Acquirer host connections to the payment schemes have to adhere to payment scheme requirements. This is a pre-requisite before acquirers can get their terminal integration certification and start to perform transactions.

We at PayHuddle, help you test the processing of payment messages for speedy acceptance. This process can be lengthy and complex, as there are new rules and processes to obtain, understand and implement for every payment scheme. At PayHuddle, we have provided host validation services for 1000s of acquirers and processes across paymet schemes.

What do we do?
