Where can I find my Facebook pixel ID
You can add your Facebook pixel in your landing page Settings. Once it's done, you can view the conversion data in the Facebook pixel page in your Events Manager.
You can use already existing pixel if you have one set up already or create a new Facebook pixel by visiting your Business Manager Settings. If you haven't created your Business Manager account yet, you can do it by following this guide.
Once you've selected your Business Manager account, click on the Data Sources dropdown and select Pixels.
There, click Add, and you'll see a pop up to start creating your pixel. In there, you'll need to choose a name for your pixel and add your landing page URL.
Press Continue and on the next screen select Continue Managing My Business.
Then, you'll see your pixel ID. Make sure to copy it and paste it in the Facebook pixel ID box.
Once it's done, you can view the performance of your page in your Events Manager.
