Trigger a Step Function from SNS

Question

I want to execute my step function when an SNS message is published and consume it. What's the best solution for this?

I know that one option is using a Lambda, subscribe to the SNS topic, and then trigger the SF from inside the Lambda....I was wondering if there's any (simpler) solution without this intermediate step.

Answer 1

Unfortunately not SNS. You can invoke a StepFunction from:

• Lambda
• API Gateway
• EventBridge
• CodePipeline
• IoT Rules Engine
• (other) Step Functions
