Here's how you can get it:

Open the Google Tag Manager account and click on "Start for free". You will be prompted to enter your Google account information.

Once inside your Tag Manager account, click on the button that reads "Create Account". This is for you to create a new pixel code, not a new account itself.

You will need to enter the required information about your website or URL to correctly generate the code. Once everything is set, simply click on the "Create" button.

A new pop-up will appear and you have to accept the Terms and Conditions by ticking the box and clicking on the "Yes" button

Next, you will see your Tag account for the website or URL you've entered. A pop-up will emerge and this is where you will copy the Pixel code from and paste it on your Pixelfy account.

Finish setting up your Tag Manager Pixel on Google and you should be good to go!
