Unipile
Unipile is a unified API designed to integrate multiple communication channels, messaging, email, calendar, and more, into your software application. It provides over 500 endpoints that enable developers to connect platforms such as LinkedIn, WhatsApp, Instagram, Gmail, Outlook, and IMAP into a single unified inbox. With Unipile, you can send and retrieve messages across channels, manage calendars (Google/Outlook), sync conversations in real time, and maintain full historical context across channels. The API supports functions such as starting chats, retrieving message threads, scheduling events, and connecting profile data, all through the same interface. Use-cases include ATS/CRM software publishers, outreach tools, no-code builders, and AI agent platforms, anywhere multi-channel communication needs to be embedded into an application.
