Hi, I've done that before using the logic app http connector
https://learn.microsoft.com/en-us/azure/connectors/connectors-native-http
unfortunately look like Logic apps have a limited amount of Amazon connectors and lambda is not one of them
you need to consume it like an API. The http connector is similar to postman :https://docs.aws.amazon.com/apigateway/latest/developerguide/call-api-with-api-gateway-lambda-authorization.html
I haven't tried this approach but here is a detailed blog post:
