AWS API-Gateway communicating to SNS

Question

I am building an API which will be serviced by Lambda functions but I need these to be asynchronous so rather than connecting the API-Gateway directly to the Lambda function

Answer 1

I'm from the Api Gateway team.

I believe there are a few formats for the HTTP request to the Publish API, but here's the one I used first:

AWS Region us-west-2

AWS Service sns

AWS Subdomain

HTTP method POST

Action Publish

== query strings ==

Subject 'foo'
Message 'bar'
TopicArn 'arn:aws:sns:us-west-2:xxxxxxxxxxxx:test-api'

This worked for me to publish a message.

Let me know if you have further troubles.
