What is the authentication of Location Services with API Key?

Jan Tschada

The easiest way to get direct access to the Location Services of ArcGIS Platform is to use an API Key. When creating a Qt Creator project with the ArcGIS Maps SDKs for Qt  template, a placeholder for the corresponding API Key is generated in the source code. You just need to go to your own Developer Dashboard, create a corresponding API Key, and then you can manage access to the Location Services. The API Key is simply replaced in the source code or read via a configuration mechanism - e.g., via a corresponding environment variable.<\/P>
