Event Source for AWS SQS

The event source captures messages sent to a [AWS SQS queue][sqs-docs] and sends them as CloudEvents to an event sink.


SQS Queue

If you don't already have an AWS SQS queue, create one by following the instructions in the Getting started with Amazon SQS guide.

Amazon Resource Name (ARN)

A fully qualified ARN is required to uniquely identify the AWS SQS queue.

SQS queue

As shown in the above screenshot, you can obtain the ARN of a SQS queue from the AWS console. It typically has the following format:


Alternatively you can also use the AWS CLI. The following command retrieves the ARN of a SQS queue named MyQueue in the us-west-2 region.

$ aws --region us-west-2 sqs get-queue-attributes --queue-url $(aws --region us-west-2 sqs list-queues --queue-name MyQueue | jq -r .QueueUrls[0]) --attribute-names QueueArn
    "Attributes": {
        "QueueArn": "arn:aws:sqs:us-west-2:123456789012:MyQueue"

API Credentials

The TriggerMesh AWS SQS event source authenticates calls to the AWS SQS API using an Access Key. The page at this link contains instructions to create an access key when signed either as the root user or as an IAM user. Take note of the Access Key ID and Secret Access Key, they will be used to create an instance of the event source.

It is considered a good practice to create dedicated users with restricted privileges in order to programmatically access AWS services. Permissions can be added or revoked granularly for a given IAM user by attaching IAM Policies to it.

As an example, the following policy contains the permissions required by the TriggerMesh AWS SQS event source to read and delete messages from any queue linked to the AWS account:

    "Version": "2012-10-17",
    "Statement": [
            "Sid": "AWSSQSSourceReceiveAdapter",
            "Effect": "Allow",
            "Action": [
            "Resource": [

Creating an IAM user

Deploying an Instance of the Source

Open the Bridge creation screen and add a source of type AWS SQS.

Adding an AWS SQS source

In the Source creation form, give a name to the event source and add the following information:

  • Secret: Reference to a TriggerMesh secret containing an Access Key ID and a Secret Access Key to communicate with the AWS SQS API, as described in the previous sections.
  • AWS ARN: ARN of the SQS queue, as described in the previous sections.

AWS SQS source form

After clicking the Save button, you will be taken back to the Bridge editor. Proceed to adding the remaining components to the Bridge, then submit it.

Bridge overview
