Current support
The Inbox API currently supports X (Twitter) DMs. All API endpoints, webhooks, and features documented here work with X.
| Platform | Status | Expected |
|---|
| X (Twitter) | Available | — |
| Instagram | Coming soon | Q2 2026 |
| LinkedIn | Coming soon | Q2 2026 |
| TikTok | Planned | TBD |
| WhatsApp | Planned | TBD |
The API is designed to be platform-agnostic. When new platforms launch, your existing integration patterns (threads, messages, prospects) will work the same way — the platform field on objects will reflect the new platform.
| Inbox concept | X (Twitter) | Instagram | LinkedIn |
|---|
| Thread | DM conversation | DM conversation | Message thread |
| Message | Direct message | Direct message | InMail / message |
| Prospect | X user | Instagram user | LinkedIn user |
