To run The Mission Dock you need to add two parameters to
NickelledSettings – userId and missionDockId.
We supply the missionDockId with your code snippet.
The userId is a unique reference to each user on your website that you provide.
Typically this is...
a number (e.g. 123) or
a UUID (universally unique id) (e.g. 66a6a94c-0c14-47aa-95a9-8b176b8add76) or
an email address (e.g. email@example.com)
Important - the user Id is provided by your application and isn't your Nickelled userId
If you don't know what this is talk to your developers or IT people and they would be able to set it up for you.
