Conditional running of workflows in Gallery

Question

Dear Friends,

I was using CReW list runner/conditional runner quite a bit in my previous projects to chain workflows together. Now I am learning gallery APIs and would like to know if we could have a similar solution that we can chain the workflow in gallery together.

What I understand is when working with gallery API, if we call the workflow execute endpoint, the response will show the job is queued and we need to periodically call the job run status endpoint to get the job status.

I would like to learn if there is an event-driven approach to chain the workflows - i.e. if the 1st wf completes, the 2nd wf will be triggered automatically.

Thanks!!

Thank you Dan. I have been using CReW macros on gallery as well. The only thing is my support team came to me recently and said if I use CReW, they will not be able to get all the logs in the server log table and also as CReW is executing the Alteryx Engine, they are not like other jobs submitted/scheduled via gallery - basically they are saying running workflows via CReW runners will let things out of control.

@MarqueeCrew - it would be great if you could provide your comments on pros/cons for using CReW runner macros on gallery/server.

Thanks

When Alteryx says that the CReW runner macros are not supported on the gallery, what they're saying is that if you use one of the runner macros in a workflow. they'll only help out in a support case if the workflow is  running in Designer.  If the workflow is running on a server then you're on your own.  You can always turn to the Community for help.

I haven't found a case where they say that the runner macros are not "recommended" on the gallery, only that they're not supported.  I've used the runner macros on our gallery in the past with no issues

@MarqueeCrew is the expert on the CReW macros and their use on the gallery, and can correct me if needed

That being said, the runner macro is probably the way to go in your case

Thanks Dan. Looks like I have to create another monitor workflow as you mentioned.

So if I come back to my initial requirement - I need a mechanism to ensure the workflows run in sequential. Would you recommend we use CReW or we use API + a monitor workflow? It seems to me the latter approach is too much and also it waste a lot if time slots for waiting.

Thanks
