This is a question regarding uploading attachments during a manager approval task (Request Data). If I'm understanding correctly, the only way to upload a workflow attachment to SharePoint is by using the custom action found in this link:
It seems when the approval manger attaches a document during their approval task, that document is only saved as a URL in a workflow variable of your choosing. That URL then needs to be extracted using the custom action and dropped into SharePoint. Am I on the correct path here? I'm very new to Nintex so my understanding may be limited. Any assistance is much appreciated!
