How do I publish a message to an SNS topic?

Short answer: You can publish sns message in AWS SNS by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the AWS SNS Publish SNS Message action to a workflow, map its 3 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Publish SNS Message.

What does the Publish SNS Message action do in AWS SNS?

Pushes a message into an SNS topic with optional message attributes. SNS fans out to every subscriber (HTTP endpoints, Lambdas, SQS queues, email, SMS) — clean decoupling pattern when one event needs to reach N downstream consumers.

What inputs does Publish SNS Message require?

Required: Topic ARN, Message. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if AWS SNS returns an error?

The run history shows the failed step with its input and the error message AWS SNS returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Publish SNS Message support batch operations?

Run Publish SNS Message inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within AWS SNS's rate limits.
