I've been looking for a solution to my problem for a long time:
I am currently programming an Alexa Skill with the Alexa Smart Home API (https://developer.amazon.com/en-US/docs/alexa/smarthome/steps-to-build-a-smart-home-skill.html) so far everything is running and I can "create" devices, the ultimate goal is to communicate via an HTTP server running on a Raspberry Pi, which should then do things. The part also runs without problems, if I enter the appropriate URL, then the desired output comes up. What I am missing is how I can call a URL in the Lambda function.
I'm looking forward to quick help and hope I've hit the right topic.
