QPR ProcessAnalyzer API's can be used to automate operations in process mining or create integration with other applications. QPR ProcessAnalyzer has two API:

  • Web API: REST-based API used by the web UI.
  • WCF API: Older API used by the Excel Client and ScriptLauncher.

Prefer the Web API, because WCF API is a legacy API that will be removed in future.

Web API

The Web API is based on the REST principles and it uses JSON. All operations require a login which is done with the Token operation with username and password.

Url has the following form:

http(s)://customer.onqpr.com/qprpa/api/operationName
  • Token: Login user using username and password, and get a session token as a response.
  • Sign out: Logs out a session.
  • Analysis: Run query in the server and returns results as a response.
  • Cancel: Cancels currently running operation.
  • Filters: Get all filters in system or filters in a model.

WCF API

All WCF API operations only accept HTTP POST method (HTTP GET is not allowed). WCF API can be used with wsHttp (SOAP) and webHttp endpoints.

The following methods are available in the WCF API:

PowerShell Examples

Move Data from QPR ProcessAnalyzer to Database using PowerShell

List Users

$paService=New-WebServiceProxy –Uri "http://localhost/qprpa/MainService.svc"
$connection=$paService.Authenticate("username", "password", @())
$token=$connection.GetValue(0).Value

$param=@()
$users=$paService.GetUsers($token, $null, $param)
$users
$paService | get-member | ? {$_.definition -match "GetAnalysis"}

Update Model Configuration

$paService=New-WebServiceProxy –Uri "http://localhost/qprpa/MainService.svc"
$connection=$paService.Authenticate("username", "password", @())
$token=$connection.GetValue(0).Value
$param=@()
$modelId=@(2)
$model=$paService.GetModels($token,$modelId, $param)

$model[0]
$model[0].ConfigurationJson = "{}"

$paService.SetModel($token,$model[0], $param)

Get Flowchart Image

$paService=New-WebServiceProxy –Uri "http://localhost/qprpa/MainService.svc" -Namespace "WebServiceProxy" -Class "PaService"
$connection=$paService.Authenticate("username", "password", @())
$token=$connection.GetValue(0).Value

$ids = new-object WebServiceProxy.ModelViewId
$ids.ViewId = 13
$ids.ViewIdSpecified = 1

$analysisType = 0
$processAnalysisType = 4
$minTransitionPercentage = 0.0

$png=  $paService.GetAnalysisImageAsByteArray($token, $ids,  $analysisType,1,  $processAnalysisType,1 , $minTransitionPercentage,1)
[IO.File]::WriteAllBytes('c:\tmp\image.png', $png)
