PayFast payment gateway - Error: 400 Bad Request

I am using the PayFast payment gateway and I have run into a huge problem. PayFast requires that you have a passphrase in your signature in order to enable subscriptions (repeat payments). There is no space to do that in the Payfast Plugin for OS Service Booking.


The following information provided by the seller is invalid:
signature: Generated signature does not match submitted signature.

Need urgent solution

The PDT integration method is deprecated and will be discontinued by 2018-12-31 Payfast now needs a passphrase

Hi Wynand,
Please submit ticket on category: OS Services Booking and provide your site url with super admin account. I will figure the cause of issue for you
Thanks
