This library allows you to quickly and easily use the Twilio SendGrid Web API v3 via Go.
Version 3.X.X of this library provides full support for all Twilio SendGrid Web API v3 endpoints, including the new v3 /mail/send.
This library represents the beginning of a new path for Twilio SendGrid. We want this library to be community driven and Twilio 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.
If you need help using SendGrid, please check the Twilio SendGrid Support Help Center.
This library supports the following Go implementations:
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
go get github.com/sendgrid/sendgrid-go
cp .env_sample .env
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
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"
"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 Twilio 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.
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 Twilio 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)
}
}
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)
}
}
