Hello, I need an payment gateway expert to create one external gateway (on a different domain) which I can use on several other wordpress websites where I sell services with Gravity Forms. The idea is to redirect all payments coming from many other domains to 1 domain which contains the gateway.
For example: [login to view URL] (all payments from [login to view URL], [login to view URL] etc. should go through this gateway domain)
You need experiences in Gravityforms and Paypal for this job.
