Consume HA APIs in third party flutter app

Hi All,

I’m completely new to Home Assistant and looking for some assistance. I have already installed the Home Assistant OS in my Raspberry PI and I need to create a flutter app that will consume the Home Assistant APIs to onboard and control the IoT devices. is it possible to consume their API from the other third-party flutter app? how to do that?

Thanks for replying to this. There is a minimal amount of API in the HA document. REST and also the WebSocket. The commissioning API and Device integration APIs are not available. I know, They’re using the Google play services for commissioning, but after the commission is successful, how does HA onboard these devices?
