Transactions

The Transactions module is the operational heart of Datalex. Every payment event processed by your system flows through this module, where it is enriched with risk signals, evaluated by active workflows, and made available for manual review and investigation. Transactions Overview

The Transactions list view with risk scores, statuses, and filter controls.

Transaction Graph

The Transaction Graph provides a network visualisation of relationships between transactions, users, merchants, and devices. It helps analysts identify fraud rings, account takeovers, and merchant collusion by revealing structural patterns that are invisible in flat lists.

Network graph showing connections between transactions, cards, merchants, and devices.

Node types in the graph

Node type	Represents
User	The platform customer
Transaction	An individual payment event
Merchant	A merchant or business
Device	A unique device fingerprint
Card	A payment card

Transaction Analytics

The analytics section of Case Management provides aggregated dashboards over the transactions linked to a set of cases, including:

Transaction volume by time period (area or line chart)
Status distribution breakdown
Risk score distribution histogram
Geographic heat map of transaction origins

Analytics charts for the transaction volume and status breakdown.

Geographic Map

The Location Map aggregates transactions by country and renders them as sized markers on an interactive map. Each marker shows the transaction count, total amount, and highest risk level for that country.
