Inboxapp is the single entrypoint to manage all your socials, starting with X (Twitter), with LinkedIn coming Q3 2026 and WhatsApp, Telegram, iMessage and Instagram coming Q4 2026. The API reads and acts on your team’s conversations: send and receive direct messages, keep contact data in sync with your CRM, and react to events as they happen. 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
