Webhook
Visual walkthrough
Follow the money, not the button
$48
Your app
Provider
Your server
browser redirect
webhook
01Your server prices the order
02Customer lands on the provider's page
03Card charged by the provider
04Provider tells your server, server to server
05You mark it paid and grant access
You never touch a card number. You describe the order and wait to be told it worked.
The reverse of an API call: another company's server telling yours that something happened.
Interactive demo
Checkout, end to end
Press Buy. Watch the thin grey redirect and the heavy green webhook — they are not the same promise.
