LinkedIn Data API

Read member and company profiles, posts, job details, job search results, and comments through 13 authenticated LinkedIn Web V2 endpoints.

Authentication

Send your API Hop API key in the Authorization header. Access depends on enabled gateways and your key permissions; documentation does not confirm production availability.

Authorization: Bearer YOUR_API_KEY

Requests

Synchronous operations use GET query parameters without a body. Unknown fields and duplicate scalar fields are rejected. Only fields marked as arrays accept repeated keys, for example company_ids=1035&company_ids=1441. Preserve IDs and cursors as strings; do not convert large identifiers to JavaScript numbers. Optional empty values are omitted.

curl --get "https://api.apihop.ai/v1/linkedin/web-v2/users/profile" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  --data-urlencode "url=https://www.linkedin.com/in/williamhgates/"

Billing

For synchronous operations: Member profiles, company profiles, and post details cost $0.008 (8000 credits) per successful request. The other five operations cost $0.05 (50000 credits). These are default customer prices; account-specific prices take precedence. Every requested page is billed separately, not per item. Upstream failures release the reservation. Settlement failures do not trigger another upstream call.

Pagination and limits

For synchronous operations: Member posts return only the latest 50 items: start and pagination_token have no effect, even when the response contains a token. Company posts use start=0, 50, 100, ...; pagination_token has no effect. Job search uses start=0, 25, 50, .... Comments support page (starting at 1) and pagination_token. There is no automatic pagination. Requests time out after 60 seconds with no automatic retries. The supplier warns that resource constraints can cause intermittent failures.

Scope

Eight synchronous Web V2 operations and five asynchronous task operations are available. Create profile, company, or post tasks with POST and a JSON url field. Creation returns HTTP 202 and a decimal platform task ID as a string. GET status and result reads require the same tenant and are free; unknown, foreign-tenant, and other-product tasks return 404. Status omits result; result is null before COMPLETED. Each task reserves its price at creation and charges once on success ($0.008 / 8000 credits by default). Failure or a 30-minute timeout releases the reservation. Background polling runs every 5 seconds; pending responses include Retry-After: 5. Results are stored in the platform job. Use the platform ID, never a supplier task ID. An uncertain submission is not automatically repeated. A completed task returns result.records. Integers beyond the JavaScript safe range are stored and returned as decimal strings. Examples are illustrative, not live acceptance results.

Responses

For synchronous operations: The native JSON code/data envelope and numeric precision are preserved. Response shapes vary by operation. HTTP 200 alone is not success: business errors, including error/error_code records, are rejected. A successful empty result is billable. This is an illustrative response, not a live acceptance result.

{"code":200,"data":[]}

Errors

HTTP 400: invalid parameters; 401: invalid authentication; 402: insufficient credit; 403: denied gateway access; 405: unsupported method; 408: cancellation; 429: rate limit; 502/503/504: supplier failure, unavailable configuration, or timeout. Keep X-Request-Id for troubleshooting.
