    3. Click Add custom connector.

    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    get_merch_catalogThe current Abyssfall merch catalog (owner-maintained). Call this BEFORE preorder_merch to learn the valid item names. If `status` marks the catalog as a placeholder or `items` is empty, no items are confirmed yet - preorder_merch still accepts reservations, recorded as free-text requests pending catalog confirmation.

    preorder_merchReserve Abyssfall merch (preorder reservation — NO payment is taken and no card is needed). Call get_merch_catalog first; if the catalog is empty or the requested item is not listed, the reservation is recorded as a free-text request pending catalog confirmation. Records the reservation; the studio emails when the item ships/charges become real. Only call with the user's explicit consent.
