How To Insert Snapchat Conversion Tracking Code In 4.7.2?

Dear members,

I am trying to add a Snapchat conversion tracking code to my site but I do not know where to add it, can someone please let me know about this?

I want to add it on all pages

Your comments as always will be highly appreciated

Look at how things ar done for Google and other sites. Simply use the index:scripts.post.tpl hook to either add your script or to reference it from the js directory.
