Hello,

Which endpoints using the REST API do I use to do the following:

1. create the invoice
2. add an line item for the plan our users choose
3. charge the credit
4. make it a recurring payment.
5. retrieve the invoice.

Is this possible? We’re using Keap Pro.

Thanks,  
Alain

It looks like you’ll be wanting to create a Subscription, which will then generate Orders per cycle. Billing is done automatically when each Order is created.
