Hi Paypal,
Our payment processor was implemented accordingly to follow the document of Payflow Pro Transparent Redirect (https://developer.paypal.com/docs/classic/payflow/integration-guide/#introducing-the-gateway-checkou...). Everything work perfect in sandbox environment.
In production, I always got "Merchant Identification Error" response from https://payflowlink.paypal.com for transparent redirect transactions. Although the generate SECURETOKEN transaction was successful . I have checked almost everything of our manager account's settings:
- Allowed reference transaction is set to Yes
- IP whitelist is correct.
- Hosted Paypal Layout to Layout C (some people say this might cause the error but I don't think so. I have play with this setting in sandbox and it seems irrelevant).
Belows are request/response log of the test transaction in sandbox environment which is successful. I can't post the error log of production because it contains sensitive information.
