GoCardless Integration

I have a project at the moment where I am developing a membership portal for a rugby club and they wish their members to pay for membership via the GoCardless service (https://gocardless.com).

I hoping there is someone in the community that can help with the integration of GoCardless into the portal I am building. I am using RapidWeaver and PHP for this project.

GoCardless have a PHP API which can be found here - https://gocardless.com/features/api/.

Many thanks,
