2. Get an API key

API keys are required to access ArcGIS services, such as basemaps, geocoding, and routing. Visit your dashboard and copy your default API key, or set custom scopes and referrers for your specific needs. Include your API key in the tutorials and samples when required in the instructions. You can use a global API key, as well as more fine-grained API keys on specific classes.
