Setting the API key in Site Configuration
Authentication using the RESTful API requires an API key, as explained in the API authentication topic. The API key is set in the FotoWeb Site Configuration.
From the Tools menu (cogwheel icon), go to Site Configuration > Integrations > Legacy Integrations.
Important: If you build an integration based on the API key and then change it in the Site Configuration, the integration will no longer work until you update the key accordingly in your integration.
