wuapi FAQ
Do I need business verification or approved templates?+
No. You link an existing number via QR or pairing code and send over REST; templates and verification belong to WhatsApp’s official Cloud API.
Is there a free plan?+
Yes. The Free plan includes 1 number, 2,000 messages and 0.5 GB proxy traffic per month, with no credit card required.
Webhooks or Streams?+
Use webhooks when you have a public HTTPS endpoint; use Streams for desktop or script environments where a public URL isn’t available.
Can my customers connect their own numbers?+
Yes. You can create a project per customer and send a branded invitation link; a white-label add-on removes the wuapi branding.
What happens if a phone goes offline?+
The number stays linked; wuapi’s proxy layer keeps reconnecting automatically and resumes when the device is back online.
Do you charge per message?+
No. Messages are unlimited and never billed; you pay only per connected WhatsApp number.
