You can see the pixels connected by going to Assets > Pixels on the left-side bar.
Adphorus platform gets the pixel data from Facebook so the pixel is not firing the events to Adphorus specifically.
If you'd like to se if the SDK is connected, the app you connected with Adphorus has SDK implemented in itself, so it means its SDK is connected with Adphorus if you can see the app on the platform. There is not a specific section where you can see the connection. Likewise, the data of that information is taken from Facebook. You can see the connected apps you have by going to Assets > Connections.
