Go

Send your first message from a Go project with the official Postwick library.

Add the Postwick Go SDK to this project, read POSTWICK_API_KEY from the environment and send a test email to delivered@postwick.dev.

Prerequisites

Before you begin you need:

• A Postwick API key

• A verified sending domain

Guide

1. Install

   Add the library to your project.

   go get github.com/postwick/postwick-go

2. Store your API key

   Keep the key out of source control by putting it in an environment variable.

   POSTWICK_API_KEY=pw_live_4f9c2e7a1b

3. Send an email

   The smallest useful call takes a sender, a recipient, a subject and a body.

   package main
   
   import (
   	"fmt"
   	"os"
   
   	"github.com/postwick/postwick-go"
   )
   
   func main() {
   	client := postwick.NewClient(os.Getenv("POSTWICK_API_KEY"))
   	sent, err := client.Emails.Send(&postwick.SendEmailRequest{
   		From:    "Lumen <hello@mail.lumen.dev>",
   		To:      []string{"ada@example.com"},
   		Subject: "Your receipt from Lumen",
   		Html:    "<p>Thanks for your order, Ada.</p>",
   	})
   	if err != nil {
   		panic(err)
   	}
   	fmt.Println(sent.Id)
   }
