GoHighLevel OAuth2 Webhook Guide

When integrating tools like ClickUp or other external platforms, you may need to secure your custom webhooks with OAuth2 inside a GoHighLevel workflow. This step-by-step guide explains how to configure OAuth2 authentication for workflow webhooks so your data is exchanged safely with third-party APIs.

This tutorial is based on the official workflow OAuth2 custom webhook feature and walks you through each setting on the webhook configuration screen.

What Is OAuth2 in GoHighLevel Webhooks?

OAuth2 is a secure authorization method that lets GoHighLevel connect to another system without storing your username and password directly in the webhook. Instead, it uses tokens issued by the external service.

When you add a custom webhook to a workflow, you can choose OAuth2 as the authentication type. GoHighLevel then handles generating or refreshing tokens before sending the HTTP request to your target URL.

Typical use cases include:

• Sending contact or lead data from GoHighLevel to a third-party CRM or project tool.
• Triggering automations in external systems that require OAuth2 tokens.
• Keeping webhook calls secure without embedding static API keys.

Where to Configure OAuth2 in GoHighLevel

The OAuth2 options appear in the webhook step when you are building or editing a workflow in GoHighLevel.

At a high level, you will:

1. Create or open a workflow.
2. Add a Webhook action.
3. Set the webhook Method and URL.
4. Select OAuth2 as the authentication type.
5. Fill in the OAuth2 configuration fields described below.

Once configured, every time the workflow runs and reaches this step, GoHighLevel will obtain a valid access token and send the webhook according to your settings.

Key OAuth2 Options in GoHighLevel Webhooks

When you switch the authentication type to OAuth2 in your GoHighLevel webhook step, you will see several important fields. Each one controls how the system interacts with the external provider.

Authentication Type in GoHighLevel

Inside the webhook configuration, locate the Authentication Type dropdown. Select OAuth2. This tells GoHighLevel to use an OAuth2 flow instead of a simple API key or no authentication.

Token URL in GoHighLevel

The Token URL is the endpoint provided by the external platform where GoHighLevel will request or refresh access tokens.

• Copy the OAuth2 token endpoint from the external service documentation.
• Paste that URL into the Token URL field.
• Make sure it uses HTTPS for security.

Every time the workflow needs a token, it calls this URL using the method you specify next.

Token HTTP Method

The Method under the OAuth2 section determines how GoHighLevel sends the token request (for example, POST or GET).

Most OAuth2 servers expect a POST request for tokens. Confirm the correct method in the external provider's API documentation and select it in the dropdown.

Token Headers in GoHighLevel

The Token Headers area lets you define any custom headers needed by the external OAuth2 server.

Typical headers include:

• Content-Type: application/x-www-form-urlencoded or application/json
• Any custom headers required by the provider

To configure headers:

1. Click to add a header row.
2. Enter the header Key (for example, Content-Type).
3. Enter the header Value.

GoHighLevel will send these headers each time it calls the token endpoint.

Token Body in GoHighLevel

The Token Body defines the request payload that GoHighLevel sends to the token URL. This usually contains the fields required by the OAuth2 provider such as:

• grant_type
• client_id
• client_secret
• scope (if needed)
• refresh_token for refresh flows

In the webhook interface, you can build the body as key-value pairs or the format expected by the remote service. Follow the external service's documentation closely, since GoHighLevel will not validate these fields for you.

Including OAuth2 Token in the Webhook Request

Once a token is retrieved, you must tell GoHighLevel how to attach it to your final webhook call to the external API. This is controlled by the Include Token In option.

You can include the token in:

• Header – Common for Bearer tokens (for example, Authorization: Bearer <token>).
• Query Params – Adds the token as a URL parameter.
• Body – Embeds the token inside the request payload to the target endpoint.

Select the method required by the third-party API so the token is passed correctly by GoHighLevel.

Field to Store OAuth2 Token in GoHighLevel

The Field to Store OAuth2 Token specifies where in the token response GoHighLevel should look for the actual access token value.

Most OAuth2 providers return a JSON structure with a field such as:

• access_token
• token

Enter the exact key used in the provider's token response. GoHighLevel then extracts that value and uses it when sending the authenticated webhook request.

Step-by-Step: Creating an OAuth2 Webhook in GoHighLevel

Use the following checklist to configure an OAuth2-enabled custom webhook in a GoHighLevel workflow:

1. Open your workflow
   • Navigate to Workflows inside GoHighLevel.
   • Create a new workflow or edit an existing one.
2. Add a Webhook action
   • Click Add Action and choose Webhook.
   • Enter the target URL where you want to send data.
   • Choose the appropriate HTTP Method (GET, POST, PUT, etc.).
3. Enable OAuth2
   • Under Authentication, set Authentication Type to OAuth2.
4. Configure token request
   • Paste the provider's Token URL.
   • Set the token request Method (usually POST).
   • Define any needed Token Headers.
   • Build the Token Body with the fields required by the external API.
5. Map the token
   • Enter the Field to Store OAuth2 Token, such as access_token.
6. Attach token to the webhook
   • Choose how to Include Token In the final call (header, body, or query params).
   • If using headers, configure the header key (for example, Authorization) and the pattern (for example, Bearer <token>).
7. Test the workflow
   • Trigger the workflow with a test record.
   • Check the external system to confirm it receives the webhook with a valid token.

Best Practices for OAuth2 Webhooks in GoHighLevel

To keep your OAuth2 implementation stable and secure in GoHighLevel, follow these tips:

• Verify all token URL, header, and body values directly against the external provider's latest documentation.
• Use HTTPS endpoints for both the token URL and the webhook target URL.
• Store client IDs and secrets securely in your documentation; never share them publicly.
• Test with a non-production account or sandbox environment when available.
• Monitor API limits and refresh token policies for the connected service.
