The SDK appears to be useful.
We’ll need to change what we’re requesting from the OAuth dance to the
account_id, assuming that’s available.
See the SDK Spike.
We are assuming that the account_id is not a secret and so should be
logged/kept in the clear.
Notably the SDK has a pagination iterator. We’ll just need to figure out the bookmarking strategy for it. Default to writing a bookmark for every record?
