Speak your customer’s language
Translate received messages and polish your own reply for the target language. Previous translations are saved instead of regenerated.
Your business, in context
Describe your company once. Your assistant uses that context and recent messages when improving a reply.
Watch for what you need
Describe today’s request, select groups and set a duration. Keyword matching and spelling tolerance help narrow messages before AI evaluation.
You choose the groups, duration and notification destinations. The assistant does not silently message prospects for you.
03 / FOR DEVELOPERS
A conversation can start with code.
Send OTP codes, order updates and transactional notifications from your product. Use reusable templates and variables, choose the sending number and inspect delivery logs.
- Access tokens with company permissions
- Reusable templates and recipient audiences
- API, SDK and command-line workflows
curl -X POST \

}'Use the API from your server; never expose an access token in client code. Send messages only to recipients who have consented.
Before you connect.
Do I need a WhatsApp Business account?
No. You can link a regular WhatsApp account using linked devices, by QR code or a phone-number pairing code.
Is this the official WhatsApp Business API?
No. WhatsApp Santral uses an unofficial linked-device integration. It is not affiliated with or endorsed by Meta or WhatsApp. Account restrictions and connection changes remain possible; use it responsibly and follow WhatsApp’s terms.
Is the group assistant only for one industry?
No. Describe what matters to your business: sales requests, supplier opportunities, freelance work or field operations. You control the groups, matching preferences and duration.
Can I send OTP codes from my application?
Yes. Connect a number, create an access token with sending permission and call the send API, SDK or CLI. Your application remains responsible for generating, expiring and validating the verification code.
Will AI automatically send my replies?
AI helps prepare translations and drafts. You review and send them. Group matches can be delivered to notification destinations you explicitly configure; AI access and limits vary by plan.
