Event Webhook Go Code Example
We recommend using our official Go SDK, our client library with full documentation, when integrating with SendGrid's Inbound Parse Webhook.
In this example, we want to parse all emails at address@email.sendgrid.biz and post the parsed email to http://sendgrid.biz/upload
Given this scenario, the following are the parameters you would set at the Parse API settings page:
Hostname: email.sendgrid.biz
URL: http://sendgrid.biz/upload
To test this scenario, we sent an email to example@example.com and created the following code:
package main
import (
"fmt"
"net/http"
"io/ioutil"
"log"
"github.com/sendgrid/sendgrid-go"
)
func Parse (w http.ResponseWriter, req *http.Request) {
//Get Email Values
to := req.FormValue("from")
subject := req.FormValue("subject")
body:= req.FormValue("text")
//Get Uploaded File
file, handler, err := req.FormFile("attachment1")
if err != nil {
fmt.Println(err)
}
data, err := ioutil.ReadAll(file)
if err != nil {
fmt.Println(err)
}
err = ioutil.WriteFile(handler.Filename, data, 0777)
if err != nil {
fmt.Println(err)
}
}
func main() {
http.HandleFunc("/upload", Parse)
err := http.ListenAndServe(":3000", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
