List client entities
Returns clients (entities) for the practice—typically companies and individuals you onboard.
Use lastUpdated for incremental sync and pageNumber for paged exports (1-based, up to 10000).
Optional name, otherName, surname, and email query parameters apply case-insensitive substring filters (AND together when more than one is set).

Authorizations
Swagger / Postman only: Client ID as username, Client secret as password. In Postman, set this once on the collection (Authorization → Basic Auth) so all requests inherit. For production server-to-server code, prefer X-OM-Auth-ID and X-OM-Auth-Key headers.
Query Parameters
Only entities changed on or after this UTC time (incremental sync).
1-based page index (1–10000).
Substring match on entity first/given name (afEntityName).
Substring match on other/trading name (afOtherName).
Substring match on surname (afEntitySurname).
Substring match on email (afEntityEmail).
Response
OK
Friendly or preferred name for the client (not an honorific title such as Mr or Ms).
