Transaction Categorisation

Operation keyword: categorisation

Transaction Categorisation is a pre-trained solution that processes an end-user's (a person) account information and identifies the type and purpose of a transaction, based on its description, transaction amount, date, and contextual metadata. The solution is trained on millions of data points using advanced algorithms and it's constantly improved to recognise new merchants, payment types and consumer trends. Based on the country, the product categorises incoming and outgoing transactions into 120+ categories with high accuracy.
The solution can be used to process personal or depersonalised account information from a variety of transaction sources, including open banking data, debit and credit card transactions and user-provided bank statements.
To see the latest category tree (i.e. full category list) available in your country, you will need to create a free account on our Dashboard and follow the instructions in the Endpoints section to retrieve the latest category list.
