co·ex·ist·ence noun · the way we operate
The official WhatsApp Business app and the API, live at the same time on the same number. No migration. No switching off the app.
product
Cero Manual WhatsApp is a thin API plus an onboarding service. We fight the platform; you write your product.
scope: customer-service conversations, inside the 24-hour window, via coexistence
Serve your customers on WhatsApp Business without migrating the number: coexistence keeps the app running while your software replies through the API.
Onboarding covers the coexistence of your number. Meta business verification is Meta's own process and is out of our scope.
// this is coexistence: both channels live at once
always yours
Cero Manual runs the infrastructure. The relationship with your customers — and everything that holds it up — stays yours.
your Meta business assets
your phone number
your WhatsApp conversations
your data and your customers' data
how it works
Three stages with a clear boundary: we fight the platform, you write your product.
01 connect
Coexistence onboarding and ready-to-use credentials. We stay with you until the connection is live.
02 integrate
Add messaging to your product with a REST API and webhooks. Documentation is shared during the beta.
03 operate
Connection monitoring, 24-hour window tracking and ongoing technical support in English and Spanish.
who it's for
Run WhatsApp for several clients without carrying each number's infrastructure.
Add WhatsApp support to your product as one more feature, not a separate project.
Build platforms for your clients on a base that already solved the hard part.
Integrate on your own, with technical guidance in English or Spanish when you need it.
primary model
The experience carries your client's brand; the infrastructure runs on us. You bill your client — we are your provider.
Need us to implement it for you? Managed mode: we set up and operate the product for your business, with a setup fee plus a monthly fee.

We'd rather tell you the real status of each piece than link you to empty pages.
