Is there a way to use the context-sensitive process launcher from a web applicat

Hi Moritz - What is the web application outside of Appian? Is this some other portal or custom built application? Most likely what you will need to do is make a web services call from the external app to create a new process in Appian. What context do you need in the other application?

Hi Ryan. It's a custom build web solution. Ideally we want to add a link to it, which invokes a start form of a process and passes an ID to the start form. Based on the ID we want to prefill some values of the form. I know that it's possible to invoke the form without parameters through a URL, but is it also possible to pass a parameter in the URL? Thanks, Moritz
