Answering userInteractionID with REST call not working

[SatishPatil]

Hi All,

My usecase is to stop workflow till it is approved/rejected by external system(servicenow). The workflow is using "User Interaction" to wait for approval/rejection of the request. The external system(servicenow)  makes REST call to the flow. I am following the link "http://pubs.vmware.com/vsphere-51/index.jsp#com.vmware.vsphere.vco_develop_web_services.doc/GUID-AF6..."

As per the link make a POST request to the user interaction instance for the particular workflow execution:

POST https://{vcoHost}:{port}/api/workflows/{workflowID}/executions/{executionID}/interaction/

I am making POST to /api/workflows/2700308b-ea6c-4c40-ae64-99ef97fb8154/executions/ff80808147b7443e014813261fb92d62/interaction/

with the request body

<execution-context xmlns="http://www.vmware.com/vco">

   <parameters>

     <parameter name="Status" type="string">

       <string>Approved</string>

     </parameter>

   </parameters>

</execution-context>

where 2700308b-ea6c-4c40-ae64-99ef97fb8154 -> workflow id & ff80808147b7443e014813261fb92d62 -> running instance id.  Is it required to pass UserInteractionID ?

It returns the following

<Response xmlns="https://labvcot30.entdev.addev.ntrs.com/vco/api/workflows/2700308b-ea6c-4c40-ae64-99ef97fb8154/execu...">

Any help appreciated.

Satish, is this vCO 5.1 or 5.5.x? It looks like you are answering interaction using 5.1 style URL but your vCO server is in fact 5.5.x

• URLs in the response XML are 5.5.x style URLs (/vco/api/... instead of /api/...)
• Answering interaction should return status 204 (no content) on success
• Could you double check if execution ID is correct?

If this is vCO 5.5.x, I'd recommend first to check POST to

  POST https://{vcoHost}:{port}/vco/api/workflows/{workflowID}/executions/{executionID}/interaction/

instead of

  POST https://{vcoHost}:{port}/api/workflows/{workflowID}/executions/{executionID}/interaction/

(note the /vco part after the port).

Thanks llian for the response.

We are on 5.5. 

The API doc on 5.5 has the following url for answering user interaction.

http://<host>:<port>/api/workflows/{workflowId}/executions/{executionId}}/interaction/presentation/instances/{presentationExecutionId}

I got  the presentationExecutionId by executing  https://xxxx.com:8281/vco/api/catalog/System/UserInteraction?status=0. It returned 5 responses. I was interested in the following user interaction object. I got the presentationExecutionId(ff80808147b7443e0148182e448f2ff5) from the following

      <e>

         <attributes>

            <e>

               <name>id</name>

               <value>ff80808147b7443e0148182e448f2ff5</value>

            </e>

            <e>

               <name>description</name>

            </e>

            <e>

               <name>name</name>

               <value>Linux Stub : SNApproval</value>

            </e>

            <e>

               <name>state</name>

               <value>waiting</value>

            </e>

            <e>

               <name>createDate</name>

               <value>2014-08-27T10:55:58.479-05:00</value>

            </e>

            <e>

               <name>type</name>

               <value>WorkflowInput</value>

            </e>

         </attributes>

         <href>https://xxxxxx.com:8281/vco/api/catalog/System/UserInteraction/ff80808147b7443e0148182e448f2ff5/</href>

         <rel>down</rel>

      </e>

The following REST is executed to answer user interaction.

POST https://xxxxxxx.com:8281/vco/api/workflows/2700308b-ea6c-4c40-ae64-99ef97fb8154/executions/ff8080814... HTTP/1.1

User-Agent: Fiddler

Host: xxxxxx.com:8281

Content-Length: 266

Accept: application/xml

Content-Type: application/xml

Authorization: Basic c3AxNDhAZW50ZGV2LmFkZGV2Lm50cnMuY29tOlBAdGlsMQ==

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

<execution-context xmlns="http://www.vmware.com/vco">

   <parameters>

     <parameter name="Status" type="string">

       <string>Approved</string>

     </parameter>

   </parameters>

</execution-context>

Now the response is http 404 "Execution not found for execution id: ff80808147b7443e0148182e448f2ff5"

Any help appreciated.

Interaction ID is not the same as execution ID.

I have to check what exactly is written in the official documentation, but I think you can answer the user interaction by POST-ing to

  https://<host>:<port>/vco/api/workflows/{workflowId}/executions/{executionId}/interaction/

not to

  http://<host>:<port>/vco/api/workflows/{workflowId}/executions/{executionId}}/interaction/presentation/instances/{presentationExecutionId}

and as execution id, pass the workflow execution id.

(You can get this URL as a link href if you get the interaction as <user-interaction> object from the <inventory-item> object from GET https://xxxxxx.com:8281/vco/api/catalog/System/UserInteraction/ff80808147b7443e0148182e448f2ff5)

Thanks llian.

I am able to get it working by posting to the url https://<host>:<port>/vco/api/workflows/{workflowId}/executions/{executionId}/interaction/
