Overseas customers on WhatsApp, answered by the whole team
Overseas customers often use only WhatsApp. hOne links a staff WhatsApp number as a companion device so messages sit in the shared inbox, with limits that help keep the number safe.
The problem
International customers message one person phone
Partners and overseas customers are used to WhatsApp. They write to one staff number, so when that person is away nobody knows what the customer asked, and the history is not in the company system.
- WhatsApp messages stay on a personal phone and cannot be tied to a customer record.
- Colleagues cannot see the conversation to reply or take over.
- Sending many new chats to strangers quickly can get a number banned by WhatsApp.
How hOne solves it
Linked like WhatsApp Web, with safety guards
You scan a QR in hOne just like linking WhatsApp Web. Messages appear in Chat with your other channels. hOne sends one message at a time, spaced like a person typing, caps new conversations per day, and never lets AI message first.
Key capabilities
Controlled new chats
To message a number you never contacted, click "Start chat" and enter an international number (for example +84912345678). New numbers have a daily allowance; customers who write back are not limited.
Sending limits that protect your number
By default 20 new conversations per day, 1.5 to 4 seconds between messages, a "typing" indicator and at most 20 messages per minute. Admins adjust this under "Sending limits".
Reply, react, edit, recall
Quoted replies, reactions, files and voice messages. Edit within the first 15 minutes and recall within 48 hours, as WhatsApp itself allows.
AI replies only, never first
AI replies only within a period after a customer message (24 hours by default) and never opens a new conversation. Staff can switch AI off per conversation.
Monitor and unlink
The channel shows its connection status, with a "Relink" button. Session data is encrypted. "Unlink" removes the hOne device from the phone; older messages stay in hOne.
How it works
Ask for WhatsApp to be enabled
Personal WhatsApp is enabled on request for your company account. If you do not see the WhatsApp button under Channel accounts, contact hOne.
Link the phone number
Click the WhatsApp button, fill in the details, choose how much history to import, then scan the QR in WhatsApp under Linked devices. Once it says "Linked" you can use it.
Chat with customers
When a customer writes, the conversation appears in Chat. To message a new number first, use "Start chat" within the daily allowance.
Keep the number healthy
Use it for 1-to-1 conversations, not ads or bursts of messages. Bring the main phone online from time to time.

Frequently asked questions
Is this the official WhatsApp Business API?
No. hOne links your number as a companion device like WhatsApp Web (personal WhatsApp or the WhatsApp Business App). That is why it is meant for 1-to-1 conversations with customers, with spacing and daily allowances that keep your number safe.
Can I send bulk or marketing messages?
hOne uses WhatsApp for 1-to-1 conversations: each send is one message to one conversation, spaced out and capped per day. For bulk sending, use Zalo Broadcast or Email Marketing.
Does AI ever message customers first?
Never. AI replies only within a period after the customer message (24 hours by default). Messaging a new number first happens only when staff click "Start chat".
What if the phone is off or offline?
The channel works as a companion device, so the main phone must come online from time to time. After about 14 offline days WhatsApp unlinks it; hOne notifies the channel owner, you relink, and the history in hOne is kept.
What about WhatsApp groups?
Group chats appear like normal conversations so you can talk as usual. Creating groups and adding members is done in the WhatsApp app itself.
How is personal WhatsApp different from WhatsApp Business?
hOne links an employee's personal WhatsApp number with a QR code, like adding a linked device. You reply to customers inside the shared inbox and the history stays on the customer record.
