  4. Enterprise features: more advanced models and dashboards
    Nordigen offers a list of Enterprise-level features including advanced scoring models and predictive features for data scientists as well as visual dashboards for credit risk specialists.

Step 1: get bank data with Truelayer

Truelayer provides an account aggregation service that includes acquiring consent from end-users, connecting to their bank account and acquiring the end-users account information. According to Truelayer’s API documentation, the output files from Truelayer are JSON that contain raw bank account data, i.e end-user’s transaction history.

Step 2: enrich bank data with Nordigen

Nordigen provides a set of products that can be used on top of default Truelayer data Nordigen API. To integrate with our API, you can follow our short integration guide or dive right in to our developer-friendly API documentation.

🚀 Good news — Nordigen supports the default Truelayer JSON format, which simplifies the API integration process for all Truelayer users.

Nordigen products that are typically used on top of Truelayer data include:

  • Transaction Categorisation- categorise transaction data with high accuracy
  • Income Insights- verify end-user’s income amount, source and stability
  • Loans Insights- verify active liabilities and recent loan repayments, based on the loan type
  • Risk Insights- identify high-risk end-user behaviours and credit risk-related data points
  • Simple Score- measure the credit risk level based on end-user’s transaction history
  • Marketing Insights- identify end-user’s interest in specific fields (e.g. brands, products, etc.), based on their spending behavior.

If you’re already using Truelayer, the integration with Nordigen is very straightforward:

  1. Get the raw data file from Truelayer via API,
  2. Send the raw data file to Nordigen via API ( following our simple API docs );
  3. Get the enriched data file from Nordigen via API in seconds.

The file processing on Nordigen side typically takes 5–15 seconds. Larger Truelayer files (with longer transaction history) can sometimes take more time to process.
