Api support for afform contribution pages
Afform what do we need to do to offer Contribution form
Contribution entity - but just basic fields Payment block
To do the latter we need an api like
PaymentForm with the actions
->submit
->getfields
->validate
payment_processor_id
would be required for each of these (getfields would reply with metadata that would indicate what additional fields are required)
That should be the minimum for a totally basic processor (like paypal std, paypalpro, dummy, payment express, Mollie, Sagepay recurring in Omnipay, some IATS)
All the complexity comes in when we start adding in the js - e.g Stripe, Paypal checkout, some IATS. I think it makes much more sense to get the easy ones working first - but once they are then for phase 2 we will need at minimum
- An api function to get the JS to add with some details about it
- A js object on the pay to return the total_amount from the form - this is something Matt has been working on & would need to be thought through across forms - eg. CRM.PaymentForm.getAmount() should do the same on the angular form and on the core civicrm forms. We probably need to articulate what other functions it may or may not need
On submission we would do
Order.create (this can just be the same params as Contribution.create in the initial submit. At minimum it is basically contribution.create with a forced ‘Pending’ status
PaymentProcessor.pay
Payment.create
These exist in apiv3 & I think we would use them for now
