 Zalo Personal uses an unofficial, reverse-engineered protocol (zca-js) that is **not endorsed by Zalo/VNG**. Your account could potentially be restricted or banned by Zalo. **Use at your own risk.** For an official integration, consider [Zalo Bot Platform](#zalo) instead.

+Please use a **separate, dedicated Zalo account** for the bot — do **not** use the same Zalo account that users will use to talk to your COCO agent. The connected account becomes the bot's identity, so it must be a different account from any user who will interact with it.
