Talk to your customers on WhatsApp the official way: connect your business number through Meta’s Cloud API, reply to customers, send approved template messages and connect WhatsApp to your CRM, website or ERP.
Synex WhatsApp connects your WhatsApp Business number through Meta’s Cloud API in a few clicks. You sign in with your own Facebook login — we never ask for your password — and Meta verifies the number with a code.
Reply to customers
Receive customer messages and reply free of Meta charges within 24 hours of their last message.
Approved template messages
Start conversations with message templates approved by Meta — order updates, reminders and offers — sent only to customers who opted in. Unsolicited messages are not allowed, so your number stays in good standing.
Several numbers, one dashboard
Connect more than one business number and manage them together.
Connect your systems
Send messages from your own software with the Synex REST API, and receive incoming messages and delivery updates on your webhook — ready for your CRM, website or Synex POS and ERP.
How to start
- Choose a plan — we create your account and send your login.
- Connect with Facebook — pick your business and WhatsApp number and approve access.
- Start messaging — reply, send approved templates, or use the API and webhooks.
A number on the official platform needs a Meta Business account. Meta charges some conversations (mainly template messages) directly to your WhatsApp Business account. Get started at wa.synex.work.

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.
