I have written an Apps Script for personal use that I want to invoke with an HTTP request. (I'm basically using this like a "serverless function" with native authentication to Google Apps APIs.)
I can do this easily by deploying my Apps Script project as a Web App, which gets me a URL like
https://script.google.com/macros/s/${DEPLOYMENT_ID}/exec
However, if I make changes to my script and want to push those changes live, I have to create a new deployment, which will have a new deployment ID, thus changing the URL.
I know that I could use a "Test Deployment" to get a URL that always points to the project HEAD, but this always requires authentication from the HTTP client. With my deployment, I can set "Who has access" to "Anyone" and avoid this requirement.
Is it possible to deploy a web app script to a URL that will not change on future deployments?
