TrueLayer enriches transactions with 2 fields that aren't returned by most bank PSD2 APIs:
transaction_classification
We analyse transaction data to produce a predicted classification. This feature is supported for purchase and direct debit transactions.
This field is an array with two elements: primary-classification and sub-classification. E.g.:
"classification": ["Shopping", "Groceries"]
merchant_name
We analyse the transaction description in an attempt to extract the merchant name. This feature is supported for purchase and direct debit transactions.
This field is a string Eg:
"merchant_name": "Deliveroo"
