I want to start SharePoint Designer 2010 workflow from Nintex Online workflow. Also while starting the workflow, I have to pass few Initiation parameter to the SPD workflow. In Nintex Online Start Workflow action, there is no option to pass initiation parameters.
Is there any way I can pass parameter to SPD 2010 workflow?
You should be able to do this using a web service.
The SharePoint workflow.asmx webservice contains a method, "Start Workflow".
Requires you to pass in the item url, the workflow guid and any parameters the workflow requires.
This article is for SharePoint 2007, but the web service still exists for SharePoint 2016 and O365.
