Dictionary term
Custom Webhook (GHL)
Also called GHL webhook action · inbound webhook
GoHighLevelAdvanced
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.
In plain English
Custom Webhook is the HighLevel workflow step that sends contact data to another app's URL. Inbound Webhook is the matching trigger for receiving data.
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.
