NEW: Subscribe to email notifications for releases and breaking changes.

This library allows you to quickly and easily use the SendGrid Web API v3 via Ruby.

Version 3.X.X+ of this library provides full support for all SendGrid Web API v3 endpoints, including the new v3 /mail/send.

This library represents the beginning of a new path for SendGrid. We want this library to be community driven and SendGrid led. We need your help to realize this goal. To help make sure we are building the right things in the right order, we ask that you create issues and pull requests or simply upvote or comment on existing issues or pull requests.

Please browse the rest of this README for further detail.

We appreciate your continued support, thank you!

Installation

Prerequisites

• Ruby version >= 2.2
• The SendGrid service, starting at the free level

Setup Environment Variables

Update the development environment with your SENDGRID_API_KEY, for example:

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env

Install Package

Add this line to your application's Gemfile:

gem 'sendgrid-ruby'

And then execute:

bundle

Or install it yourself using:

gem install sendgrid-ruby

Dependencies

• Ruby-HTTP-Client
• Sinatra - this is only needed if you plan to process Inbound Email.

Quick Start

Hello Email

The following is the minimum needed code to send an email with the /mail/send Helper (here is a full example):

With Mail Helper Class

require 'sendgrid-ruby'
include SendGrid

from = Email.new(email: 'test@example.com')
to = Email.new(email: 'test@example.com')
subject = 'Sending with SendGrid is Fun'
content = Content.new(type: 'text/plain', value: 'and easy to do anywhere, even with Ruby')
mail = Mail.new(from, subject, to, content)

sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.mail._('send').post(request_body: mail.to_json)
puts response.status_code
puts response.body
puts response.headers

For more complex scenarios, please do not use the above constructor and instead build your own personalization object as demonstrated here.

Without Mail Helper Class

The following is the minimum needed code to send an email without the /mail/send Helper (here is a full example):

require 'sendgrid-ruby'
include SendGrid

data = JSON.parse('{
  "personalizations": [
    {
      "to": [
        {
          "email": "test@example.com"
        }
      ],
      "subject": "Sending with SendGrid is Fun"
    }
  ],
  "from": {
    "email": "test@example.com"
  },
  "content": [
    {
      "type": "text/plain",
      "value": "and easy to do anywhere, even with Ruby"
    }
  ]
}')
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.mail._("send").post(request_body: data)
puts response.status_code
puts response.body
puts response.headers

General v3 Web API Usage (With Fluent Interface)

require 'sendgrid-ruby'
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client.suppression.bounces.get()
puts response.status_code
puts response.body
puts response.headers

General v3 Web API Usage (Without Fluent Interface)

require 'sendgrid-ruby'
sg = SendGrid::API.new(api_key: ENV['SENDGRID_API_KEY'])
response = sg.client._("suppression/bounces").get()
puts response.status_code
puts response.body
puts response.headers
