We are installing a package that has an integration to an external system. The external system requires authentication with a connected app.
We don't want to tie the authentication/integration to a single user's login credentials in the event that the user's record is deactivated.
We want to use the "Salesforce Integration User" license that comes free with salesforce. However, we can't successfully login through the connected app because the user is API only and we get an error.
How can we use the Salesforce Integration User with an external connected app?
