatically change to "success" (or "processed") for bank-sourced transfers. By default, these transfers will remain in the "pending" state indefinitely, as the Sandbox does not replicate real ACH processing.
