Banking API — BNPL
Bank Data-Driven Credit Decisioning for BNPL Providers
Go beyond credit bureau scores with CDR bank data analysis for BNPL credit decisions. Fiskil's API provides cash flow-based credit assessment that approves more good customers and catches more bad ones.
Traditional credit bureau scores were designed for traditional credit products — they tell you what happened in the past, not what is happening now. For BNPL providers, where transaction values are lower and decision speed is critical, real-time cash flow analysis from CDR bank data provides a fundamentally better signal for credit decisions. Fiskil analyses actual income patterns, spending behaviour, and financial stability to enable smarter credit assessment that approves more creditworthy consumers while reducing default risk.
The Challenge
Traditional credit scores miss the real-time financial context that determines whether a consumer can afford a BNPL purchase today.
The Solution
Fiskil analyses CDR bank transaction data to build a real-time credit profile based on actual cash flow, income stability, spending patterns, and financial behaviour — not just historical credit events.
Capabilities
How Fiskil Helps
Cash Flow Scoring
Generate a cash flow score based on income regularity, surplus cash after commitments, savings behaviour, and account balance trends — signals that predict BNPL repayment better than credit scores.
Income Pattern Analysis
Identify income sources, regularity, and trends. Detect recent changes like job transitions or income drops that credit bureaus take months to reflect.
Financial Stress Detection
Identify early warning signs of financial stress including declining balances, increasing overdraft usage, dishonoured payments, and growing BNPL stacking across providers.
Thin-File Customer Assessment
Assess creditworthiness for consumers with limited credit history by analysing their banking behaviour — income deposits, bill payment patterns, and savings consistency.
Implementation
How It Works
Customer Connects Banking
At registration or first purchase, the customer connects their primary bank account via CDR consent. The process takes under 2 minutes.
Build Cash Flow Profile
Fiskil analyses 3-6 months of transaction history to generate a cash flow profile covering income, expenses, commitments, and behavioural indicators.
Generate Credit Assessment
The API returns a structured credit assessment including cash flow score, risk flags, recommended spending limit, and supporting data points for your decisioning engine.
Integrate with Decisioning
Feed the CDR credit assessment into your existing decisioning rules alongside (or instead of) traditional credit bureau data to make smarter approve/decline/limit decisions.
In Practice
How Teams Use This
BNPL Provider Expanding to Thin-File Segments
A BNPL provider wanted to serve international students and young adults who were consistently declined by credit-score-based models despite having regular income.
CDR cash flow assessment enabled approval of 34% of previously declined thin-file applicants with a default rate of only 2.1% — below the portfolio average of 2.8%.
Reducing Defaults Through Stress Detection
A BNPL platform layered CDR financial stress indicators onto their existing credit bureau assessment to catch consumers in early-stage financial difficulty.
Default rate reduced from 4.2% to 2.7% by declining or reducing limits for consumers showing declining balances and increasing overdraft usage, despite passing credit score thresholds.
BNPL Stacking Prevention
A provider detected that 18% of their defaulting customers had undisclosed BNPL commitments with three or more other providers, invisible to credit bureau data.
Implementing BNPL stacking detection from CDR data reduced multi-provider defaults by 52% and improved overall portfolio quality.
