Email ID as query string parameter

[jamespapke]

Hello all - I can't seem to find this answer, so any help is appreciated. I'd like to automatically append the email id (marketo asset email id) to a query string parameter. As it's not available in the field list when creating an Email Script token, does that mean it's impossible? Thanks!

You can use the code here (which should be cross-posted to the official Products blog but I haven’t gotten around to it!).

Thank you, @SanfordWhiteman! I can't say I know exactly how this works even having ChatGPT explain it to me haha.  But with limiting the printed value to ${marketoSend.AssetId}, this works perfectly.

There is quite a lot of special sauce in there for sure.
