Do you have a plug-in for Google Tag Manager?

Hi there,

I know you have a plug-in for Google Analytics, but do you have one I suppose something like this:

Really; however, I don’t specifically need a plug-in for GTM as such … mainly what I need is a means by which to copy and paste from Javascript straight after the opening <body> tags on every page within a site … the plug-in which would facilitate that, and the code would simply be a Google Tag Manager container code snippet (from which I can then deploy other Google Analytics tags, heatmaps and other tracking tools myself).

Love to hear your advice thank you!

Kind regards,
