Here, I would like to introduce a report for understanding the flow of the request to Web Apps created by Google Apps Script. There might be a case that various applications using the Web Apps are created and the Web Apps are used as the webhook. In that case, it is considered that when you have understood the flow of requests to the Web Apps, your goal might be able to be smoothly achieved. In this report, I would like to introduce the information about it.
As a sample situation, the sample script for the Web Apps is as follows. And, please set a Spreadsheet ID to work_. In this sample, the data from the request is put into the Spreadsheet. And, the event object is directly returned from the Web Apps.
