Webhook automation
Triggering workflows from HTTP callbacks the moment events happen — a payment, a form, a commit — instead of polling on a schedule. Webhooks are the event backbone of most integration work.
Events instead of polling
A webhook is an HTTP callback fired by the source system the instant something happens — a payment settles, a form is submitted, a commit lands. The alternative is polling on a schedule, which is slower, wastes calls on a mostly unchanged world, and still misses things between intervals.
What production webhooks demand
Verify the signature, because an open endpoint is an invitation. Respond immediately and process asynchronously, because senders time out. Expect duplicates and make handling idempotent, because at-least-once delivery is the norm. And return a non-2xx on genuine failure so retries actually happen.
The natural trigger for an agent
Webhooks pair well with agent steps because the arriving payload is often exactly the ambiguous, variable input that fixed rules handle badly. The event says something happened; the agent decides what it means and what should follow.
In AGNT
AGNT workflows expose webhook triggers, so any system that can POST can start verified agent work.
Webhook automation — common questions
How do I verify a webhook is genuine?
Check the signature header against the shared secret before doing anything else, and reject anything that fails rather than processing it cautiously.
What if my endpoint is down when the event fires?
Most providers retry with backoff. Design for duplicate delivery, and reconcile against the source periodically for anything critical.
Can AGNT receive webhooks?
Yes. Workflows expose webhook triggers, so any system able to POST can start verified agent work.
