Executing Reports with the API


This version of the .NET API documentation is deprecated. A new version can be found at https://www.exagoaccess.com/api-docs/.

There are two different ways to use the Exago APIs to perform report execution. This guide discusses the main differences and provides examples for both types in each API.

  • API Action is the most comprehensive way to run executions, and supports all types of reports. This is the only way to run composite reports such as Dashboards and Chained Reports. This method launches an Exago session into the browser via URL, and thus usually requires the use of an Iframe. This also means that all interactive Report Viewer or ExpressView (v2016.3+) features are supported.
  • GetExecute() executes reports on the back-end and returns bare HTML, JSON, CSV, or binary data. GetExecute supports non-composite (Advanced, Express and CrossTab) reports and ExpressView (as of v20191.31+, 2019.2.19+ and v2020.1.5+). Using this method you do not have to launch any visible instance of Exago for the user, and can simply use it as a calculation engine.



    GetExecute methods are not supported by Remote Execution in versions pre-v2019.1.15. In v2019.1.15+, all calls of the GetExecute() functions will use the Remote Execution servers if configured.

    To disable this behavior, disable remote executions for the session with the API.

API Action

API sessions in Exago have a property called action type, which determines what part of Exago should be launched when the session is opened. Action types include executing a report, loading a report into the editor, loading a report into the scheduler, opening a section of the UI, etc.


API Action is also referred to as GetUrlParamString, because this is the general term for the methods which return the session redirect URL.

To tell the session to execute a report, set the action type to ExecuteReport.

Actions which load reports, such as Execute or Edit, work on the active report object. This is another property that must be set. This is done differently for each API: details are in the included examples.


For security reasons, always set the action type and the active report explicitly. Although setting an active report defaults to execute, if a report fails to load and an action has not been specified, Exago will launch into the full Web Application user interface. This could cause users to have unintended levels of access.

Once you’ve finished setting the session variables, call GetUrlParamString(). This finalizes the session and creates a single-use URL string. This is done differently for each API; details are in the included examples. The URL is used to direct a browser window or iFrame to an Exago instance where the specified action takes place. The user can then interact with the report like normal.

See the following sections for examples. Variable names and arguments are placeholders.


  1. //Create an API object and load a report object into it
    Api myApi = new Api(appPath);
    Report myReport = (Report)myApi.ReportObjectFactory.LoadFromRepository(reportPath);
  2. //Set the desired output type.
    myReport.ExportType = wrExportType.Html;
  3. //Save the modified report back to the API object
  4. //Set the API Action to execute the report
    myApi.Action = wrApiAction.ExecuteReport;
  5. //Call GetUrlParamString() to close the session and retrieve the URL for it
    string url = netApi.GetUrlParamString(homePage);

REST Web Service API

To use REST, create the session and pass the session variables. Take note of the sessionId and UrlParamString.

POST /sessions


 "Page": homePage,
 "ApiAction": "ExecuteReport",
 "ExportType": "Html",
  "ReportPath": reportPath

Response (some params omitted):

 "sid": sessionId,
 "AppUrl": urlParamString


There are four provided GetExecute methods. Each return a different data representation of the report. Not every API supports every data type; see the Overview for details.

  • GetExecuteHtml: Typically used for web viewing
  • GetExecuteCsv: Plain-text format readable by spreadsheet applications
  • GetExecuteData: Byte array of binary data
  • GetExecuteJson (v2016.3+): Typically used for asynchronous client-server communication

Since GetExecute does not require loading the Exago UI, calling GetUrlParamString is not required. Report interactivity is also not supported when executing reports via the GetExecute functions. However, the following Server Events are triggered in order to ensure that the data returned accurately reflects the report design:

See the following sections for examples. Variable names and arguments are placeholders.


  1. //First create an API session and load a report object.
    Api myApi = new Api(appPath);
    Report myReport = (Report)myApi.ReportObjectFactory.LoadFromRepository(reportPath);
  2. //Then call the appropriate GetExecute() method for the desired data type.
    string reportHtml = myReport.GetExecuteHtml();

REST Web Service API

When using the REST Web Service API, the initialization call creates a session ID string, which is a required URL parameter in all subsequent method calls. Note that the session URL is generated immediately, and altered dynamically as modifications are made to the session.

  1. First create an API session. Take note of the session ID.POST /sessions

    Response (some params omitted):

     "Id": sessionId
  2. Then execute the selected report. Supported types are HTML, CSV, PDF, RTF, Excel, JSON.POST /reports/execute/{type}?sid=”sessionId”


     "ReportPath": "InventoryCategories",
      "DataType" : "Data"

    Sample Response:

    Status: 200 OK
      "ReportPath":  "InventoryCategories",
      "ExportType":  "csv",
      "DataType":    "Data",
      "ExecuteData": ""Categories"rn"Seafood"rn"Produce"rn"Beverages"rn",
      "IsError":     false,
      "ErrorList":   null
