Hello community, I am Hyunjoe Yoo, a Software Developer in the DevRel Team at Mastercard.
Encryption is a method to protect sensitive information such as personally identifiable information, credit card numbers, and more. Its application could be expanded to API when handling sensitive data, so the body of the request could be encrypted.
Mastercard provides encryption helper libraries in different languages (Java, Python, Node, Ruby, C#, PHP and Go) to help you do this in code. You can find them here.
But if you want to quickly test out an API through Postman, you can’t use/import these helper libraries directly into Postman.
Please refer to How to implement encryption in postman for more information with a video that walks you through the basics of creating a project in Mastercard Developers, getting the consumer and authorization keys and how to plug them into Postman. It is a great guide that shows how to import a script into Postman, which encrypts/decrypts the request/response bodies as well as how to configure it to use the correct keys.
