bug-fixAdded a quick-find action that looks up candidates, contacts, companies, jobs, leads and opportunities by name, email, phone or ID in one call, and corrected tool guidance so agents pick dedicated actions over generic ones and know that requesting all fields is refused.

​
12 Oct 2026
new-actions bug-fixAdded tearsheet (shortlist and hot list) management, file attachment listing and content retrieval, and remote-work fields on job orders, and corrected search and query guidance on dates, ID ranges, page sizes and child-record lookups to prevent silent empty or wrong results.
bullhorn_add_tearsheet_candidates, bullhorn_add_tearsheet_client_contacts, bullhorn_add_tearsheet_job_orders, bullhorn_create_tearsheet, bullhorn_get_file_content, bullhorn_get_tearsheet, bullhorn_list_entity_files, bullhorn_list_tearsheets, bullhorn_remove_tearsheet_candidates, bullhorn_remove_tearsheet_client_contacts, bullhorn_remove_tearsheet_job_orders, bullhorn_update_tearsheet

​
24 Sept 2026
bug-fixClarified search versus query usage per entity (including tearsheets), supported search syntax and wildcards, decimal range filters, entity-specific fields and associations, and that client corporations cannot be deleted, preventing invalid-request errors and silent empty results.
bullhorn_list_associated_entities, bullhorn_list_candidates, bullhorn_list_client_contacts, bullhorn_list_client_corporations, bullhorn_list_job_orders, bullhorn_list_job_submissions, bullhorn_list_notes, bullhorn_list_opportunities, bullhorn_list_placements, bullhorn_list_searchable_fields, bullhorn_list_tasks, bullhorn_query_entity, bullhorn_search_entity, bullhorn_search_entity_large_query, bullhorn_update_client_corporation
​
15 Sept 2026
bug-fixClarified how to set association fields such as owner when mass-updating records, preventing invalid-request errors from incorrectly formatted field values.
bullhorn_mass_update_entity
​
10 Sept 2026
data-sync improvementAdded data sync support to candidate, client contact, client corporation, job order, job submission, note, opportunity, placement, task, and appointment list actions, so their records can be periodically pulled and kept up to date, with paging handled automatically and results ordered by ID for reliable pagination.
bullhorn_list_appointments, bullhorn_list_candidates, bullhorn_list_client_contacts, bullhorn_list_client_corporations, bullhorn_list_job_orders, bullhorn_list_job_submissions, bullhorn_list_notes, bullhorn_list_opportunities, bullhorn_list_placements, bullhorn_list_tasks
​
8 Sept 2026
bug-fixFile downloads now return base64-encoded content that decodes to the exact original file, and appointment date fields include clearer guidance for computing millisecond timestamps.
bullhorn_create_appointment, bullhorn_download_file, bullhorn_update_appointment
​
4 Sept 2026
new-actions auth breakingAdded opportunity management, file and resume parsing, generic entity read/write, batch reads, searchable-field introspection, and a non-interactive OAuth 2.0 login option. The appointment list action now filters with JPQL where clauses instead of Lucene queries, and the non-functional delete client corporation action was removed (Bullhorn does not support deleting client corporations - archive them via update instead).
bullhorn_create_entity, bullhorn_create_job_order, bullhorn_create_opportunity, bullhorn_delete_entity, bullhorn_delete_file, bullhorn_delete_opportunity, bullhorn_delete_placement, bullhorn_download_file, bullhorn_get_entities, bullhorn_get_opportunity, bullhorn_list_associated_entities, bullhorn_list_opportunities, bullhorn_list_options, bullhorn_list_searchable_fields, bullhorn_mass_update_entity, bullhorn_parse_resume_to_candidate, bullhorn_query_entity, bullhorn_search_entity_large_query, bullhorn_update_entity, bullhorn_update_opportunity, bullhorn_upload_file

​
2 Sept 2026
bug-fixFixed appointment listing by routing it through Bullhorn’s query API with JPQL filtering and sorting, and added clear validation errors when update requests contain no fields to update.

17 Aug 2026
