WhatsApp API for your company's internal operations

Your team wastes time chasing customers about payments, updating deliveries and forwarding announcements to the wrong group, while critical system alerts arrive too late. With D-API's WhatsApp API for business, you connect your internal systems and send every automatic WhatsApp notification straight from your ERP, n8n or monitoring.

  • Uptime: 99.9%
  • Events: With retries
  • Payments: Link in the chat
The problem

You shouldn't be solving this.

Problems D-API takes off your plate.

  1. Manual collections that choke cash flow

    Someone in finance spends the day copying invoices and sending reminders on WhatsApp by hand. The receivables process does not scale and late payers forget the due date.

  2. Deliveries without tracking and customers calling

    Logistics cannot announce delivery windows or confirm receipt automatically. Support turns into a "where is my order" call center.

  3. System alerts nobody sees in time

    A queue overflowed, an integration went down, payslips need to reach the field team, and the information depends on someone watching a dashboard or checking email.

How it works

From zero to production in four steps.

  1. Connect your systems

    Integrate your ERP, management and monitoring tools via REST API or the official Node.js SDK.

    Read the docs
  2. Split by department

    Create an isolated number for finance, logistics, HR and IT, each with a dedicated proxy and its own IP.

  3. Build your automations

    Set up payment reminder flows, delivery notices and system alerts in n8n, Make or Zapier, or react to events via webhook.

    See integrations
  4. Track and expand

    Use real-time delivery and reply reports to fine-tune each flow and roll it out to new departments.

FAQ

Frequently asked questions.

How does D-API help with collections and finance?
You build an automatic receivables flow using the WhatsApp API for payment reminders, with native CTAs such as buttons, lists and a payment link. The customer gets the due date reminder and pays right in the conversation, and you track delivery in real time.
Can I notify customers about deliveries automatically?
Yes. Logistics connects the management system via REST API or webhook and sends automatic WhatsApp notifications about tracking, delivery windows and receipt confirmation, without anyone typing messages by hand.
Can I separate each department's WhatsApp?
Yes. You use multiple isolated numbers, one per department such as finance, logistics, HR and IT, each with a dedicated proxy and its own IP, so operations do not mix.
How do I get system alerts on WhatsApp?
Your monitoring sends events to D-API by webhook or through the n8n, Make and Zapier integration, and the tech team gets alerts on WhatsApp via API right on their phones. Webhooks retry with exponential backoff to ensure delivery.
How is the platform billed?
Billing is per active instance, with no per-message fees. You also get dedicated onboarding in a WhatsApp group to set up your internal automations.
