mle - invoices and emails

Do you mean an invoice email? Those only apply to collection_method=send_invoice:
https://stripe.com/docs/invoicing/integration/workflow-transitions#emails

So if you're using automatic payment then no the /pay endpoint would not cause an invoice email to be sent (though perhaps it will lead to a payment receipt email, if you have that enabled)

Could you share more about this payment receipt email setting?

if collection_method=send_invoice, can I still "pay" that invoice manually (call Stripe::Invoice.finalize_invoice and Stripe::Invoice.pay?

[calm canyon]

Yep, docs around that are here: https://stripe.com/docs/receipts#receipts-with-billing
and the setting can be found here: https://dashboard.stripe.com/account/emails

Yes!

If you collect payment details yourself, you can use a suitable payment method attached to your customer to pay an emailed invoice
