Solved: Execute a workflow with REST API

CalmCloud · ‎02-06-2015

Hi All,

I am not able to execute the workflow with REST api.

POST https://<<HOST>>:<<PORT>>/api/workflows/94dd5f20-c190-4023-a0a7-1589c46f3792/executions/

following is the response. VCO does not have any work flow runs so I assumed nothing was executed. I can run https://wxpcpvcd006a:8281/api/workflows/f29ebe52-27b2-42d1-84f1-6ecfb939326c to get all the info about the workflow. Any help appreciated.

My article steps you through the process of calling workflows with REST: http://bit.ly/restvco - you should certainly see a workflow execution when you have completed the call properly.

Hi Burke,

I followed your blog. It works fine with GET request like getting workflow executions, definition etc. It does not work for running workflows - POST request. I noticed POST to run workflow get 301 redirect for GET. I am running VCO 5.5.1 version.

Attached are screenshots.

iiliev · ‎02-06-2015

In vCO 5.5.x and up, the URLs of REST API requests have been changed a bit

Instead of

https://[host]:[port]/api/...

they now look like

https://[host]:[port]/vco/api/...

That's one of the reasons you get 301 redirects.

I have tried /vco ,it throws 400 error with.

VCO was recently upgraded to 5.5.1.

Which means your POST request body is not properly formatted. Could you show the exact XML or JSON body content?

CalmCloud · ‎02-06-2015

I want to get simple workflow working so workflow does not have any inputs so there is no json body.

Attached is chrome plugin postman. It shows only get and delete are allowed.

iiliev · ‎02-06-2015

Yes, POST is not supported on https://[host]:[port]:8281/vco/api/workflows/[workflow-id] (the URL I see on the screenshot)

To start the workflow, you need to POST to the following URL

https://[host]:[port]:8281/vco/api/workflows/[workflow-id]/executions

I get same error.

I might have to update REST plugin. I will update after that.

Burke- · ‎02-06-2015

Even a simple workflow with Zero inputs still requires a body when doing a post...
