This API consumes ArcGIS Server services using the REST API. The ArcGIS Server REST infrastructure provides the ArcGIS Services Directory application to discover information about the services available on an ArcGIS Server site.
Use the ArcGIS Services Directory to search for available services (including secured services with proper login) and view service details such as:
- REST URL to consume the service
- Tile levels for cached map services
- Extent and supported operations
- Layer information
- Required input for locator services
- Input and output types for tools in a geoprocessing service
Open the ArcGIS Services Directory
To open the ArcGIS Services Directory for an ArcGIS Server site, you must know the URL of the server instance. The ArcGIS Server instance is typically available off the web server's root in the arcgis directory. The ArcGIS Services Directory is in the rest/services folder inside the instance. For example, if an ArcGIS Server instance is available at www.example.com, the ArcGIS Services Directory would be located at http://www.example.com/arcgis/rest/services.
Contact your ArcGIS Server system administrator if you are uncertain about the server's URL, or ArcGIS instance.
Find information about a service
You can use the ArcGIS Services Directory to obtain information about any service you need to incorporate into your application. In most cases, copy a service's URL from the address bar in your browser and paste it in your code. For example, a map service named California and hosted on the server serverapps.esri.com may have a URL of http://serverapps.esri.com/arcgis/rest/services/California/MapServer.
For all ArcGIS Server services, the server type is appended to the end of the URL and is required to specify the type of service used.
The services directory also allows you to search for layer IDs you can use to identify and query features within particular layers. The layer IDs can be found in the layers list on a map service's properties page. Each layer also contains a list of attribute field names, which can be used to create a query and define return fields in a query result.
Some services may be secured so that only authorized users may access them. Log in to the ArcGIS Services Directory to see which services you have access to.
