SSRS REST API v2

Here is a response from the SSSR REST API in action.. (you can access a lot more SSRS item properties and customize at will once you know the API)


The SSRS API v2 has far more functionality than v1, but they essentially work the same. You must be authenticated to the SSRS report server you are targeting (localhost in this case) to make web GET/POST requests to the API.

Once auth'd you can push and pull any useful SSRS data pretty easily to make SSRS do some pretty cool things it can't do out of the box..


This is the SSRS API as accessed through a web browser; simply give your .NET app an HttpClient and you can make use of all these responses; it's just JSON...



You can get a collection of SSRS catalog items as in the example above (folders, reports, KPIs) by just specifying the action name, or you can select an individual item by putting the item GUID in parenthesis in the API request URL:


You can access individual items in the API via GUID in parens after the API action name.




Common Useful SSRS API v2 Actions:
  • Reports
  • Datasets
  • Data Sources
  • Folders
  • Schedules
  • Subscriptions
  • Comments
  • KPIs
  • CatalogItems (everything)



Example of a .NET Standard library with an HttpService abstacting the SSRS API calls:
 namespace ExtRS  
 {  
   public class SSRSHttpService  
   {  
     const string ssrsApiURI = "https://localhost/reports/api/v2.0";  
     HttpClient client = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true });  
         public async Task<GenericItem> GetReportAsync(Guid id)  
     {  
       client.BaseAddress = new Uri(ssrsApiURI + string.Format("/reports({0})", id));  
       var response = await client.GetAsync(client.BaseAddress);  
       var odata = response.Content.ReadAsStringAsync().Result;  
       return JsonConvert.DeserializeObject<GenericItem>(odata);  
     }  
   }  
 }  
This is verbose to better break down the steps of what is happening on the ExtRS service end




A very basic class designed to demonstrate using SSRS API Response to create a .NET object:
 using Newtonsoft.Json;  
 using System.Collections.Generic;  
 namespace ExtRS  
 {  
   public class GenericItem  
   {  
     [JsonProperty("@odata.context")]  
     public string ODataContext { get; set; }  
     [JsonProperty("Id")]  
     public string Id { get; set; }  
     [JsonProperty("Name")]  
     public string Name { get; set; }  
     [JsonProperty("Path")]  
     public string Path { get; set; }  
   }  
 }  
The power of the SSRS API is limited primarily your imagination- lots of customization can be made




And finally, called from a Controller Action in an MVC app:
 using System;  
 using System.Web.Mvc;  
 using System.Threading.Tasks;  
 using ExtRS;  
 namespace Daylite.Controllers  
 {  
   public class ReportsController : Controller  
   {  
     public SSRSHttpService service = new SSRSHttpService();  
     public async Task<ViewResult> GetReportsAsync()  
     {  
       return View("Index", await service.GetReportsAsync());  
     }  
     public async Task<ViewResult> GetFoldersAsync()  
     {  
       APIGenericItemsResponse result = await service.GetFoldersAsync();  
       return View("Index", result);  
     }  
     public async Task<ViewResult> GetReportAsync(Guid id)  
     {  
       GenericItem result = await service.GetReportAsync(id);  
       return View("Index", result);  
     }  
   }  
 }
