Feature Request

User Story

As a user, I want to accept donation via payment intent API approach so that accepting donation via any payment method is a streamlined process.

Note: Currently, card payments are only supported with Payment Intent API.

Discussion with Stripe Developers

Question 1: using payment intent approach over traditional approach with Stripe elements js (https://stripe.com/docs/stripe-js) is recommended... right? or we can use both as per our convenience? What are your recommendations?

one doesn't replace the other, they are complementary. A payment intent replaces the concept of creating tokens/sources and charges yourself. You would still use Elements, just instead of creating a token/source and sending to your backend to charge, you call handleCardPayment(https://stripe.com/docs/stripe-js/reference#stripe-handle-card-payment) with your payment intent, and we complete the charge for you using the information in the Element right now I'd 100% recommend integrating against payment intents for accepting card payments(it makes it much much easier to accept 3D Secure transactions, which is really important with upcoming EU regulations), and we'll expand intents over time to support other methods

Question 2: any other benefits for payment intent for accepting card payments?

the 3D Secure one is the main one, as that will be huge this year. Also, it's the only thing we're going to be recommending going forward, payment intents will be the new abstraction for accepting payments with Stripe and will tie into all our other products so it's worth integrating them now.

As per the discussion with @DevinWalker, we agreed to start implementing the payment intent API so that our stripe core and its add-on will follow all the SCA regulations coming in Europe on 14 Sept 2019.

Note: Currently, Payment Intent API supports card payment type which includes onsite CC payments, offsite CC payments (i.e. Stripe Checkout ), and Payment Request (i.e. Apple/Google Pay) as per the documentation here https://stripe.com/docs/payments/payment-intents/migration

Slack Call Summary

Participants: @mehul0810 @ravinderk
Topic: Discussion on payment intent donation processing workflow.
Result: I showed the workflow of the donation processing using payment intent and it seems that the process is perfect to go with as discussed with Ravinder. However, I will show a demo on dev call tomorrow to discuss it further tomorrow.

Closing this issue as this feature is implemented and is working fine with branch issue/4010 with one time donations for Stripe CC as well as Stripe Checkout. Class for payment intent implemented is extensible to use in Stripe premium.
