go-notification

Wablas is another popular Indonesian WhatsApp gateway. Similar category to Fonnte — cheap, fast to set up, unofficial.

Unofficial API

Wablas uses the unofficial WhatsApp Web protocol. Against WhatsApp's Terms of Service — number ban is a real risk. Suitable for low-volume ops, internal notifications, MVPs. Not recommended for mission-critical customer comms.

Pricing

Trial — free with limited quota.
Paid — from around Rp 50,000 / month (≈ $3 USD), scaling up with device count and message volume.
Check https://wablas.com/pricing for current tiers.

Setup

Register at https://wablas.com.
Add a device and scan the QR code with your WhatsApp phone.
Copy the device token from the Wablas dashboard.

Operational tips

Same ban-risk mitigations as Fonnte: rate-limit yourself, honor opt-outs, don't blast cold contacts.
Register two providers (e.g. Fonnte as whatsapp-a, Wablas as whatsapp-b) and switch in code if one number gets flagged — keep a spare warm.
