A WhatsApp API that stays out of your way
Send templates, messages and campaigns from your own software. Every reply, tick and STOP comes back as a signed webhook.

Send a message in one call
Send a template, a text inside the 24-hour window, a file, or tap buttons and lists. The same Idempotency-Key never sends twice.

Partner API: your users’ own numbers
Platforms can connect their own users’ WhatsApp numbers without those users making a Qubox login. We run our own platforms this way.
