- Automatic notifications — order confirmations, payment links and reminders, delivery updates and appointment alerts.

WhatsApp Business app vs Business API
The WhatsApp Business app works on a single phone for small teams. The Business API is built for growing businesses: many agents on one number, automation, chatbots and integration with your software. If your team shares one phone or misses messages, it is time for the API.
Secure and compliant
We follow WhatsApp's messaging and opt-in policies, use approved templates and handle data under ISO 27001:2022-certified practices.
How we work
Most integrations go live in 1–2 weeks. A named manager owns your project, and a written SLA covers monitoring, changes and support afterwards.
