# Retrieve Payment API
source: https://developer.mastercard.com/cross-border-services/documentation/api-ref/transaction-apis/retrieve-payment-api/index.md

Alert: If you are a Customer contracted with MTS EU or MTS UK, refer to the corresponding EU and UK specification inside the swagger file to ensure compliance with the relevant jurisdiction based on Regulatory Technical Standards (either EU or UK) derived from the Revised Payment Services Directive (PSD2).

You can use this API to retrieve the payment transaction using the transaction Id or transaction Reference.   
When using the Retrieve Payment API resource to check the status of a PENDING payment, it should be used no more than every 30 minutes for each payment being retrieved.
