# Overview

> The API for sending and managing DM conversations across X, Instagram, LinkedIn, and more

## What is Inbox?

Inbox is the API for sending and managing DM conversations across messaging platforms — starting with X (Twitter), with Instagram and LinkedIn coming Q2 2026.

Send and receive DMs through a unified API, sync conversations with your systems, and build custom workflows. Your team also gets a fast inbox interface to manage conversations, assign threads, and collaborate in real time.

<Info>
  **Platform support**: The API currently supports X (Twitter) DMs. Instagram
  and LinkedIn are coming in Q2 2026. See [Supported platforms](/resources/supported-platforms)
  for the full roadmap.

**For teams:**

* Manage all X DM conversations in one place
* Assign, tag, and track conversations
* Organize with tags and workflow stages
* Real-time collaboration

**For developers:**

* Programmatic access to all conversations
* Reliable message delivery
* Sync data with external systems
* Build custom integrations
