I am testing HPP payments and I follow the example code provided here in Developer portal. I have created an account on the portal and have found below information on my test app.
I always get These 2 errors.
506 Invalid MERCHANT_ID or ACCOUNT. Please contact the merchant. 508 Invalid data in MERCHANT_ID field. Please contact the merchant.
Merchant Id: MER_c4c0df11039c48a9b63701adeaa296c3
Below is my PHP code from the Server endpoint.
$config->merchantId = "MER_c4c0df11039c48a9b63701adeaa296c3";
$config->accountId = "internet";
$config->sharedSecret = "LYZIFACE9hHngwOy";
$config->serviceUrl = "https://pay.sandbox.realexpayments.com/pay";
