## About GTM API
GTM API is ready-made GTM infrastructure. A single, typed API gives AI agents (Claude, ChatGPT, and others) and backend systems programmatic access to LinkedIn, email, and calendars. It is not just another sequencer; it is the execution layer for your pipeline: your agent sends invites and messages, manages the inbox, and streams events back into your stack. Connect three ways: MCP (Model Context Protocol) for AI agents, REST APIs for backends, and webhooks for event-driven workflows. Works with Claude, ChatGPT, LangChain, n8n, Make, Zapier, and custom stacks. Channels: LinkedIn, email (Gmail, Outlook, IMAP), and calendar sync (Google, Microsoft, iCal). Capabilities: • Messaging: direct messages, Sales Navigator messages, InMails • Connection requests and invitations • Post engagement: tracking, commenting, liking • Profile and company search with enrichment • Audience mining: likers and commenters Safety by design, the safest LinkedIn stack: Single Session Protection (one active session per account), cloud anti-detect browser infrastructure, rotating sender profiles, dedicated residential proxies, smart warm-up curves and rate limiting, and device fingerprinting. The result: 20,000+ LinkedIn accounts operated at under a 1% ban rate, versus an industry where roughly 80% of automation users get restricted in their first year. Built for: • GTM engineers connecting agents to outreach workflows • Agencies onboarding clients safely with OAuth, no password sharing • Platform builders embedding channels in their own product • Account providers managing and leasing account fleets with access controls and warm-up Example workflows: scrape post engagers, enrich, filter by role and company, export leads; triage unanswered messages and auto-draft replies; event-based outreach (SaaStr attendees, job changes); track competitor audiences and dedupe against your CRM; run multi-account mass actions with intelligent pacing; classify inbound replies and route hot leads to HubSpot.
