Messaging and Queuing SQS API

Introduction

The Simple Queue Service, or SQS, is a managed messaging service developed by AWS and supported by Scaleway Messaging and Queuing. If you're new to SQS, you can learn more about it on our SQS/SNS overview page.

Concepts

Refer to our dedicated concepts page to find definitions of all terminology related to Messaging and Queuing.

Quickstart

1. Configure your environment variables

   Note:

   This is an optional step that seeks to simplify your usage of the API.

   export SCW_SECRET_KEY="<API secret key>"
   export SCW_PROJECT_ID="<Scaleway Project ID>"Copy

2. Activate the SQS protocol on your Scaleway Project:

   curl --silent -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     "https://api.scaleway.com/mnq/v1beta1/regions/fr-par/activate-sqs" \
       -d '{
         "project_id": "'$SCW_PROJECT_ID'"
       }' | jq
   curl --silent -X GET \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     "https://api.scaleway.com/mnq/v1beta1/regions/fr-par/sqs-info?project_id=$SCW_PROJECT_ID" \
       | tee my-sqs-account.json | jqCopy

   Tip:

   • | tee my-sqs-account.json saves the JSON object returned by the API to a file (used by next steps)
   • | jq displays the output nicely

3. Create credentials. Credentials are necessary to authenticate a client to your SQS service. Their permissions should be specified and adapted according to your needs, using true or false for each type of permission.

   curl --silent -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     "https://api.scaleway.com/mnq/v1beta1/regions/fr-par/sqs-credentials" \
       -d '{
         "name": "my-credentials",
         "permissions": {
           "can_publish": true,
           "can_receive": true,
           "can_manage": true
         },
         "project_id": "'$SCW_PROJECT_ID'"
       }' | tee my-sqs-credentials.json | jqCopy

4. Export credentials: Export the credentials to your environment:

   export AWS_ENDPOINT_URL=$(jq -r .sqs_endpoint_url my-sqs-account.json)
   export AWS_ACCESS_KEY_ID=$(jq -r .access_key my-sqs-credentials.json)
   export AWS_SECRET_ACCESS_KEY=$(jq -r .secret_key my-sqs-credentials.json)Copy

5. Start creating queues and messages. The following commands show you how to create a queue, and send, receive and delete a message

   aws sqs create-queue --queue-name my-queue | tee my-queue.jsonCopy

   aws sqs send-message --queue-url "$(jq -r .QueueUrl my-queue.json)" \
     --message-body 'Hello world!'Copy

   aws sqs receive-message --queue-url "$(jq -r .QueueUrl my-queue.json)" \
     > my-sqs-message.jsonCopy

   aws sqs delete-message --queue-url "$(jq -r .QueueUrl my-queue.json)" \
     --receipt-handle "$(jq -r '.Messages[0].ReceiptHandle' my-sqs-message.json)"Copy

6. Disable SQS

   Important:

   Disabling SQS deletes all queues and messages stored in your SQS service.

   curl --silent -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
       "https://api.scaleway.com/mnq/v1beta1/regions/fr-par/deactivate-sqs" \
       -d '{
         "project_id": "'$SCW_PROJECT_ID'"
       }' | jqCopy

Technical limitations

Scaleway Messaging and Queuing does not support the entire set of AWS SQS actions or parameters. See the compatibility matrix for more information.

Also note that:

• The maximum message size is 256 kB.
• The maximum storage capacity for all queues of a project is 100 MB.

Technical information

Regional availability

Scaleway Messaging and Queuing is currently only available in the Paris, France region (fr-par).

SQS credentials

Credentials use a simplified permissions system with 3 permissions:

• can_publish : allows to send messages to a Queue.
• can_receive : allows to receive and acknowledge (delete) messages.
• can_manage : allows all other actions (Creating, Listing, Updating, Deleting Queues).

Each set of credentials gives access to all queues. Isolation can be handled by using several Scaleway Projects.
