How to set up Facebook analytics in Google Tag Manager for Android

Question

I am using Google Tag Manager for sending analytics to various channels like Google Analytics. Now I want to send analytics to Facebook as well but I could not find any way to do so.

PS: The question is for Android app not for website. I had found multiple ways to send events to Facebook for website like: https://www.advertisemint.com/install-facebook-pixel-google-tag-manager/

I have tried to do so for Android Container as well but it does not have CustomHtml option while creating Tag. I think their might be some different approach for this.

Answer 1

If you want to use GTM in order to send events to FB analytics, you'll have to select "function call" when creating your tag in GTM. At this time, you'll have to populate the key-value pairs that you want to be in the payload your app will receive. You'll also have to reference a class which will handle this tag. This class will implement from com.google.android.gms.tagmanager.CustomTagProvider. Here is how a simple tag looks like in our GTM interface :

I helped to develop a connector called Cargo for my company, which helps to collect analytics through different platforms on mobile apps. Do not hesitate to take a look at it, or even to adopt it, and to pull some changes if you want to ! :)

1. Here is our class Tags which handles the custom function calls set in GTM.
2. Then we route the call to the selected handler/connector, depending on a parameter in the payload given by the container. This method does the job.
3. Last, but not least, we route the call to the correct method of the selected handler/connector, which receives the payload with all the parameters you set in your GTM interface.

I hope this helps !
