# Wink uses in-app nudges to guide merchants through integration setup and drive adoption of new payment methods

Digia Engage powers step-by-step merchant onboarding sequences, feature discovery bottom sheets, and fraud alert widgets inside the Wink dashboard.

## About Wink

Wink is a modular payments platform connecting identity, risk, and commerce in a single stack. The platform powers biometric checkout (face, palm, voice), payment orchestration across 200+ gateways, AI-powered fraud detection, and age verification.

- Biometric checkout: face, palm, and voice authentication
- Payment orchestration across 200+ gateways
- Integrated with Fiserv/Clover, SUNMI, PAX, and Qualcomm

## The Challenge

Wink's merchant onboarding is complex. Each integration partner (Clover, SUNMI, PAX) requires custom setup flows with different API configurations, compliance steps, and go-live checklists.

- Every onboarding variation required native development. The product team wanted step-by-step guidance inside the app.
- When Wink launched a new biometric checkout option, existing merchants did not discover it.
- White-label customisation requests went through the engineering queue, slowing merchant activation.

## The Solution

Wink integrated Digia Engage to run merchant-facing in-app experiences without touching the core payments SDK.

- Step-by-step onboarding nudge sequence: after sign-up, the app shows a progress widget covering Connect POS, Configure payment methods, Run a test transaction, and Go live.
- Feature discovery bottom sheets that surface new payment methods at the right moment.
- Fraud alert inline widgets in the merchant dashboard when unusual activity is detected.
- White-label configuration through in-app widgets where merchants adjust checkout branding instantly.

## Results

- Merchant onboarding completion improved — step-by-step in-app nudges replaced static documentation.
- New payment method adoption increased — contextual feature discovery surfaces options when merchants are most likely to act.
- Partner-specific onboarding managed from the dashboard — not the codebase.
- White-label customisation without engineering tickets — merchants adjust branding through in-app widgets.
