How It Works

A simple 4-step flow to get your product connected and messaging via LinkedAPI.

Create an account & get a scoped key

Sign up and generate a scoped API key with limits tailored for development or production. Keys are scoped by capability and environment so you can safely test without impacting production traffic.

  • Scoped permissions: grant only the access your integration needs (messages, profiles, admin). Scopes are enforced server-side and can be adjusted without redeploying clients.
  • Environment separation: create separate keys for dev, staging, and production to isolate usage, logs and billing.
  • Key management: built-in rotation, expiry, and audit logs make it easy to maintain security and demonstrate compliance.

Install SDKs & authenticate

Use official SDKs for Node, Python, or Go to handle requests, retries, pagination and structured responses. Authenticate with your scoped key or exchange it for short-lived tokens for session-based flows.

  • Prebuilt clients: typed responses, automatic backoff and standardized errors reduce boilerplate and make integrations more resilient.
  • Auth patterns: support for API keys, OAuth user-bound flows and token rotation for long-running services and multi-tenant apps.
  • Quickstarts & samples: example apps, CLI tools and Postman collections get you from install to first API call in minutes with copy-paste ready snippets.

Map profiles & workflows

Connect LinkedIn profiles, map messaging threads to your internal models, and define automation triggers for onboarding, follow-ups, lead routing and CRM sync. Conversation context and identity mapping are preserved so user-facing histories remain accurate.

  • Profile linking: deterministic matching, fuzzy heuristics and webhook updates keep profiles synchronized and prevent duplicates.
  • Thread & message mapping: persistent thread IDs, metadata and timestamps enable accurate aggregation and search across systems.
  • Idempotent automation: built-in deduplication tokens, checkpoints and transactional steps let you retry safely without creating duplicate messages or actions.

Monitor & scale safely

Get visibility into delivery, failures and performance so you can scale confidently. Use rate controls, regional failover and policy-based automation to protect accounts and recipients while meeting global demand.

  • Observability: real-time logs, message traces, delivery receipts and webhook diagnostics for fast root-cause analysis and replay.
  • Rate & policy controls: scoped rate limits, soft-limits and priority queues help you stay within platform and recipient policies while maximizing throughput.
  • Reliability features: automatic retries with jitter, regional failover, SLA-backed routing and integrations with PagerDuty / Slack for alerting and incident response.

What teams say

Engineers and product teams scale faster with LinkedAPI — a unified API that streamlines LinkedIn messaging, profiles, attachments, webhooks, SDKs, and enterprise controls so teams can move from prototype to production with confidence.

"LinkedAPI reduced our integration time from weeks to hours. Reliable webhooks and clear SDKs made all the difference."

How it helped: streamlined event delivery and SDK-driven examples removed guesswork during integration — we shipped faster and more reliably.

  • Reliable webhooks
    Instant event delivery with retries, idempotency keys, and clear delivery logs for debugging.
  • Multi-language SDKs
    Production-ready examples and auth flows for Node, Python, and Go to get you past the first request quickly.
— Anya Patel, VP Engineering, AcmeCloud
"We now surface LinkedIn conversations directly inside our CRM with full threading and attachments."

How it helped: full conversation context and media support allowed our reps to see complete history and attachments without switching systems.

  • Full message threading
    Conversation IDs, timestamps, and participant metadata preserved so threads map directly into CRMs.
  • Attachments & media
    Support for images, PDFs and other media types with secure URLs and metadata for display and storage.
  • Unified mapping
    A single API surface maps LinkedIn entities to your CRM objects, reducing transformation code and edge cases.

"Enterprise-grade controls and regional failover gave us the confidence to move to production quickly."

How it helped: security, compliance and availability features matched our requirements for customer data and uptime across regions.

  • Access controls & audit logs
    Role-based permissions, API keys, and detailed audit trails for compliance and governance.
  • Regional failover & HA
    Multi-region endpoints and automated failover to meet availability targets and keep message flow uninterrupted.
  • SLA & support
    Commercial SLAs, onboarding assistance, and priority support for enterprise launches.
