Describe the issue/error/question

Hi, I am trying to use the AWS SNS Trigger but I could not find a list of permissions/scopes it need to work with AWS. I want to keep the IAM policy as limited as I can.

Can someone point me to any docs or code where I can look for this information?

TLDR: IAM policy requirements for AWS SNS Trigger.

What is the error message (if any)?

Hey @faheem,

Welcome to the community :raised_hands:

I am not sure how AWS scopes work but you can find the code for the node here: n8n/AwsSnsTrigger.node.ts at master · n8n-io/n8n · GitHub

Thanks, Jon. My use-case was very simple and I decided to go with a simple Lambda function instead.

But for anyone with the same question, the node only needs access to these actions.

Here is the AWS doc for these actions.
