title: AEM Workflow custom input data
body: <p>I need to create a workflow in AEM that for a page (specified as payload) finds all the assets used on the page and uploads a list of them to an external service. So far I have most of the code ready, but business process requires me to use a special code for each of the pages (different for each run of the workflow), so that the list is uploaded to correct place.</p>
  
  <p>That is when I have a question - <em>Can you somehow add more input values for an AEM workflow?</em> Maybe by extending the starting dialog, or adding some special step that takes user input? I need to be able to somehow specify the code when launching the workflow or during its runtime.</p>
  
  <p>I have read a lot of documentation but as this is my first time using workflows, I might be missing something really obvious. I will be grateful for any piece of advice, including a link to a relevant piece of docs.</p>
