Google Apps Script Autho Email


You may have received an email stating a failure of a Google Apps Script. In most cases it is due to a script (Program or application) that has not been executed (Triggered) for some time but now the authorisation to execute has expired.

The application could be a form on your website that visitors to your website used to make a booking or contact you. When the form is use and submitted by the visitor, a response email or calendar booking etc maybe processed. This process is completed by an application (program) that executes on your authority.

From time to time, these applications will require your permission to function, particularly after a long period of inactivity or changes to the application.

The reason for the script error in the email sample is "Authorisation is required" See #3. Basically, Google will only execute a script if you have given Google permission to do so by you.

This page outlines how to address the authorisation message.
