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 workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Publish SNS Message support batch operations?
Yes. Run Publish SNS Message inside a Loop node to process arrays. TinyCommand handles AWS SNS's rate limits automatically so you don't have to throttle manually.
