In this chapter, we have gone through various concepts related to debugging the Flow. In the beginning, we have seen who can run the Flow and the permissions required for it. We also covered various ways to call a Flow. We have also discussed ways to set Flow variables' value from the controller and ways to open Flow access for non-Salesforce users. Then, we moved forward and discussed ways to access a Flow from Salesforce1 and how to use a Flow though an Inline Visualforce page. Finally, we discussed key points related to manipulating the data. In the next chapter, we will discuss Process Builder and how this will help you to automate your complex business process, for example, auto submitting records into Approval Process, and so on.
