Description
A geoprocessing task resource represents a single task in a geoprocessing service published to ArcGIS Server. It provides the task name, display name, and detailed information about various input and output parameters.
A geoprocessing task resource supports the following operations:
submit—For tasks with an asynchronous operation type. An asynchronous type means that the application does not wait for the task to complete, and the end user can continue using the application. A client must actively check the status of the job to learn its progress and results when finished.Job execute—For tasks with a synchronous operation type. A synchronous type means that the application waits while the tool runs on the server. Because the end user must wait, determine whether the wait time is acceptable for the type of application. Fast running analysis is a common use case for synchronous type. However, an output feature service is not available.
Child resources
At 10.9.1, the new metadata child resource is available. It shows the metadata for a geoprocessing task resource in XML format only. No request parameter is needed. An example usage is to access the metadata using the following URL:
Getting the metadata for the My task.
https://machine.domain.com/webadaptor/rest/services/myServiceName/GPServer/MyTaskName/metadata.

Example usage
Example 1: Request URL for the Create task for ESRI.
This request will return the HTML page of the GPTask.
https://machine.domain.com/webadaptor/rest/services/Network/ESRI_DriveTime_US/GPServer/CreateDriveTimePolygonsExample 2: Request URL for the 911 call hot spot analysis with a JSON return format:
This request will return the GPTask with JSON.
https://machine.domain.com/webadaptor/rest/services/911CallsHotspot/GPServer/911%20Calls%20Hotspot?f=jsonJSON Response schema
The JSON schema shown below is for a geoprocessing task response when queried with JSON. The filter property is available starting at ArcGIS Server 10.7. The parameter property is available starting at ArcGIS Server 11.0. The GPValueTable, GPMultiValue, and GPComposite data types are subject to the availability of that data type in your ArcGIS Server version.
