Join us as we cover some of the roadblocks that many admins face when implementing a Flow, and how to overcome them using a bit of code. We will cover passing data to the Flow, modifying styling of the Flow interface using Visualforce, changing the finish location using Apex, and discuss adding attachments within a Flow using Apex and Javascript. We'll provide admins and beginning developers with "just enough" code to get them past these common roadblocks to make their Flows stellar. No programming experience necessary, but participants should be familiar with building a Flow as that will not be covered in this session.
