How to Create a Custom Conversion Event in Facebook

This guide explains how to create a Custom Conversion event in Facebook Events Manager using:

1️⃣URL Rules (for goal pages)
2️⃣ Event Parameter Rules (for Visiopt webhook)

Step 1: Open Events Manager

Go to your Facebook Ads account and open Events Manager, as shown in the screenshot.

Step 2: Go to Custom Conversions

In the Events Manager overview section, click on "Custom Conversions," as highlighted in the screenshot.

 

Step 3: Create a New Custom Conversion

Click the Create Custom Conversion button. 

A pop-up will open where you can enter the Custom Conversion details.

Step 4: Configure Rules
You can configure your conversion rule using either:
 

Method 1: Using URL Rules (for goal/confirmation pages)

Steps:

1. Select URL
2. Select Contains
3. Enter the URL or part of the URL used for your conversion goal
 

Example:

Full URL: https://ztrackingsystem.com/permission_live/confirmation-page

Partial URL: confirmation-page

IMPORTANT NOTE
The URL added in Facebook must match the URL (or partial URL) selected in the Visiopt Conversion API goal setup.

If these do not match, conversions will not be counted.

Method 2: Using Event Parameters (Visiopt Webhook)

Steps:

1. Select Event Parameters
2. In the text box, enter: event_name
3. Select Equals
4. In the next text box, enter the event name sent from Visiopt Conversion API — example: visiopt_lead

IMPORTANT NOTE
The event name entered must match exactly with the custom name value, because the same value is sent through the API event.

If the name does not match, conversions will not be counted.
 

Step 5: Save and Complete

Once you have entered all required details, click Create.

Your new Custom Conversion will now appear in the Custom Conversion list.

Step 6: Connect Custom Conversion in Visiopt

After the conversion is created, it will appear inside your Visiopt account.

You can now select this custom conversion while setting up the Conversion API
