Connect Your Zalo OA Account

Zalo OA (Zalo Official Account) is a business account on Zalo that lets your company receive and send messages with customers.

Use Zalo OA when your customers commonly contact you through Zalo — for example clinics, schools, ecommerce shops, or local service businesses.

After connection, messages appear in Inbox. Staff and AI Assistant can reply from one workspace.

Before you start​

  • You can sign in to the Zalo account that manages the Zalo OA.
  • You know which Zalo OA your business wants to connect.
  • Your Zalo OA is ready for business messaging (some permissions may require a verified or upgraded OA).
  • You have permission to manage Channels in ScaleFlow.

If your business does not have a Zalo OA yet, see Create a Zalo OA account below.

  1. In ScaleFlow, open Channels.
  2. Select Zalo OA from the channel list.
  3. Check the Connected accounts area.
  4. If no account is connected yet, click Connect.
