Spec Documentation for Details
Requests a tuple of the changed details since the given version (version will always be set in the output but all other fields are optional - only reported if they changed).
- previousVersion (int)
The version returned by the last call to this function. Passing 0 will return all the data (version 0 can never be returned).
- callbackUrl (stringUrl)
A Url the receiver will call to notify us that there is some data to poll. Note that the receiver is free to ignore this (out of trust, load issues, or other).
