## 1. Send the retrieve payment instruction request. {#1-send-the-retrieve-payment-instruction-request}

Alert: The Mastercard assigned ICA is used for agent identification in all service requests for core operations. A customer service provider can use their API credentials to transact on behalf of a customer by providing their customer's ICA number in the request. Direct payment agents can still transact by entering their own ICA when sending a transaction to Mastercard Track Business Payment Service.
API Reference: `GET /buyer-payment-agents/{ica}/payment-instructions/{transaction_id}`

## 2. Review the possible error codes associated with the request. {#2-review-the-possible-error-codes-associated-with-the-request}

You may receive the following statuses from Business Payment Service throughout the A2A payment instruction flow.
