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!

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.envgo get github.com/sendgrid/sendgrid-go
import "github.com/sendgrid/sendgrid-go"The following is the minimum needed code to send an email with the /mail/send Helper (here is a full example):
package main
import (
"fmt"
"github.com/sendgrid/sendgrid-go"
"github.com/sendgrid/sendgrid-go/helpers/mail"
"os"
)
func main() {
from := mail.NewEmail("Example User", "test@example.com")
subject := "Hello World from the SendGrid Go Library"
to := mail.NewEmail("Example User", "test@example.com")
content := mail.NewContent("text/plain", "some text here")
m := mail.NewV3MailInit(from, subject, to, content)
request := sendgrid.GetRequest(os.Getenv("SENDGRID_API_KEY"), "/v3/mail/send", "https://api.sendgrid.com")
request.Method = "POST"
request.Body = mail.GetRequestBody(m)
response, err := sendgrid.API(request)
if err != nil {
fmt.Println(err)
} else {
fmt.Println(response.StatusCode)
fmt.Println(response.Body)
fmt.Println(response.Headers)
}
}The NewV3MailInit constructor creates a personalization object for you. Here is an example of how to add to it.
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"
"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": "Hello World from the SendGrid Go Library!"
}
],
"from": {
"email": "test@example.com"
},
"content": [
{
"type": "text/plain",
"value": "Hello, Email!"
}
]
}`)
response, err := sendgrid.API(request)
if err != nil {
fmt.Println(err)
} else {
fmt.Println(response.StatusCode)
fmt.Println(response.Body)
fmt.Println(response.Headers)
}
}package main
import (
"fmt"
"github.com/sendgrid/sendgrid-go"
"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 {
fmt.Println(err)
} else {
fmt.Println(response.StatusCode)
fmt.Println(response.Body)
fmt.Println(response.Headers)
}
