How to Send Email using Gmail API in PHP
In this tutorial, we build a script that sends emails using Gmail API in PHP. It requires you to follow OAuth 2.0 and grab the access token. Then with the combination of Google email and access token email can be sent.
Register Google Application and Create Credentials.
1) Go to the https://console.developers.google.com
2) Create a new project. You can also select an existing project.
3) Add a name to your project. Google Console will generate a unique Project ID for it.
4) Your project will appear on top of the left sidebar.
5) Click on Library. You will see a list of Google APIs.
6) Enable Gmail API.
7) Click on the Credentials. Select Oauth Client id under Create credentials. Choose the radio button for Web Application.
8) Give the Name. In the ‘Authorized redirect URIs’ add the link of the redirect URL. In my case, I passed the URL http://localhost/mailer/callback.php
9) Click on the Create button. You will get a client ID and client secret in the pop-up. Copy these details. We will need it in a moment.
