How get started with the US Open Banking APIs

First, I should quickly explain what I mean by Open Banking. Simply put, it allows the owner of a bank account to grant third-party access to that bank account. They can control what accounts can be seen, how long that access can be granted for and for what purpose.

The bank account owner (your customer) feels safe doing this because they are authenticating directly with their bank, using their online banking credentials, confident that the third party won’t see or store them.

The beauty of the US Open Banking API is that it handles the connections to all the banks (10,000+ US connections), provides a secure dialog so the account holder can authenticate, and caches the financial data so when you execute a query it comes back quickly (not having to make a round trip to the bank every time).

So, let’s dive into the video which will walk you through how to get started with the API. It will cover how to register on Mastercard Developers, create a project and add the US Open Banking API to that project, get the API credentials you need to access the API, run the Postman Collection, authenticate with the API, create a Test Customer, allow that customer to connect to their bank and grant access to one or more accounts. It will then show you how to pull that list of accounts back, query transactions, and create test transactions.

It looks like a lot but, as you will see from the video, these steps are fast and intuitive.
