Step 1: get bank data with Plaid

Plaid 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 Plaid’s API documentation, the output file from Plaid is JSON that contains 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 Plaid 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.

The Nordigen products that can be used on top of Plaid 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

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

  1. Get the raw data file from Plaid 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.
