At Last, I clasp: Escaping the G's Apps Script Copy-Paste Gauntlet

Short summary

Developer debugging a Chrome extension that syncs LinkedIn profiles to a Google Sheet via Apps Script encounters a 401 error and discovers a critical gotcha: the user interface says 'Anyone' can access it, but that actually means 'any logged-in Google user'—not truly public. The fix: changing a hidden code setting to 'ANYONE_ANONYMOUS.' Also introduces clasp, Google's command-line tool that automates Apps Script deployment and eliminates manual URL copy-pasting.

  • •Google Apps Script's 'Anyone' access control UI is misleading—it means 'any logged-in user,' not public; true anonymous access requires 'ANYONE_ANONYMOUS' in the code
  • •clasp CLI automates Apps Script deployment, version management, and URL updates in a single command
  • •Real debugging story showing how personal tools can be shipped cheaply using Google Workspace services
