I just created a sandbox app for testing and development purposes. and I’m trying to connect my staging website to it. To do so, I need values for ClientID and ClientSecret. I’ve looked around the app dashboard and settings screens, and don’t see anything that looks like a way to view or generate these values. Is this one of the things sandbox apps can’t do? If I can generate these values for a sandbox app, how do I do it?
You need to create a Developer Account here: https://keys.developer.keap.com/
After you have logged into the account, you can create an App which will generate the Client ID and Secret for you.
