Is there a way to run a google app script from a different app script?
im just getting into google app scripts and i couldnt find anything on the internet
It seems like you are looking for libraries functionality in Google App Script. Documentation
You can save a version of the script that you have the functions in it, and import the functions on to a second script file through menu>resources>libraries. You need to use script id for importing libraries, which you can find from menu>File>Project properties>Script ID
You can then execute the function using the script file name as the reference.
You can use the Apps Script API, you may find this helpful Executing Functions using the Apps Script API
"The Apps Script API provides a scripts.run method that remotely executes a specified Apps Script function"
You can call google app script form javascript or web page. You have to implement doGet(or post) and publish your google app script.
I found good example.
Cheers.
