🔁 ID mapping endpoint

Since the IDs of Employee API will not be the same as Base Employee API, we've prepared a mapping endpoint for mapping purposes. This means that the valid, non-duplicate data you already have can be used in the Base Employee API. The mapping endpoint is listed below:

Action	Endpoint
Map Old to New	/v1/professional_network/employee_base/map/ids

---

📩 Bulk Collect endpoints

Note: id_file is no longer supported — use ids array instead. Recommendation: Add this clause to target non-duplicate records:

 "term": {
            "is_parent": 1
 }

Action	Employee API Endpoint	Base Employee API Endpoint
Bulk Collect by IDs	/v1/professional_network/member/bulk_collect/id_file	/v1/professional_network/employee_base/bulk_collect/ids ❗

Bulk Collect

⚠️ Bulk Collect limit

Release date: April 2, 2025

New rule: A single Bulk Collect request cannot retrieve more than 10,000 profiles. This applies to:

• ID list uploads

• Filter-based requests

• Elasticsearch DSL-based requests

Error handling:

Code	Scenario	Message
400	ID list exceeds 10,000 profiles	File contains too many IDs. Maximum is 10,000 IDs
422	Filter results exceed 10,000 profiles	Request matched too many IDs. Maximum is 10,000 IDs
422	ES DSL results exceed 10,000 profiles	Request matched too many IDs. Maximum is 10,000 IDs

Behavioral notes:

• ID list violations block request creation immediately.

• Filter/Elasticsearch DSL overages are rejected after request creation, during processing.

  • Clients are notified via webhook (if webhook_url was provided).
