I want to include PartPay as a third party integration widget to my enrolment form. How can I do this?

We do not have integration with PartPay so it is not possible to achieve that.

I can submit this as a feature request so it would be considered in the future.

For clarification, what features in PartyPay that you'd like to use in your form?

Can you give us any details on how you'd want it to work?
