What is Inbox?

Inbox is a sales-focused DM management platform, starting with X (Twitter). Your team manages all conversations from a single, fast interface — assign threads, tag prospects, and track your pipeline. The Inbox API gives developers programmatic access to these conversations. Automate your outreach, sync with your CRM, build AI-powered responses — while your team keeps the human touch through the Inbox interface.
Platform support: The API currently supports X (Twitter) DMs. Additional platforms including Instagram are on the roadmap.
For teams:
  • Manage all X DM conversations in one place
  • Assign, tag, and track conversations
  • Pipeline stages for sales workflows
  • Real-time collaboration
For developers:
  • Programmatic access to all conversations
  • Send messages at scale
  • Sync data with external systems
  • Build custom integrations
