I have a utility to access my dropbox account and pull files from the drop box and load it into my application. How do I go about doing that?
You can get an API app key and secret (a.k.a. consumer key and secret) by creating a Core or Sync API app at:

Note that Drop-ins do not have app secrets.
Once you have an app created, the app key and secret will be available by going to the App Console and selecting the app here:

Once you have an app key and secret you can use the API to list/download/upload files. We recommend using one of the official SDKs if possible:
