Steps
Authenticate with HTTP Basic Auth or a Bearer personal access token as with any Core API call
Call the Search Matters endpoint with URL-encoded or JSON query parameters — this endpoint is generally available and not restricted to Premium subscribers
Call Get Matter Details with a specific matter UUID in the path to retrieve full details, including Assignment, Charge, Income, Litigation, and Service subtable records by default
Use the literal lowercase string %empty% as a filter value to search for fields that are null, since a blank query parameter is silently ignored
Request custom fields explicitly if needed — optional custom fields are excluded from Search/Get responses by default
Respect the 200 requests/minute rate limit and back off using the x-rate-limit-remaining and x-rate-limit-reset response headers
Known gotchas
A blank query parameter (e.g. office=) is silently dropped rather than filtering for blank values — you must send the literal string %empty% to search for null/empty fields
Optional custom fields are excluded from Search/Get Matter responses by default even though they exist on the record
Case Restrictions (Office/Program/Case-level access controls) can cause a restricted matter to simply be omitted from search results while a direct Get Matter call for the same UUID returns a 403 — the two endpoints don't fail the same way
