Makes a Google Sheet Into a Public GET API (for reading and writing)

The example we use is a simple one column sheet which can be read in json output and written to append to the last line.

Steps

Create the column and add data. (for example - "Users" as the header, "Bob" as first row (A2) and "Jason" as second row (A3)
Name the sheet (for example "Sheet1"). If you change this, you will need to change the value also in your API request path= (see step 5 below)

In Google Sheet Top Menu, Click on Extensions -> App Script
Edit the Code.gs file and copy paste this repository Code.gs. Make sure to edit row 70 "Users" with the name of header of your column A -> rowData.push(e.parameter['Users'] || '');
Set a "project title" name and click on "Deploy" -> "New Deployment"

Set Permissions of Apps Script and Publish Make sure to deploy as "Web app" and copy the Web App URL: https://script.google.com/macros/s/xxxxxxxxxxxxxx/exec (make sure to replace the x's with your ID)
Using the Api and Testing Take the "Web App URL" and Use it in the Following Way: a. Read the Sheet

Add to the end of the "Web App URL" ?path=Sheet1&action=read b. Write to the Sheet (Add a new row)
Add to the end of the "Web App URL" ?path=Sheet1&action=write&Users=[name]

This script before writing to bottom of sheet, will check for duplicates. It you are trying to write a value that already exists in the sheet, it will decline the new entry and let you know.
Make make sure to read more about sharing access with Google Sheets, Google Sheets and Apps Scripts guidelines, quotas, limitations and costs before trying to setup your own versions.
