API v1 is deprecated. It stops responding on 3 December, 2026. Build with API v2, and move an existing integration with the migration guide.

​
Current support

API v1 supports X (Twitter) DMs. All API endpoints, webhooks, and features documented here work with X. LinkedIn and WhatsApp are available through API v2.

​
Platform roadmap

New platforms are available through API v2 only.
API v1 is frozen, so it won’t gain new platforms. To reach LinkedIn or WhatsApp, move to API v2.

​
What “platform-agnostic” means for your code

The data model uses generic concepts that map across platforms: To use a new platform, move your integration to API v2, which is one API for every platform Inboxapp supports. See Platforms for what each one can do.
