WhatsApp API for cart and sales recovery

You lose revenue every day to abandoned carts, unpaid payment links and overdue invoices nobody follows up on. With the D-API WhatsApp API, each of these events triggers a WhatsApp message at the right moment, without relying on human agents.

  • Uptime: 99.9%
  • Payment: Link in the chat
  • Delivery: With retries
The problem

You shouldn't be solving this.

Problems D-API takes off your plate.

  1. Abandoned carts go cold before any contact

    Conversion is high in the first minutes, but without an automatic send the customer has already bought elsewhere by the time you notice.

  2. Unpaid payment links become lost sales

    The checkout link is still valid, but without an immediate reminder the customer forgets and the payment never happens.

  3. Overdue invoices and declined cards overload the team

    Resending invoices, renegotiating and involuntary subscription churn eat hours of human support on tasks that should be automatic.

How it works

From zero to production in four steps.

  1. Connect your sales event

    Point your store or payment gateway webhook to D-API and send messages via REST API for every abandoned cart, unpaid payment link or overdue invoice.

  2. Build the recovery flow

    Use n8n, Make or Zapier to design the sequence of WhatsApp payment reminders, overdue invoice follow-ups and downsells, with your own timing and conditions.

  3. Turn on CTAs and payment links

    Resend the active payment link, offer a new invoice and renegotiation paths with native WhatsApp buttons, lists and carousels.

  4. Distribute and measure

    Route recovered leads to sales reps via the Datacrazy CRM integration and track delivery, reads and replies in real time.

What you get

React within seconds to the event that makes a customer give up.

  • Reaction within seconds

    Immediate send via REST API the moment the cart is abandoned or the payment link is created, while the chance of conversion is still high.

  • Webhooks with automatic retries

    Events arrive with exponential backoff retries, so no sales recovery is lost to a network failure.

  • Payment link right in the conversation

    Resend the active payment link inside WhatsApp in a native button, and use buttons, lists and carousels so the customer pays in one tap.

  • No-code recovery flows

    Build cart, overdue invoice and downsell flows with n8n, Make or Zapier, without waiting on an engineering deploy.

  • Multichannel coverage

    WhatsApp as the main channel, with SMS and IVR/voice as recovery layers for whoever did not reply to the first message.

  • Volume without bans

    Multiple isolated numbers and a dedicated proxy with its own IP per connection reduce the risk of blocks in recovery campaigns at scale.

  • Real-time metrics

    Live delivery, read and reply reports so you know which flow actually recovers sales and can adjust on the spot.

FAQ

Frequently asked questions.

How does abandoned cart recovery on WhatsApp work?
Your store sends an event to D-API as soon as the cart is abandoned and the API sends a WhatsApp message within seconds, still inside the window where conversion is high. You can include buttons and the active payment link so the customer completes the purchase without leaving the conversation.
Can I send payment reminders on WhatsApp automatically?
Yes. When a payment link is created and not paid, D-API resends the same active link inside the conversation in a native WhatsApp button. The whole flow is built via API or with tools such as n8n, Make and Zapier, with no human agents.
Can I automate overdue invoice follow-ups on WhatsApp?
Yes. You set up a flow that resends the invoice and offers renegotiation paths with native buttons and lists, all triggered by the due date event. This takes repetitive collections off your support team.
How do I recover churn from declined cards on subscriptions?
On each failed recurring charge, your gateway sends a webhook and D-API sends a message asking the customer to update their payment method, with a payment link as an alternative. That way you recover involuntary churn before the subscription is canceled.
Does sending recovery messages in volume increase the risk of bans?
D-API offers multiple isolated numbers and a dedicated proxy with its own IP per connection, which reduces the risk of blocks in recovery campaigns at scale. The platform runs with 24/7 self-healing and 99.9% uptime to keep sends active.
