Working with Amazon SQS APIs - Amazon Simple Queue Service

Working with Amazon SQS APIs

This section provides information about constructing Amazon SQS endpoints, making query API requests using the GET and POST methods, and using batch API actions. For detailed information about Amazon SQS actions—including parameters, errors, examples, and data types, see the Amazon Simple Queue Service API Reference.

To access Amazon SQS using a variety of programming languages, you can also use AWS SDKs, which contain the following automatic functionality:

  • Cryptographically signing your service requests

  • Retrying requests

  • Handling error responses

For command line tool information, see the Amazon SQS sections in the AWS CLI Command Reference and the AWS Tools for PowerShell Cmdlet Reference.

Amazon SQS APIs with AWS JSON protocol

Amazon SQS uses AWS JSON protocol as the transport mechanism for all Amazon SQS APIs on the specified AWS SDK versions. AWS JSON protocol provides a higher throughput, lower latency, and faster application-to-application communication. AWS JSON protocol is more efficient in serialization/deserialization of requests and responses when compared to AWS query protocol. If you still prefer to use the AWS query protocol with SQS APIs, see What languages are supported for AWS JSON protocol used in Amazon SQS APIs? for the AWS SDK versions that support Amazon SQS AWS query protocol.

Amazon SQS uses AWS JSON protocol to communicate between AWS SDK clients (for example, Java, Python, Golang, JavaScript) and the Amazon SQS server. An HTTP request of an Amazon SQS API operation accepts JSON formatted input. The Amazon SQS operation is executed, and the execution response is sent back to the SDK client in JSON format. Compared to AWS query, AWS JSON is simpler, faster, and more efficient to transport data between client and server.

  • AWS JSON protocol acts as a mediator between the Amazon SQS client and server.

  • The server doesn’t understand the programming language in which the Amazon SQS operation is created, but it understands the AWS JSON protocol.

  • The AWS JSON protocol uses the serialization (convert object to JSON format) and de-serialization (convert JSON format to object) between Amazon SQS client and server.

For more information about AWS JSON protocol with Amazon SQS, see Amazon SQS AWS JSON protocol FAQs.

AWS JSON protocol is available on the specified AWS SDK version. To review SDK version and release dates across language variants, see the AWS SDKs and Tools version support matrix in the AWS SDKs and Tools Reference Guide
