BuyLive Companion

BuyLive Companion is a browser helper for BuyLive sellers. It removes the two manual steps that used to need a person during a live: getting a TikTok assistant account's session into BuyLive Live Printer, and printing order labels. WHAT IT DOES • Link an assistant session in one click — no copy/paste. It detects the TikTok account(s) signed in to this browser and sends the assistant's session to YOUR OWN BuyLive backend, so in-chat auto-reply is armed instantly. • Self-healing. TikTok constantly rotates its session tokens; whenever they change, the session is re-sent automatically, so a live that was replying keeps replying. If the account logs out, you get a notification. • Live status. A read-only dashboard from your BuyLive backend answers one question — will my replies reach the chat? — plus viewers, on-air state, and session age. • Thermal printing. Print ESC/POS order labels (REF, buyer, item, price, a QR of the order link and a Code128 barcode) straight to a USB/serial thermal printer, with no browser dialog. PRIVACY & SECURITY • The session is sent ONLY to your own BuyLive backend — never to any third party. • The raw session stays inside the extension's background worker; the popup only ever shows masked values. • Use a secondary TikTok account as the assistant. Logging it out invalidates the session. Requires a BuyLive account. Web Serial (Chrome/Edge/Brave) is needed for thermal printing.
