After implementing your first payment, you must verify that your integration works reliably across the full payment lifecycle.
What to Verify
A successful integration is more than just a successful payment—it must handle all key scenarios.
1. Successful Payments
Confirm that:
The payment completes successfully
The frontend receives a success response
The user experience is correct
2. Webhook Handling (Critical)
Adyen sends webhooks with the final payment status.
Verify that:
Your webhook endpoint is reachable
You receive events such as
AUTHORISATIONYour system updates payment status correctly
Without webhooks, your integration is incomplete.
3. Failure Scenarios
Test common failure cases:
Refused payments
Invalid card details
Cancelled payments
Ensure your system:
Handles errors gracefully
Displays appropriate messages
4. 3D Secure / Additional Actions
Some payments require extra steps.
Verify that:
Redirects or challenges work correctly
The user returns to your application
The payment completes after authentication
5. Environment Configuration
Double-check:
You are using test credentials
You are calling test endpoints
No live configuration is mixed in
6. Store ID and Configuration
Ensure:
Store ID is always included
Merchant account is correct
Payment methods appear as expected
7. Logs and Debugging
Review:
Backend logs (API calls, errors)
Frontend logs (Drop-in events)
Webhook payloads
This helps identify hidden issues early.
Before Going Live
Before moving to production, confirm:
✅ End-to-end flow works
✅ Webhooks are processed correctly
✅ Error handling is implemented
✅ No test-only configurations remain
Key Takeaway
A working payment is not enough—your integration must correctly handle success, failure, and asynchronous updates before going live.
