A Partner App is any branded external app or service embedded as an App within your portal that is not provided and maintained by our platform.
For example, if you were to connect an Airtable View as an App, this would be considered a Partner App.
We have some articles on how to set up Partner Apps here: Partner App Setup
The Partner Apps listed in the article linked above are some of the most commonly used, but you can connect any app or service as a Partner App as long as it supports iframe embeds.
