List conversations

Fetch conversations (DMs) from all connected messaging accounts in a single API call. Supports filtering by profile and platform. Results are aggregated and deduplicated. Supported platforms: Facebook, Instagram, Twitter/X, Bluesky, Reddit, Telegram.

Twitter/X limitation: X has replaced traditional DMs with encrypted "X Chat" for many accounts. Messages sent or received through encrypted X Chat are not accessible via X's API (the /2/dm_events endpoint only returns legacy unencrypted DMs). This means some Twitter/X conversations may show only outgoing messages or appear empty. This is an X platform limitation that affects all third-party applications. See X's docs on encrypted messaging for more details.

Instagram and Facebook pre-connect history: when one of these accounts is connected, Zernio replays the DM history the account already holds on Meta, so conversations that began before the account was connected appear here. Up to 500 conversations per account are replayed. The replay runs in the background and can finish after a listing you have already taken, and replayed conversations keep their original lastMessageAt, so they sort into date order rather than appearing at the top. If you mirror this endpoint into your own store, re-run the sweep rather than relying on a single pass at connect time. Replayed history emits no webhooks and is stored as already read, so it never affects unread counts. Threads that Meta refuses to serve are skipped, and an account whose Instagram "connected tools" message access is turned off is not replayed at all.
