In-depth guide

Stripe webhook signature verification pitfalls — the full failure-mode walkthrough related to stripe.com, checked against official docs, with linked verified routes.

Steps

  1. POST /v1/payment_intents with payment_method_types=["affirm"], amount, currency=usd (Affirm is USD-only on Stripe), and capture_method=automatic
  2. Affirm requires shipping address details; attach the shipping object to the PaymentIntent or PaymentMethod with name, address, and phone
  3. Create a PaymentMethod with type=affirm and billing_details; then confirm the PaymentIntent with return_url
  4. Redirect the customer to next_action.redirect_to_url.url; the customer completes the Affirm loan application and approval in Affirm's hosted flow
  5. On redirect return, check PaymentIntent status; succeeded means Affirm approved and funds are guaranteed; capture_method=automatic is typical since Affirm manages the loan disbursement timeline
