HighLevel Inbound Webhooks

Inbound webhooks are part of HighLevel's Premium Workflow Actions. Shaun Clark walked through this feature on launch day, and the idea is simple: something happens in an external system, that system sends data to HighLevel, and HighLevel does something with it.

It could be a digital event in another piece of software, or something physical like a purchase in a store — doesn't matter. If it can send an HTTP request, HighLevel can receive it and act on it.

Setting It Up

1. Go to Automations and create a new workflow
2. Add a trigger → select Inbound Webhook
3. HighLevel generates a unique POST URL — copy that
4. Point your external system at that URL
5. Send data as a JSON body in the POST request

When data comes in, HighLevel maps it to contact fields. So if your JSON body includes name and email, you can use those values to create or update a contact, set the internal source to "inbound webhook," and kick off any workflow actions from there.

Testing with Postman

Postman is free and makes this easy to test:

1. Create a new POST request
2. Paste your webhook URL
3. Add a JSON body with test data (name, email, whatever you're sending)
4. Hit Send

You'll see the contact appear in HighLevel immediately with the data you sent.

What You Can Do With the Data

The webhook data isn't limited to contact creation. You can use the values from the body in:

• Create/Update Contact actions — map webhook fields to HighLevel fields (email, phone, custom fields)
• Emails and SMS — reference webhook values directly in your message content
• Conditional branches — route the workflow based on what data came in
• Google Sheets lookups — use webhook data to query spreadsheets

If you change or update your JSON body later, you can update the mapping references without rebuilding the workflow.

When You'd Use This

• An e-commerce platform sends order data → HighLevel creates a contact and starts a follow-up sequence
• An external form tool sends submissions → HighLevel captures the lead
• A custom app or N8N workflow sends event data → HighLevel triggers an automation
• Anything that can make an HTTP POST request → HighLevel can receive it
