How to Use Custom Webhook Workflow Actions in GoHighLevel

ClickUp users and digital agencies often need to pass data between tools, and GoHighLevel provides a flexible way to do this with custom webhooks. This step-by-step guide explains how to configure and use the custom webhook workflow action so you can send contact and event data to external services and APIs reliably.

The instructions below are based on the official documentation for custom webhooks and focus on practical, repeatable steps that any GoHighLevel account admin can follow.

What Is a Custom Webhook in GoHighLevel?

In GoHighLevel, a custom webhook is a workflow action that sends data from your account to an external URL. When a contact enters a workflow and reaches this action, the system triggers an HTTP request to the destination you define.

Typical uses include:

  • Sending contact details to external CRMs or databases
  • Triggering third-party automation platforms
  • Updating external reporting systems
  • Notifying custom-built apps about new leads or events

The custom webhook action works inside workflows, so it can be combined with other actions and conditions to build powerful, automated processes.

Where to Find the Custom Webhook Action in GoHighLevel

You must first access the workflow builder in your sub-account. From there, you can add the custom webhook as one of the steps.

  1. Log in to your sub-account.
  2. Navigate to Automation and open Workflows.
  3. Create a new workflow or open an existing one.
  4. Click the + button to add a new action.
  5. Select the Webhook or Custom Webhook action from the list.

After adding the action, the configuration panel will appear on the right side, where you can set the details of your custom request.

Configuring a Custom Webhook in GoHighLevel

The configuration of the webhook action determines how GoHighLevel communicates with the external service. You need to provide the URL, HTTP method, and any optional data or headers required by the receiving system.

Core Settings for GoHighLevel Webhooks

When you add the custom webhook action, you will see these primary options:

  • Request URL – The endpoint of the external service that will receive the data.
  • Method – The HTTP method used to send the request, such as POST, GET, PUT, or PATCH.
  • Body Type – The format of the data sent in the body, typically JSON or form data, depending on the receiving API.

Make sure you obtain the correct URL and requirements from the documentation of the external service or API before configuring the webhook action.

Adding Headers and Authentication

Many APIs require authentication headers or custom values. The custom webhook action in GoHighLevel allows you to add header key-value pairs.

  1. Locate the Headers section in the webhook configuration panel.
  2. Click to add a new header.
  3. Enter the header key, such as Authorization or Content-Type.
  4. Enter the corresponding value, such as a bearer token or API key as required by the service.

Common header examples include:

  • Content-Type: application/json
  • Authorization: Bearer YOUR_API_TOKEN

Always keep sensitive tokens secure and only share them with trusted systems.

Defining the Request Body

When using methods like POST or PUT, you can send a request body from GoHighLevel to the external endpoint. The body can include both static values and dynamic fields from the contact or workflow.

Typical steps:

  1. Select the desired body type, usually JSON.
  2. Enter the structure required by the API, such as JSON key-value pairs.
  3. Use the field selector to insert dynamic data from the contact record, such as name, email, or phone.

For example, a JSON body might look like:

{
  "name": "{{contact.name}}",
  "email": "{{contact.email}}",
  "phone": "{{contact.phone}}"
}

This structure allows the receiving system to store or act on values from GoHighLevel every time the workflow runs.

Using Dynamic Data Fields in GoHighLevel Webhooks

The power of the webhook action comes from merging dynamic data fields into your request. This ensures each request contains information from the individual contact who triggered the workflow.

You can insert values such as:

  • Contact details (name, email, phone, address)
  • Custom fields defined in your account
  • Pipeline or opportunity information
  • Appointment details and status

To add a field:

  1. Place the cursor where the value should appear.
  2. Open the dynamic fields menu in the editor.
  3. Select the appropriate contact, custom, or system field.

These fields will be replaced with actual values at runtime when GoHighLevel executes the workflow for each contact.

Testing and Troubleshooting GoHighLevel Webhooks

Before relying on a webhook in a live automation, you should test it thoroughly. This minimizes errors and ensures the receiving service gets the exact format it expects.

Running a Test Through the Workflow

To test your webhook setup:

  1. Create a test contact with valid data.
  2. Manually add the test contact to the workflow or trigger the workflow conditions.
  3. Allow the workflow to progress until it reaches the custom webhook action.
  4. Check the external service or logs to confirm the data was received.

If the external service supports logs, verify the status code, headers, and payload. You should see the proper values for all mapped fields from GoHighLevel.

Common Webhook Issues and Fixes

If the webhook does not behave as expected, consider these potential issues:

  • Incorrect URL – Confirm the endpoint exactly matches what the external service requires.
  • Wrong HTTP method – APIs may accept only specific methods such as POST for data creation.
  • Missing headers – Many APIs reject requests that lack authentication or proper content type.
  • Invalid JSON structure – Extra commas, missing quotes, or incorrect nesting will cause failures.
  • Empty dynamic fields – If required contact fields are blank, the receiving system may reject the request.

Adjust the configuration, then run new tests until requests consistently succeed.

Best Practices for Reliable GoHighLevel Webhooks

To build stable automations, follow these best practices when using custom webhooks:

  • Document each external endpoint, required fields, and headers.
  • Standardize naming of custom fields used by webhooks.
  • Create separate workflows for testing before deployment.
  • Monitor responses in the external system whenever you adjust mapping.
  • Use secure tokens and rotate them when required by your external service provider.

These habits help keep your GoHighLevel workflows scalable and easier to maintain for teams and clients.
