How to Send WhatsApp Messages Using WaSMS.net API (Free + No App Required)

If you're a developer or business looking to send WhatsApp messages without being locked into Meta’s official API, this guide is for you. With WaSMS.net, you can use your own WhatsApp account and send messages directly using a secure API — without installing any apps!

No App Required – Just Your Browser

Unlike SMS (which requires the Android gateway app), WaSMS.net’s WhatsApp solution works entirely online. All you need to do is register and scan a QR code to connect your account — just like WhatsApp Web.

How to Set Up Your WhatsApp API Gateway

1. Visit https://sys.wasms.net and create your free account (lifetime free plan)
2. Login, go to Hosts → WhatsApp, and click Add Account
3. Select a WhatsApp server and scan the QR code using the WhatsApp account you want to connect
4. Your account will now be linked and ready to use via dashboard or API

Generate Your API Key

Navigate to Tools → API Keys and click “Add Key.”

• get_wa_accounts – Access your connected WhatsApp accounts
• get_wa_sent – View sent messages
