WhatsApp for software platforms
Send WhatsApp messages from your own product by API, get every reply and delivery update by webhook, and let each of your customers connect their own number without leaving your app.
What you can send
Every message comes from your own WhatsApp number, and replies land in your Sonar inbox. A few examples:
How Sonar helps
- Templates and messages by API. Send approved templates with buttons and variables, or free-form replies inside the 24-hour window. A reference on each send stops the same message going twice. Developers: API and webhooks
- Webhooks for everything. Incoming messages, button taps, and delivery and read updates, signed and retried for about 2 days, with a delivery log.
- Each customer connects their own number. With the partner API, each of your customers runs Meta's sign-up from inside your product and gets their own business in Sonar, with their own contacts and opt-outs. Their number stays in their own Meta business portfolio.
- Contacts kept in step. Add and update contacts, tags and opt-ins from your system, and Sonar applies the same consent rules to every send. How it works
- An inbox when people reply. Replies land in Sonar's shared inbox too, so your team or your customer's team can answer without you building one.
- Official and approved. Sonar is a Meta Tech Provider on the official WhatsApp Business Platform, and sends through Meta's Cloud API.
What it costs

Questions
Is the API on every plan?
Yes. The API and webhooks come with every plan, month to month, with no setup fee. The developer guide and the full API reference show every call.
We have many customers, each with their own number. How is that priced?
Each customer you connect through the partner API becomes its own business in Sonar, on its own plan. Email support@whats-hub.co.za about partner pricing for many customers.
Can we test before going live?
Yes. Start a free trial with a test number and send your first templates, then add your live number on a paid plan.
