# Trigger Conversions with GTM

You can follow these detailed steps to set up Google Tag Manager (GTM) to trigger a Programmatic Conversion when a conversion event happens. This setup will involve creating triggers, tags, and potentially variables in GTM.

## Step 1: Define the Conversion Event in GTM

First, you must define what constitutes a "conversion" in your context. This could be a page visit, form submission, button click or any other user interaction.

## Step 2: Create a Trigger for the Conversion Event

1. **Go to Google Tag Manager Dashboard.**
2. **Click on 'Triggers' in the left sidebar.**
3. **Click 'New' to create a new trigger.**
4. **Set up the trigger:**
   * Choose a trigger type that matches your conversion event. For example, choose "Form Submission" for form submissions or "Click" for button clicks.
   * Configure the trigger with the necessary filters to capture your conversion event accurately. For example, if it’s a button click, you might need to specify certain button properties (like the button's ID or text).

## Step 3: Create a Custom JavaScript Tag

1. **Go to 'Tags' in the GTM dashboard and click 'New'.**
2. **Click 'Tag Configuration' and choose 'Custom HTML'.**
3. **Enter the custom JavaScript code:**

   ```html
   <script>
   // Call your custom function with the appropriate conversion ID
   optibaseSendConversionEvent('yourUserFriendlyConversionId');
   </script>
   ```

   Replace `'yourUserFriendlyConversionId'` with the actual ID or a variable that dynamically determines the ID based on the context of the conversion.

## Step 4: Add a Trigger to the Tag

1. **In the same 'Tag' configuration screen, click 'Triggering'.**
2. **Select the trigger you created in Step 2.**
3. **Save the tag.**

## Step 5: Test Your Tag

1. **Go back to the GTM main dashboard and click 'Preview'.**
2. **Navigate to your site where the conversion event can be triggered.**
3. **Ensure the tag fires when the event occurs. Check the output in the GTM preview pane to confirm that the custom JavaScript function is being called as expected.**

## Step 6: Publish Changes

Once you are satisfied that the tag is working correctly in the preview mode, go back to GTM:

1. **Click 'Submit' to create a new version.**
2. **Name your version and describe the changes.**
3. **Click 'Publish' to make your changes live.**

This setup ensures that every time the specified conversion event happens, your custom JavaScript function `optibaseSendConversionEvent` is called with the specified `userFriendlyConversionId`. Adjust the conversion ID dynamically using GTM variables if the ID should vary based on the conversion context.
