Send invoices, receipts, order updates and payment reminders on WhatsApp from your verified business number on the official WhatsApp Cloud API, alongside Synex SMS from your own gateway.
Connect your verified business number on the official WhatsApp Cloud API with your API key in settings — green-tick ready, with Meta-approved message templates and no ban risk. Then choose which messages go out on their own — a sale, a receipt, a quotation, a web order update or an overdue reminder — and word each one your way.
Messages always come from your verified business number. Every message is logged, including why one wasn't sent, practice documents are never sent, and you can send any document by hand in one tap.

Questions
Is Synex WhatsApp an official WhatsApp solution?
Yes. It is built on Meta’s WhatsApp Business Platform (Cloud API). You connect your number with your own Facebook login and Meta verifies it with a code.
Can I send bulk promotions on WhatsApp?
Only with Meta-approved templates, and only to people who agreed to receive messages from you. Unsolicited messages are not allowed.
Can I keep using WhatsApp on my phone?
Depending on how the number is set up, the WhatsApp Business app and the official platform can be used together (Meta “coexistence”), or the number moves fully to the platform. We guide you during setup.
What does Synex WhatsApp cost?
Plans start at LKR 10,000 per 30 days for one number (Business: 3 numbers for LKR 25,000; Agency: 5 numbers for LKR 35,000). Plans do not auto-renew. Meta conversation charges are separate and billed by Meta.
