Inspiration
Payment disputes and chargebacks take days of manual review to settle, frustrating both buyers and merchants. We built ResolvePay to automate dispute evaluation and execute instant, fair settlements using AI and PayPal.
What it does
- Automated Intake: Collects transaction details and dispute evidence in one streamlined interface.
- AI Evidence Analysis: Evaluates receipts, claim context, and fulfillment proof in seconds to generate a transparent, unbiased decision.
- Instant PayPal Settlement: Automatically executes approved refunds or payouts via PayPal APIs.
How we built it
We built a React (Vite) frontend connected to a Java & Spring Boot 3 REST backend and PostgreSQL database. The Gemini API powers structured evidence evaluation, while PayPal APIs handle transaction verification and automated settlement.
Challenges we ran into
Structuring unpredictable, free-text user dispute claims into reliable AI outputs and keeping transaction states synchronized with PayPal so duplicate refunds never occur.
What we learned
Designing idempotent payment state machines, enforcing structured AI reasoning schemas, and integrating end-to-end PayPal APIs under a tight deadline.
