Questions about API Definitions for RainMaker Backend Service

[Bernawong4]

Hi guys,

I am currently working on a ESP RainMaker project, and just finished the ESP32 firmware. Right Now, I have tried to design a customised Web-based control panel to control my devices using Swagger UI. However, I have faced some problems.

1. Can I use Swagger UI on free version of ESP RainMaker?
2. If yes, is there any configuration that need to be modified in ESP IDF?
3. How can I get the API key?

Please feel free to ask me for any further required information.
