curl https://api.unifapi.com/linkedin/posts/{id} \
-H "Authorization: Bearer $UNIFAPI_KEY"Parameters
- idpathrequired
- The id path parameter for this LinkedIn operation. Use the URL-visible slug or id described in the docs.
- The parameter for this LinkedIn operation. Use the URL-visible slug or id described in the docs.
This operation is part of the LinkedIn API in the social platforms category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.
Use it when a workflow needs LinkedIn public data but should still keep one API key, one account balance, and one predictable JSON contract across social, live public-data sources.
Common agent workflows
- Fetch canonical public LinkedIn content for summarization, ranking, monitoring, or enrichment.
- Attach engagement, author, media, and source metadata to an agent workflow.
- Give an AI agent a stable LinkedIn data source without building a per-platform integration.
- Normalize LinkedIn responses into the same UnifAPI envelope used across the catalog.
Unified envelope, platform-native fields
- Lookup responses return one canonical object in `data` with stable identifiers, source URLs where available, and platform-specific metadata normalized into predictable JSON.
- The `billing.records_charged` field reports the charged billable-record quantity for the successful response.
- A not-found or invalid-input condition uses the unified UnifAPI error shape, so callers do not need special handling for each source platform.
Response status codes
Billing
This operation charges 1 credit per billable record, with a 1 credit ($0.001) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.
Errors and retries
Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.
