Custom Webhook (GHL)
also GHL webhook action · inbound webhook
GoHighLevel's workflow capability to send outbound HTTP requests to external URLs or receive inbound webhook triggers, passing JSON data between GHL and other systems.
Analogy
Like a phone line GHL uses to call out to other apps, or a number other apps call to reach GHL.
Why it matters
It's the main bridge connecting GHL automations to n8n, Make, Zapier, and custom APIs for anything native GHL can't do.
In practice
A workflow fires a custom webhook to an n8n endpoint, sending contact JSON to trigger an external enrichment flow.
