After completing the installation, you will need to complete two steps for any client applications.
Firstly, you will need to log in to Loome Identity and create a new client configuration.
Secondly, you will need to reconfigure your client application with the new Client ID and Secret from the above new client.
If you are running Loome Publish, this will require you to re-run the setup program and enter the new Client ID and Secret. The Loome Publish installation documentation contains steps for creating the Client on Loome Identity and running the setup program, where you will be prompted for the Client ID and Secret.
