Supported platforms - Inbox API

Current support

The Inbox API currently supports X (Twitter) DMs. All API endpoints, webhooks, and features documented here work with X.

Platform roadmap

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.

What “platform-agnostic” means for your code

The data model uses generic concepts that map across platforms:

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
Account link	Connected X account	Connected IG account	Connected LI account

Code you write today against the X integration will require minimal changes when new platforms are available. The main difference will be the platform field value on API objects.
