Stripe checkout events trigger WhatsApp flows. Confirmations, dunning, subscriptions.
Quick check for decision makers
Turn payment events into WhatsApp flows.
After successful payment: automatic WhatsApp confirmation.
Stripe webhooks (payment_intent.succeeded, payment_intent.payment_failed, customer.subscription.*) auto-trigger Chatarmin flows. You configure once which event triggers which WhatsApp flow. After that, everything runs without manual intervention.
Payment failed? WhatsApp reminder instead of email.
Failed payment triggers a WhatsApp reminder with a link to update payment. Response rates for WhatsApp dunning are significantly higher than email dunning. Especially effective in combination: email AND WhatsApp in parallel.
Renewal, cancellation, upgrade. All as WhatsApp triggers.
Every Stripe subscription event can trigger a specific WhatsApp flow. Renewal, cancellation, downgrade, upgrade. When cancellation intent is detected, a retention flow starts automatically via WhatsApp. You accompany the entire subscription lifecycle.
Stripe is the most widely used payment infrastructure in e-commerce and SaaS. The Chatarmin integration uses Stripe webhooks to turn payment events into WhatsApp triggers. Payment confirmation after checkout, reminders for failed payments, subscription events. All automated via WhatsApp instead of email.
The connection runs via Stripe webhooks or middleware like Make.com/Zapier. Stripe events like payment_intent.succeeded, payment_intent.payment_failed, or customer.subscription.* automatically trigger Chatarmin flows. You configure once which event triggers which WhatsApp flow. After that, everything runs automatically.
Why WhatsApp instead of email for payment events? 85% open rate on WhatsApp vs. 20-30% for email. For time-critical messages like failed payments, this difference is the difference between recovered and lost revenue.
Three categories of Stripe events can be used directly as WhatsApp triggers:
Especially effective is the combination: failed payment via email AND WhatsApp. Those who ignore the email get the WhatsApp message. Dunning recovery rates increase measurably.
The Stripe WhatsApp integration is built for shops and SaaS companies that use Stripe as their payment provider and want to automate transactional WhatsApp messages.
Typical profiles:
After successful checkout: automatic WhatsApp message with order details.
Credit card expired? WhatsApp reminder instead of email. Higher response rate.
Renewal, cancellation, or downgrade trigger WhatsApp flows.
The integration is webhook-based and works from the moment you configure the events. No complex setup, no lengthy implementation.
The first scenario: payment confirmation via WhatsApp. After successful checkout, the customer automatically receives a WhatsApp message with order details. Faster and more visible than email.
The second: failed payments via WhatsApp. Credit card expired? Chatarmin sends a WhatsApp reminder with a link to update payment. Higher response rate than email dunning.
The third: automate subscription events. Renewal, cancellation, or downgrade trigger WhatsApp flows. When cancellation intent is detected,

Stripe sends automatic email notifications for payment events. Stripe does not offer WhatsApp notifications. Chatarmin adds exactly this functionality: WhatsApp notifications for every Stripe event, automated dunning flows via WhatsApp, personalized messages, and GDPR-compliant servers in Germany.
The combination of Stripe email and Chatarmin WhatsApp maximizes reachability for time-critical payment events.

Payment events trigger WhatsApp flows automatically.
11 cents per message sounds expensive. 11 cents is the official Meta fee for marketing messages in Germany, while Austria and Switzerland pay roughly 5 cents (as of 2026). For transactional messages (payment confirmations, dunning), costs are even lower since service messages within the 24-hour window are charged at a reduced rate.
Chatarmin has two cost components: the software license (monthly fee) and Meta fees per message. Chatarmin passes these costs through 1:1 with no markup.
The ROI for dunning messages is directly measurable: every recovered payment is real money. With an average order value of 80 EUR, the 11 cents per message pay for themselves with the first recovered transaction.
