Mintlify uses access tokens and webhooks to authenticate and sync changes between GitLab and Mintlify.

- Mintlify uses access tokens to pull information from GitLab.
- GitLab uses webhooks to notify Mintlify when you make changes, which enables preview deployments for merge requests.

## Set up the connection

When you open [Git Settings](https://app.mintlify.com/settings/deployment/git-settings) for the first time, a setup wizard guides you through connecting your GitLab repository.

<Steps>
  <Step title="Select GitLab as your provider">
    On the [Git Settings](https://app.mintlify.com/settings/deployment/git-settings) page, click **Connect to GitLab** and then click **Continue**.
  </Step>
  <Step title="Download your content">
    <Tip>
      If you already have a GitLab repository with your documentation, you can skip the download and click **Continue setup** directly.
    </Tip>
    
    If your documentation is hosted by Mintlify, download it as a zip file.
    * Create a new repository in GitLab.
    * Extract the zip contents.
    * Push the contents to your repository.

    Click **Continue setup** to proceed.
  </Step>
  <Step title="Find your project ID">
    In your GitLab project, navigate to **Settings** > **General** and locate your **Project ID**.

    </Frame>
  </Step>
  <Step title="Generate an access token">
    Navigate to **Settings** > **Access Tokens** and click **Add new token**.

    Configure the token with these settings:
    - **Name**: Mintlify
    - **Role**: Maintainer (required for private repos)
    - **Scopes**: `api` and `read_api`

    Click **Create project access token** and copy the token.

    <Note>
      If Project Access Tokens are not available, you can use a Personal Access Token instead. Personal Access Tokens expire, so you must update them when they do.
    </Note>

    </Frame>
  </Step>
  <Step title="Connect your repository">
    Back in the setup wizard, fill in the following fields:

    - **GitLab instance URL**: Leave blank for `gitlab.com`, or enter your self-hosted instance URL (for example, `https://gitlab.your-domain.com`). Your instance must be publicly accessible for Mintlify to reach it.
    - **Project ID**: The project ID from your GitLab project settings.
    - **GitLab deployment token**: The access token you generated.
    - **Branch**: Select the branch to deploy your documentation from.

    Click **Connect**.

</Steps>

## Update an existing connection

To modify your GitLab connection settings after the initial setup, go to [Git Settings](https://app.mintlify.com/settings/deployment/git-settings) and update your project ID, access token, branch, or instance URL directly.

## Revalidate Git settings

If your deployment shows unexpected behavior, such as missing branch options or stale configuration, you can force Mintlify to refresh your Git source.

<Steps>
  <Step title="Navigate to Git Settings">
    Go to [Git Settings](https://app.mintlify.com/settings/deployment/git-settings) in your dashboard.
  </Step>
  <Step title="Revalidate your settings">
    Click the green **Active** badge in the corner of the GitLab settings box to revalidate your Git source.
  </Step>
</Steps>

## Create the webhook

Webhooks notify Mintlify when you push changes so that deployments trigger
automatically.

<Steps>
  <Step title="Add new webhook">
  1. In GitLab, navigate to **Settings** > **Webhooks**.
  2. Click **Add new webhook**.
    <Frame>
      <img src="/images/gitlab/gitlab-webhook.png" alt="Screenshot of the Webhooks page in the GitLab dashboard." />
    </Frame>
  </Step>
  <Step title="Set up URL and webhook">
    Name the webhook **Mintlify**.

    In the **URL** field, enter the endpoint `https://leaves.mintlify.com/gitlab-webhook`.
  </Step>
  <Step title="Get the webhook token">
    In your Mintlify dashboard, click **Show webhook token**. Copy the webhook token.

      <img src="/images/gitlab/show-webtoken-dark.png" alt="Screenshot of the GitLab connection in the Mintlify dashboard." className="hidden dark:block" />
    </Frame>
  </Step>
  <Step title="Paste the webhook token">
    In GitLab, paste the webhook token from your Mintlify dashboard in the **Secret token** field.
  </Step>
  <Step title="Select events">
    Select the following events to trigger the webhook:
    - **Push events** (All branches)
    - **Merge requests events**
  </Step>
  <Step title="Verify the webhook">
    You should see the following settings after configuring the webhook:
    
    - **Name**: Mintlify
    - **URL**: `https://leaves.mintlify.com/gitlab-webhook`
    - **Secret token**: The webhook token from your Mintlify dashboard
    - **Events**: **Push events** (All branches) and **Merge requests events**

    Add the webhook.

    </Frame>
  </Step>
  <Step title="Test the webhook">
    After you create the webhook, click the **Test** dropdown. Click **Push events** to send a sample payload. If the test returns `Hook executed successfully: HTTP 200`, you configured the webhook correctly.
