This Web method is used to execute a pending Activity (those found at the Inbox) from an external application.

In this way, the Activity is completed and that given case proceeds to the next stage in the workflow.


This method receives a single input having mainly: The information of the end user executing the Activity, the specific Process instance to be worked on (case number), the given Task name representing the pending Activity, and any business information relevant to that Activity (any data, attachments, etc).

Through this method, a pending Activity is completed, in the same way as it would be done at the Work Portal.

For further information about completing work from the Work Portal options, please refer to Bizagi Work Portal.




The description provided in this article applies too for the performActivity web method available in Bizagi .NET edition.

For the performActivity method, the request and response XML's are of the native .NET XmlDocument type.

For the performActivityAsString method the same XML structure is handled, but this parameter is sent as a string type.





Input Schema

The following shows a sample XML structure of information to send to Bizagi:


<?xml version="1.0" encoding="utf-8"?>

<xs:schema xmlns:xs="" elementFormDefault="qualified" attributeFormDefault="unqualified">

 <xs:element name="BizAgiWSParam">



                         <xs:element name="domain" type="xs:string"/>

                         <xs:element name="userName" type="xs:string"/>

                         <xs:element name="ActivityData">




                                                         <xs:element name="idCase" type="xs:integer"/>

                                                         <xs:element name="radNumber" type="xs:string"/>



                                                         <xs:element name="taskId" type="xs:integer"/>

                                                         <xs:element name="taskName" type="xs:string"/>





                         <xs:element name="Entities">








Input Parameters

BizAgiWSParam: Root node, containing all the necessary information to execute the Activity.

domain: Here goes the name of the domain for the Bizagi user who will be register as performer of the executed Activity.

userName: Name of the user who will be register as performer of the executed Activity.

ActivityData: Contains all the necessary information to find an Activity.

idCase: Is the case identification number for the Activity which wants to be performed. It is required to include this element or the radNumber.

radNumber: An alternative to the idCase. It is the creation number (case number) of the case containing the pending Activity that wants to be continued. When the same creation number is used for several cases (like when a Sub_process uses its parent’s number) the idCase must be used to distinguish for which case the Activity belongs to.

taskId: It is the identification number for the Activity which wants to be executed. This element is necessary; if this number is not known then the taskName must be included.

taskName: Use as a complement or alternative to taskId, it is the name of the pending Activity which wants to be executed.

Entities: It is a node containing the values for the business data that is going to be set for the case.

For further information about the expected structured for the business information contained in this Entities element, refer to Bizagi's data model XML schemas.



Input Example

With the following sample XML, we will complete the Activity with Task name = Task3, for the case number having identifier = 9253.




If you wish to follow a detailed business example using the performActivityAsString Web method, refer to how to perform an Activity in Bizagi from other applications.
