Bulk messaging with the official WhatsApp API, SMS and IVR
Betting on a single channel leaves half of your audience without the message. With D-API you send in bulk through the official WhatsApp API (Meta Cloud API) with approved templates and still reach whoever did not reply by SMS and IVR.
- Channels: WhatsApp, SMS, IVR
- WhatsApp: Official API
- Uptime: 99.9%
You shouldn't be solving this.
Problems D-API takes off your plate.
A single channel leaves people out
Not every contact opens or replies on WhatsApp. Without SMS and IVR as backup, you simply do not reach a large part of the audience you need to reach.
Without an official channel, the campaign is limited
Notices and campaigns at scale call for a verified channel with approved templates. Without the official API, you have no predictability or backing for volume.
Each channel with a different vendor
WhatsApp in one place, SMS in another, IVR in another. Separate integrations, scattered reports and no single view of the flow.
From zero to production in five steps.
Talk to sales and pick the channels
We map your flow and define which channels come in: the official WhatsApp API for verified sends, SMS and IVR for recovery.
Activate the official API and templates
We set up your official channel (Meta Cloud API) and the approved templates the campaign needs to send at scale.
Integrate in minutes
Connect via documented REST, the official Node.js SDK or the official n8n node and start sending.
Read the docsSend and track
Run your campaigns and track delivery, reads and replies in real time on each channel.
Recover whoever did not reply
Turn on SMS and IVR as backup layers to automatically reach contacts who did not engage on WhatsApp.

Multichannel bulk messaging: official WhatsApp, SMS and IVR in a single flow.
Official WhatsApp API provider
D-API acts as an official API provider (Meta Cloud API), sending through approved templates, so you run bulk messaging on a verified channel.
Bulk SMS
SMS arrives even without an app installed, with universal reach. Use it as the backup layer of the flow so no contact goes without the message.
IVR for collections and voice
Automate collections, confirmations and surveys by phone. IVR reaches people who do not open messages and closes the loop on the campaign.
Combined multichannel strategy
Official WhatsApp as the main channel, SMS and IVR as recovery layers for whoever did not reply. All orchestrated in one place.
Programmable sending via API
Run campaigns via documented REST, the official Node.js SDK or the official n8n node, with Make, Zapier and Datacrazy CRM integrated.
Real-time reports
Track delivery, reads and replies live on each channel to act before a problem becomes a loss.
