User-specific settings also include settings for external services. Only the CDN address is required and necessary, the others are completely optional. The aim is to select external services that provide a real added value to the use of the publishing application and for which no payment is necessary. The image shows only a couple of external services for which an API is required, but there are a lot possible services to be used.

To avoid unnecessarily taking responsibility for external services that users may have paid for separately, apikeys are primarily stored to cookies in user's browser. If user wishes to save the apikeys to a database on the server, an alternative "Save apikeys to database" button is displayed, when pressing the Ctrl key. Apikeys are only stored in one of two places, either in the database or locally as cookies, i.e. when saving them to cookies they get removed from the database and vice versa.
