Case Study: Lazada Group achieves 243% ROI and 90% fraud detection precision preventing promo abuse with Ekata's Transaction Risk API

Preventing promo abuse during peak sales periods at Lazada

Lazada Group, a leading Southeast Asian ecommerce marketplace, faced rising promotion abuse—customers exploiting vouchers during frequent flash sales—which threatened marketing budgets and customer experience. Compounding the problem were poor data inputs (missing or misformatted addresses, mixed-up name/phone fields), so Lazada Group turned to Ekata and its Transaction Risk API (TRAPI) to tighten checks at the point of checkout.

Ekata’s TRAPI was integrated into Lazada Group’s pre- and post-authorization workflows to score transactions in real time and remove high-risk vouchers before payment, using top signals like Phone Carrier, Email First Seen Days, and IP Connection Type. The Ekata solution delivered a 243% ROI on voucher fraud use cases and detected fraud with over 90% precision, protecting marketing spend while improving overall transaction approval quality.
