Insights Hub CORS error calling backend API from frontend app

When calling a backend API from a frontend application, a CORS error is common if the frontend app and the backend API are hosted on different domains or origins. Browsers implement this policy for security purposes, disallowing such cross-origin requests unless the server permits them.

To resolve this, you can use the following URL structure for your API calls, which should bypass the CORS issue if configured correctly:

https://{userTenant}-{AppName}-{HostTenant}.eu1.mindsphere.io/api/{API_AppName}/v1/{Endpoints}

This URL pattern includes:

• userTenant: The tenant making the API request.
• AppName: The name of the application making the request.
• HostTenant: The host tenant of the backend API.
• API_AppName: The specific API application name.
• Endpoints: The desired API endpoints you are trying to access.
