Build Status

Please see our announcement regarding breaking changes. Your support is appreciated!

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

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

  • Go version 1.6
  • 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

go get github.com/sendgrid/sendgrid-go

Dependencies

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
package main

import (
	"fmt"
	"log"
	"os"

	"github.com/sendgrid/sendgrid-go"
	"github.com/sendgrid/sendgrid-go/helpers/mail"
)

func main() {
	from := mail.NewEmail("Example User", "test@example.com")
	subject := "Sending with SendGrid is Fun"
	to := mail.NewEmail("Example User", "test@example.com")
	plainTextContent := "and easy to do anywhere, even with Go"
	htmlContent := "<strong>and easy to do anywhere, even with Go</strong>"
	message := mail.NewSingleEmail(from, subject, to, plainTextContent, htmlContent)
	client := sendgrid.NewSendClient(os.Getenv("SENDGRID_API_KEY"))
	response, err := client.Send(message)
	if err != nil {
		log.Println(err)
	} else {
		fmt.Println(response.StatusCode)
		fmt.Println(response.Body)
		fmt.Println(response.Headers)
	}
}

The NewEmail constructor creates a personalization object for you. Here is an example of how to add to it.

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):

package main

import (
	"fmt"
	"github.com/sendgrid/sendgrid-go"
	"log"
	"os"
)

func main() {
	request := sendgrid.GetRequest(os.Getenv("SENDGRID_API_KEY"), "/v3/mail/send", "https://api.sendgrid.com")
	request.Method = "POST"
	request.Body = []byte(` {
	"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 Go"
		}
	]
}`)
	response, err := sendgrid.API(request)
	if err != nil {
		log.Println(err)
	} else {
		fmt.Println(response.StatusCode)
		fmt.Println(response.Body)
		fmt.Println(response.Headers)
	}
}

General v3 Web API Usage

package main

import (
	"fmt"
	"github.com/sendgrid/sendgrid-go"
	"log"
	"os"
)

func main() {
	request := sendgrid.GetRequest(os.Getenv("SENDGRID_API_KEY"), "/v3/api_keys", "https://api.sendgrid.com")
	request.Method = "GET"

	response, err := sendgrid.API(request)
	if err != nil {
		log.Println(err)
	} else {
		fmt.Println(response.StatusCode)
		fmt.Println(response.Body)
		fmt.Println(response.Headers)
	}
}
