Introduction to Financial Data


The Financial Data Product empowers you to perform granular operations on bank account data with precision and efficiency. By granting access to end-users' financial accounts, it opens the door to a comprehensive array of financial capabilities. This product enables the retrieval of detailed account information, such as account numbers, balances, and transaction histories, and equips your applications with real-time transaction data for a myriad of use cases. It ensures user consent management, adheres to stringent compliance and security standards, and is designed to facilitate the creation of personal finance tools, budgeting applications, lending and credit scoring systems, expense trackers, account aggregators, and real-time fraud detection mechanisms. Our Financial Data Product equips your applications with the technical foundation to redefine how financial data is harnessed and leveraged.

Data-Access Types

Onetime Account Access

The one-time account access is normally used by customers who want to verify or access certain information only once at one point in time.

In case of a one-time account account access, Qwist will store the financial data of an end user for 1 hour. During this time the customer can fetch the financial data from Qwist’s database as often as needed. After 1 hour Qwist will delete the financial data of the end user from its database.


API Access & Authentication

The finX API is a restful API that is accessed using HTTP Basic Authentication with a Client ID as username and a Client Secret as password. Therefore each customer receives a Client ID and Client Secret from Qwist to access the finX API, which has a specific set of Scopes attached to it. Scopes define the usage rights of each Client ID on the finX platform.
