Webhook

A webhook is a user-defined HTTP callback — system A POSTs to a URL on system B the moment an event happens — the simplest way to make integrations real-time.

What is a webhook?

A webhook is a way for one system to notify another the moment an event occurs by POSTing a JSON payload to a configured URL. Where polling means "ask every minute if anything changed," a webhook means "I'll push you the change the instant it happens." Lower latency, less load, simpler design.

Why it matters

Real-time integrations without streaming infrastructure
Drives every "speed to lead" play (form submit → instant routing)
The default integration mechanism in modern SaaS

Webhook best practices

Always verify signatures — webhook URLs are public; signatures prove the sender
Respond fast (200 OK) and process async — don't make the sender wait for your downstream work
Idempotent handlers — webhooks may be retried; the same payload may arrive twice
Log everything — debugging a misfiring webhook is hard without payload history

How TexAu helps

Trigger any TexAu workflow from a webhook for instant enrichment, scoring, and routing — and emit webhooks back out the moment a workflow completes for downstream consumers (Slack alerts, CRM writes, sequencer kickoff).
