This page lets review the connection settings to the Origami API installed on your server. If you move your API to a different domain or change the Origami API Token in the .env file, you can adjust the values here to restore the communication between Origami App Builder and your server.
Keep in mind that the Origami App Builder platform is only used for setting up your app. When you click publish, the settings are transferred to your server and stored in your database. When the mobile app starts, it loads the settings from your own server and never from ours.
