How to Use Outbound Webhooks in GoHighLevel Workflows

GoHighLevel workflows let you send data to other tools such as ClickUp, CRMs, or custom apps using outbound webhooks. This guide explains, step by step, how to configure the webhook action so you can integrate external services and APIs efficiently.

The instructions below are based on the official webhook workflow action documentation and will help you set up and test outbound requests correctly.

What Is the GoHighLevel Webhook Workflow Action?

The webhook action in a GoHighLevel workflow allows you to trigger an HTTP request to an external URL whenever a contact enters that step in the workflow. This is useful for:

  • Sending contact data to another system
  • Triggering automations in external tools
  • Syncing information between GoHighLevel and third-party apps

Each time the workflow reaches the webhook action, GoHighLevel sends a request to the configured endpoint using your selected HTTP method and payload.

Where to Find the Webhook Action in GoHighLevel

Before configuring details like method or headers, you must locate and add the webhook step in your automation.

  1. Open your GoHighLevel account and go to Automation.
  2. Select the workflow where you want to send data externally.
  3. Click Add New Action in your workflow canvas.
  4. From the action list, choose Webhook.

After selecting the webhook action, a configuration panel will appear so you can define the request details, such as URL, method, headers, and body.

Configuring the Outbound Webhook in GoHighLevel

Once the webhook action is added, you must set up the basic connection information. These fields control where the data goes and how it is sent.

1. Webhook URL

The Webhook URL is the endpoint that will receive data from your GoHighLevel workflow.

  • Enter the full URL provided by the external service or your custom API.
  • Make sure the URL uses https:// if the receiving system requires SSL.

Every time the workflow hits this step, GoHighLevel will send a request to this URL.

2. HTTP Method

The HTTP Method determines the type of request GoHighLevel will send. The available methods typically include:

  • POST – Most common for sending data to APIs.
  • GET – Often used to retrieve data or trigger simple endpoints.
  • PUT / PATCH – Used for updating data where supported.
  • DELETE – Used when you need to remove data via an API.

Choose the method your external service specifies. For most integrations, you will use POST.

3. Headers

Headers allow you to send additional information with your webhook request. In the GoHighLevel webhook configuration, you can add custom headers in key-value format.

Common examples include:

  • Content-Type: application/json or application/x-www-form-urlencoded
  • Authorization: API keys or bearer tokens required by your external system

Add only the headers specified by your endpoint documentation. Incorrect headers can cause the receiving service to reject the request.

4. Request Body

The body contains the data you want to send from your GoHighLevel workflow to the external endpoint.

In the body field you can:

  • Enter static values (e.g., fixed parameters or codes).
  • Use contact and workflow custom values/merge fields.

Common data to send includes:

  • Contact name, email, and phone
  • Pipeline or opportunity data
  • Tags, custom fields, and other attributes

Ensure the body structure matches what the receiving API expects (for example, properly formatted JSON or form-encoded data).

Using Custom Values in GoHighLevel Webhooks

One of the most powerful features of the GoHighLevel webhook action is the ability to embed custom values, which allows you to send dynamic contact data.

When configuring the body or headers:

  • Click inside the field where you want dynamic data.
  • Select available Custom Values from the dropdown, such as contact details or workflow data.
  • GoHighLevel will automatically replace these placeholders with live values when the workflow runs.

This lets you build flexible integrations without hard-coding specific information.

Testing Your GoHighLevel Webhook Action

After you configure the webhook URL, method, headers, and body, you should test that the request is working as intended before sending live traffic.

Step-by-Step Testing Process

  1. Save your workflow with the webhook action configured.
  2. Enroll a test contact into the workflow, or manually add a contact to the specific step.
  3. Trigger the workflow so it reaches the webhook action.
  4. Check the receiving service or your API logs to confirm the request was received.

If your external tool supports it, you can also use a test endpoint to inspect the raw webhook payload that GoHighLevel sends.

Verifying Responses and Errors

Depending on the design of the platform, the webhook action may log response codes or error messages. Use this information to troubleshoot:

  • 400 or 500 errors usually indicate an issue with the body, headers, or endpoint.
  • 401 or 403 errors often mean your authorization header or API key is incorrect.
  • 404 errors show that the endpoint URL is wrong or missing.

Update your settings based on the error details, then repeat the test until the request completes successfully.

Best Practices for GoHighLevel Webhook Workflows

To keep your automations reliable and scalable, follow these best practices when using the GoHighLevel webhook action:

  • Document your endpoints: Keep notes on which workflows send data to which URLs and why.
  • Use test contacts: Never test on real customers when first setting up or modifying a webhook.
  • Limit unnecessary data: Only send the fields the external system truly needs.
  • Secure your endpoints: Use HTTPS and authentication tokens whenever possible.
  • Monitor changes: If an external API changes, update your GoHighLevel configuration immediately.

When to Use GoHighLevel Webhooks vs. Native Integrations

If a direct, native integration already exists between GoHighLevel and your target app, you may not need a webhook. However, outbound webhooks are ideal when:

  • No official integration is available.
  • You are connecting to a custom internal system.
  • You need very specific data structures or logic not covered by built-in apps.

Evaluate your integration needs first, then decide whether a webhook workflow action or a native connector is the better fit.
