v3 API Ruby Code Example

We recommend using SendGrid Ruby, our client library, available on GitHub, with full documentation.

Do you have an API Key yet? If not, go get one. You're going to need it to integrate!

# using SendGrid's Ruby Library

require 'sendgrid-ruby'
include SendGrid

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