Once you have TransistorWP installed and activated you should see a new menu item, TransistorWP, within your WordPress admin dashboard. There are two pages of settings, one for your license and one for settings pertaining to how TransistorWP works. Within the TransistorWP settings page you'll see the following settings:
Transistor API Key
This is your API key from your account it can be found at the bottom of your account page. Without this API key set we are not able to connect to and get the details needed for TransistorWP to work.
Default Show
Since TransistorWP supports accounts with more than one show you can select a default show here to preselect a specific show when inserting TransistorWP blocks.
