Modify Plugin Code to Allow Stripe Installment Plan

Hey guys,
I’m looking to modify the PaidMembershipsPro plugin to allow me to set up an installment plan using Stripe as my payment processor. I received this email back from Stripe support recently, so I know it’s possible (and to give you a good idea of exactly what needs to be done):

Hey Matt,

Thanks for reaching out!

The Stripe API doesn’t currently have direct support for installment plans (i.e., “3 payments of $19.99”), however, you can certainly create this functionality with some custom code or a plugin. For your particular use case here’s one way you could handle things: after all of a user’s installments are paid, switch your user to a $0 a month subscription. That way they would not be billed but would continue on as members in your application.

Stripe allows ongoing membership plans OR installment and then membership cancellation (close to what I need, but then their access to content is removed), but what I need is an installment plan where afterward the user still retains membership access, so this would essentially be creating a plan that auto-switches a membership plan of $XX dollars a month after 4 months to a 0$ a month membership so they still retain membership.

Any idea how I could do this by modifying the plugin code? I know a thing or two, but I’m definitely not a pro at dissecting plugin code so not sure if I can handle this or if it’s way over my head and I should just hire someone.

Thank you for your help. ??

P.S. If you’re wondering, I have contacted PaidMembershipsPro but have yet to receive a response in about a week’s time, so reaching out here now.
