Apps-Script-Gmail-Push-Notifications-v2

An updated version of Gmail Push Notifications in Apps Script

This sample project shows how to setup your Apps Script project to register a Gmail account for push notifications and how to programmatically set up the the proper pubsub publishing channels and subscriptions.

Setup

1. Create a new Apps Script project using the two .gs files in this repo.
2. Add the following libraries:
       PubSubApp - 1BX8k4tkiA3CZGIZ0hHccfiF7o-EvjqLCt3hoU3osDQBhnGlQTRnawOGE
       GSApp - 1wkfv_Mm0IyruEZyPZsrctcSmc1T9y0-bArl2gIzMd6RVYJAwWeJ5gpDu
3. Publish the project as a web app
4. Register the web app in the Chrome web store leaving it in draft mode. This will verifiy ownership of the script.
5. Run the script from the cuurrent web app URL. (the /exec one). You will get an error about no doGet(). Copy the URL it redirected you toward.
6. Add the URL to the WEBHOOK_URL var in main.gs
7. Open up the project developers console:
       a) Under Credentials -> Domain Verification: Add the url you copied in WEBHOOK_URL in step 6 ommiting the exec from the end
       b) Create a new service account. Download the credentials as json.
       c) Under Overview: Enable the PubSub API and the Gmail API
       d) Copy the json credentials and paste it into script properties under the key jsonKey.
8. Copy the developers console project Id to PROJECTID var in main.gs
9. Create a spreadsheet. Create a sheet called Log. Copy the file Id and paste it in SpreadsheetApp.openById() of doPost().
10. Update the webapp version to pick up changes made to the project.

Running the sample code

1. Run setupPubSub()
2. Run enrollEmail() to start listening to your Gmail notifications. They will be logged to the spreadsheet set up in step 9.
3. Run disEnrollEmail() to stop listening to your Gmail notifications.
