how to put the dynamic url variable of a button?

[vandrovisky]

hello everybody. How can I send the variable {{1}} from a dynamic url using Send Template?

Hello, just leave it as you have it.
just send the parameter and it will be added to the end of your dynamic url.

It is not necessary to put {{1}}

Thanks for your help identifying that the sub_url was missing from my code through your example!
Thank you very much!!
