When your client is adding a new bank account through the Bridge Connect, he can choose his bank on the page below.
The banks displayed are what we call the "Highlighted banks". They can be customized on your dashboard: go to an App page > Customization tab > Highlighted banks section.
If you don't set any highlighted banks, we will display default ones for you, depending on the country you set up in "connect an item" API call or the browser language of your client if you haven't set up any country.
