The Retrieve Countries service allows the issuer to retrieve available countries on the Priceless Specials API.

Upon successful request for retrieval of the countries, the issuer may use the country codes to further fine-tune their requests for offers, programs, or benefits from the Priceless Specials API.

## Pre-requisites {#pre-requisites}

Before using the Priceless Specials API service, your project must first be created as an API project on the Mastercard Developers.
