st.syncInbox

This action enables whole-inbox monitoring for your account so you can poll the inbox for messages across every conversation.

Unlike st.syncConversation, which watches a single person's conversation, st.syncInbox starts tracking all incoming threads in your inbox. Run it once per account. After it succeeds, new messages become available through the inbox polling endpoint — no need to sync each conversation individually.

💡 Only messages that arrive after inbox sync is enabled are captured. History predating the moment you enable it is not imported.

This action only switches monitoring on: it records the setting and returns. It does not browse your inbox and does not open anyone's profile. The messages themselves are picked up afterwards by a sync that runs periodically, so the first ones appear on the next sync rather than the moment the action completes.

Note: When that sync finds new messages in a thread – including messages you send yourself – it opens the profile page of the other participant in that thread to resolve their public URL – but only when Linked API does not already know it, so a person is visited once, which is what fills personPublicUrl on the messages you poll or receive by webhook. Those visits are made from your own account, and such a visit is visible to the person whose profile is opened.
