# The WhatsApp API for campaigns that land without getting numbers banned.

Your team needs to run campaigns at scale without watching numbers get banned at the peak. The D-API WhatsApp API delivers real isolation, a unique IP per connection and response reports so your operation grows safely.

-   Reports: In real time
-   Native CTAs: Buttons, lists, carousels
-   Isolation: 1:1 per number

Short answer

## How do you run WhatsApp campaigns with less risk of bans?

Spread the volume across several numbers, each in an isolated connection, instead of concentrating everything on one number. At D-API each connection has a dedicated proxy with its own IP, and the dashboard shows delivery, reads and replies per campaign. Bans depend on sending behavior, so relevant content and gradual volume remain the main protection.

The problem

## You shouldn't be solving this.

Problems D-API takes off your plate.

1.  ### Campaigns that never arrive
    
    Unstable infrastructure makes your campaign fail without you knowing.
    
2.  ### Numbers banned without warning
    
    A single number carrying everything means ban risk and a lost audience.
    
3.  ### No reporting
    
    Without delivery, read and reply data, your decisions are guesswork.
    

How it works

## From zero to production in four steps.

1.  ### Connect your numbers
    
    Add as many numbers as you want in the dashboard and the system provisions isolated instances.
    
2.  ### Build the campaign
    
    Use the API or an automation node (n8n, Make) to send messages at scale.
    
3.  ### Engage with native CTAs
    
    Add buttons, lists, carousels and payment links to increase conversion inside the chat.
    
4.  ### Track results
    
    See delivery, read and reply rates by campaign, instance or period.

FAQ

## Frequently asked questions.

### Can D-API get my number banned?

Bans depend on behavior (spam, volume, content). D-API is infrastructure: if you follow best practices, stability works in your favor.

### How many numbers can I connect?

Unlimited. On the Scale plan you only pay for the connections you use, and the unit price drops as the total grows.

### Can I get reports per campaign?

Yes. Filters by instance, period and message type let you analyze the performance of any campaign or flow.
