Threads
Threads is a separate connection from Instagram — it has its own webhook infrastructure and a Threads-specific event envelope. You can publish text, images, and video, and reply to comments.

How data arrives
Threads has a dedicated webhook (/api/threads/webhook) with its own
{ app_id, topic, values } envelope. It handles:
publish/authorization.removed— drive schedule and account transitions.replies/mentions— routed into the inbox.
Signature verification uses the same HMAC-SHA256 approach as the Meta webhook, keyed with the Threads client secret. See Webhooks.
Connect notes
- Threads is a separate app/connection from Instagram, despite both being Meta properties.
