Introduction

In order for Gravity SMTP to send messages from your Google / Gmail account, you will need to create an application in Google Cloud Console and provide the plugin with a token. You must complete this step before configuring the Google/Gmail integration in Gravity SMTP. This article outlines the steps to create a web app in the Google Cloud Console.

Prerequisites

• A Google account with access to Google Cloud Console. A billing account is not required to enable the Gmail API or send mail at normal volumes.

Step 1: Create a Project

1. Visit Google Cloud Console
   Open your browser and go to Google Cloud Console.
2. Create or Select a Project
   Click on the project dropdown menu in the top navigation bar. You can create a new project or select an existing one.

3. Switch to the Preferred Project
   Once the project is created or selected, ensure it’s active by selecting it from the dropdown menu.

Step 2: Enable the Gmail API

1. Navigate to APIs & Services
   In the Google Cloud Console, go to the “APIs & Services” section and click on “Library.”

2. Search for Gmail API
   Type “Gmail API” in the search bar and select it from the search results.

3. Enable the API
   Click the “Enable” button to activate the Gmail API for your project.

Step 3: OAuth2 – App Registration

Note: This step is only required to register a new app. If you have already created an app, you can skip to Step 4 to create a Client for the app.

1. Go to Google Auth Platform
   In the Cloud Console, open the left-hand menu and select “Google Auth Platform.” On a new project, you will see “Google Auth platform not configured yet.” Click “Get Started”.

2. App Information
   Enter your app name and a user support email.

3. Audience
   Select “External” and click “Next.”

4. Contact Information
   Enter the developer’s contact email.

5. Finish
   Review and accept the Google API Services User Data Policy, then click “Continue” and “Create.”

Step 4: Set Up OAuth2 Credentials

1. Navigate to Clients
   Within Google Auth Platform, click the “Clients” tab in the left-hand menu.
2. Create Client
   Click “Create Client.”

3. Choose Application Type
   Select “Web application” as the application type.
4. Enter Client Details
   Provide a name for your OAuth client and add an Authorized Redirect URI. You will use the one provided by Gravity SMTP in the Google / Gmail connection settings.

5. Create the Client
   Click “Create” to generate your OAuth credentials.

Step 5: Publish your App

1. Go to Audience. Click on Publish App.

2. Confirm publishing
   Click “Push to Production” in the dialog that appears.

Note: Until your app passes Google’s formal verification process, users authorizing it, including you, will see an “unverified app” screen.
