List client contacts
Returns contacts linked to clients in your practice. Each row is an entity contact — a person tied to one client (entityKey).
Use lastUpdated for incremental sync and pageNumber for paged exports (1-based, up to 10000).
Optional entityKey limits results to one client. By default, soft-deleted contacts are excluded; set includeDeleted=true to include them.

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 contacts changed on or after this UTC time (incremental sync).
1-based page index (1–10000).
When set, only contacts for this client entity key.
When true, includes soft-deleted contacts.
Response
OK
