Request's integration with Stripe allows you to accept cards as a payment option for your invoices. Once the card payment goes through, the invoice status is automatically updated to "Paid".
The scope of the Stripe integration is limited to payment acceptance at the moment. Notably, the integration does NOT support:
Creating invoices in Stripe each time you create an invoice in Request
Creating subscriptions in Stripe each time a recurrent invoices is generated in Request
Marking invoices in Request payable via Stripe as paid
Syncing data from Stripe to Request
