Setting Oauth cliens

A number of integrations (such as Zapier, Microsoft Flow/Powerautomat) require an Oauth connection.

For these connections a client id and secret must be entered once.

In your admin panel, go to Configuration > System > Oauth clients

Client ID is unique per environment. If multiple licenses are included in one environment, the message may be displayed:
"Client ID already exists. Please choose a different Client ID."
Without this Client ID being visible. In this case, this Client ID has been taken into use by another license.
Then use a different Client ID.
