Retrieve Installment Plans - Getting error 9201 Token Validation Failed

[EricEng]

Hi Support Team,

I'm facing an issue on retrieving VISA installment Plan with using Postman, Error 9201 Token Validation Failed

Endpoint: https://cert.api.visa.com/installments/v2/plans/match

I'm using the X-Pay-Token authentication method. For field encryption I'm using sample code "EncryptionUtils" by passing the APIKey and SharedSecret under Dashboard->Credential->X-Pay-Token, with payload "4111222233334444"

string xToken = getXPayToken("installments/v2/plans/match", "apiKey=API_KEY",
@"{""encAccountNumber"": ""eyJhbGciOiJIUzI1NiIsImtpZCI6ImQ0MjgzOGM3LWI2YTgtNDBhNy1hNmM4LTEwMjc5NjEwZmZmYSIsInR5cGUiOiJKT1NFIiwiY3R5IjoiSldFIn0.ZXlKaGJHY2lPaUpCTWpVMlIwTk5TMWNpTENKcGRpSTZJbmcyUVVaWVIza3lkalJqVGxFeWREWWlMQ0owWVdjaU9pSkdVSFY2WkZKTlJpMHhkV0ZoWHpKdGNsQndlbVJSSWl3aVpXNWpJam9pUVRJMU5rZERUU0lzSW10cFpDSTZJa0pWVWpCWFNFcGFNVEZTVlZWRVV6aEZORFZUTVROa2JWQTVZbmh0YzFWeVZEQmlSWEJHVG1wWVRuTXlaa1ZpZDNNaWZRLkdMbWtfM1RKS2UxajlIX1hCSERPUnQwZ1JsY19LTXJmQ3psU0tObFBZUFEuX1FfYjVLWnRVWUFkYWtXWC4yQ2p1NXA0WXRMTkxXeHhGUlVYZVVnLmpYNk5KTXNOQnJrSHZRRDdjT2NVZnc.AL8qBppOHX9t5NL1Vkr07fKIb0q4vaA1kaa_6hk32Qw""}");

I had tried to called the HelloWorld endpoint and it respond successfully

Kindly let me know if I'm missing out anything.

Thanks in advance.
