Webhook
A reverse API call: instead of your system asking a service for updates, the service sends an HTTP request to your endpoint the moment something happens — a payment succeeds, a document is signed, an order ships.
Why it matters
Webhooks replace polling, so data arrives in seconds instead of minutes and you stop paying for thousands of empty requests. Most payment, messaging, and CRM integrations depend on them.
How we approach it
We verify signatures, make handlers idempotent so a repeated delivery cannot double-charge a customer, and queue incoming events, so a slow internal process never causes the provider to mark your endpoint as dead.
