About D-API

# WhatsApp API infrastructure built to scale without losing control

D-API is a **B2B WhatsApp API** built in Brazil for companies, SaaS products and automation teams that need stability, isolation and predictability, not another fragile connection that drops at the first traffic spike.

Why we exist

## What we built

We started from a concrete problem: unofficial WhatsApp solutions tend to share infrastructure, charge per message and break in production without warning. You can’t build a serious product on top of that.

That’s why D-API delivers a **dedicated proxy per connection**, **per-instance isolation** and **continuous self-healing**, with reliable webhooks, an official SDK and interactive Swagger documentation. All with billing per active instance: **no per-message fees**.

How we work

## Our engineering principles

1.  ### Dedicated proxy per connection
    
    Every connection gets its own dedicated IP, reducing blocks and keeping the number’s reputation under your control.
    
2.  ### Per-instance isolation
    
    One instance per number, with no shared neighbors. What happens on one connection never affects the others.
    
3.  ### 24/7 self-healing
    
    The infrastructure recovers on its own from drops and reconnections, targeting 99.9% uptime with no manual work.
    
4.  ### Webhooks you can rely on
    
    Retries with exponential backoff, so you don’t lose events when your endpoint has a hiccup.
    
5.  ### Official SDK and integrations
    
    Official Node.js SDK, n8n community node, Datacrazy CRM, Amazon S3/MinIO and event streaming via RabbitMQ.
    
6.  ### Billing per active instance
    
    You pay per active connection, not per message volume. Predictable for teams that really scale.
    

Company

## Who we are

D-API is operated in Brazil under CNPJ 40.925.787/0001-17. We serve SaaS, automation and marketing companies that embed WhatsApp into their own product or operation. Support is available in English: reach our team on [WhatsApp](https://w.d-api.cloud/) or by email at [contato@d-api.cloud](mailto:contato@d-api.cloud).

## What the D-API WhatsApp API is

**D-API is a WhatsApp API** built for teams that need real stability in production. Instead of spinning up an unofficial instance on a VPS and hoping the number stays connected, you connect your numbers through our managed infrastructure and integrate through a **REST API documented in Swagger**, with an official Node.js SDK, webhooks with retries and exponential backoff, and a dedicated proxy with a unique IP per connection.

Every number runs on an isolated instance: a problem on one connection never takes down the others. On top of that you get **24/7 self-healing**, 20+ servers across 3 datacenters and **99.9% uptime**, the foundation a serious WhatsApp operation needs to scale from the first number to the thousandth.

## Official or unofficial WhatsApp API?

The official WhatsApp API (Meta Cloud API) charges per conversation and requires template approval, customer service windows and messaging limits. The **D-API WhatsApp API** is an unofficial alternative based on the direct WhatsApp connection: you talk to customers without templates, without a 24-hour window and **with no per-message fees**, paying only for active instances. It is the choice for teams that want predictable costs and the freedom to automate.

## Who D-API is for

-   **SaaS and products:** embed WhatsApp as a multi-tenant feature, with one isolated instance per customer and predictable billing.
-   **Automation agencies:** n8n, Make and Zapier flows that run 24/7 without stalling halfway, with an official n8n community node.
-   **Marketing and sales:** multiple isolated numbers, response-rate reports and native CTAs (buttons, lists, carousels and payment links).
