LinkupAPI
What is LinkupAPI?
LinkupAPI is a unified B2B API platform that gives AI agents and business applications access to LinkedIn engagement, WhatsApp messaging, real-time web crawling, professional email discovery, contact enrichment, company data, and buying signals. It provides more than 50 endpoints for activities such as sending LinkedIn messages, managing invitations, interacting with posts, finding and verifying emails, extracting company information, monitoring job postings, and identifying real-time intent signals. The platform is designed for sales, recruitment, CRM enrichment, no-code automation, and AI-agent workflows.
How to use LinkupAPI?
Create an account, retrieve an API key, review the documentation, and connect the required LinkedIn or other B2B accounts. Use the available REST API endpoints by sending requests with your API key and the necessary account credentials or login token. You can then build prospecting, enrichment, messaging, web extraction, recruitment, or AI-agent workflows, or connect LinkupAPI with no-code tools such as Make and n8n. API usage consumes credits according to the endpoint and action performed.
