Guide to Sending Messages to Amazon SQS Using Go


What is Amazon SQS?

Amazon Simple Queue Service (SQS) is a highly scalable and fully managed message queuing service provided by AWS. It facilitates the decoupling of distributed system components, ensuring message integrity and streamlined processing.

SQS is ideal for building scalable, distributed applications requiring reliable message delivery. It helps to handle asynchronous processing, ensures decoupling of microservices, and manages varying load levels efficiently.

Use Cases:

  • Asynchronous Task Execution: Handling background tasks like sending notifications or processing data without impacting user experience.
  • System Decoupling: Allowing components of a distributed system to communicate independently, improving system resilience and scalability.
  • Workload Management: Balancing and managing workloads efficiently across different components or services.

Step-by-Step Guide to Sending Messages to SQS with Go


  • Go environment setup.
  • AWS SDK for Go (aws-sdk-go) installed (go get
  • AWS account with access to SQS.
  • Configured AWS credentials, typically through the AWS CLI or environment variables.
  • An existing SQS queue.

Sending Messages to an SQS Queue in Go

Step 1: Import AWS SDK and Configure SQS Client

Start by importing the AWS SDK and setting up the SQS client:

package main

import (

func main() {
    sess := session.Must(session.NewSessionWithOptions(session.Options{
        SharedConfigState: session.SharedConfigEnable,
    sqsClient := sqs.New(sess)
    // ... remaining steps

Step 2: Define Your Queue URL

Specify the URL of your SQS queue:

queueUrl := "YourQueueUrl"

Replace "YourQueueUrl" with the actual URL of your queue.

Step 3: Create a Function to Send Messages

Define a function to send messages to your SQS queue:

func sendMessage(svc *sqs.SQS, queueUrl string, messageBody string) {
    sendMessageInput := &sqs.SendMessageInput{
        QueueUrl:    aws.String(queueUrl),
        MessageBody: aws.String(messageBody),

    result, err := svc.SendMessage(sendMessageInput)
    if err != nil {
        fmt.Println("Error", err)

    fmt.Printf("Message ID: %s\n", *result.MessageId)

Step 4: Send a Message

Use the function to send a message to the SQS queue:

func main() {
    // ... (previous setup code)
    sendMessage(sqsClient, queueUrl, "Hello, SQS!")

Replace "Hello, SQS!" with the content of the message you wish to send.


Sending messages to Amazon SQS using Go is a straightforward way to integrate reliable message queuing into your applications. This guide covers the essential steps for integrating SQS message sending into your Go applications, taking advantage of AWS's robust and scalable infrastructure.
