# Post SQS Message

| ## Step Details |
| --- |
| **Introduced in Version** | 4.0.0 |
| **Last Modified in Version** | 8.9.0 |
| **Location** | Integration > Amazon AWS > SQS |

The **Post SQS Message** step accepts a String input as a message and returns an ID when the step completes. This ID will match the ID that the SQS queue generates.

The queue can also be specified for the step, which is done by expanding the Settings header in the Properties panel and selecting the queue for the QueueName in the drop-down menu or by checking Get Queue from Flow if used in a Message Queue Handler.

### Prerequisites

- This step requires the [Amazon AWS Module](https://documentation.decisions.com/docs/aws) to be [installed](https://documentation.decisions.com/docs/installing-modules-decisions) before it will be available in the toolbox, and an active [AWS account](https://signin.aws.amazon.com/signin?redirect_uri=https%3A%2F%2Fconsole.aws.amazon.com%2Fconsole%2Fhome%3FhashArgs%3D%2523%26isauthcode%3Dtrue%26nc2%3Dh_ct%26src%3Dheader-signin%26state%3DhashArgsFromTB_eu-north-1_c1412528899e4833&client_id=arn%3Aaws%3Asignin%3A%3A%3Aconsole%2Fcanvas&forceMobileApp=0&code_challenge=HQku5BPrRUboP5p1wGr4Ai_nBIQNSqsR2eHJNCBfxhQ&code_challenge_method=SHA-256). The [Amazon WebServices Settings](https://documentation.decisions.com/docs/setting-up-amazon-webservices-integration) must also be configured.
- A [dependency](https://documentation.decisions.com/docs/project-dependencies) must be created after installing the module in order for the the steps to be properly used.

## Common Errors

### Invalid URI

If the inputted value for the queue name under the Settings section is invalid, the step will cause an error.

To correct this, the parameters around the Message Queue are invalid and need to be reconfigured.
