Getting Started

COMING SOON! Be one of the first to access our Account Token solution by signing up.

Account verification customers providing digital payment services can eliminate the risk of storing users' sensitive financial account information using Account Token endpoints. The endpoints allow customers to create an account-specific token that the payment processors can use to retrieve account information.

Our payment processor partners can use this token to retrieve the following account information to process payments:

  • Account holder information such as name, email, phone number, address, etc.
  • Account information including account name, account number, type, transfer code (for example, the routing number of the bank account in the US), etc.
  • Account balance information.

Sandbox Environment

For Customers

The Sandbox environment is available free once you register for a developer account. Sandbox comes enabled with five pre-configured users. It does not allow you to register new users. It is also restricted to using sample data for security reasons. Once you're comfortable and want to work with live transaction data, we recommend moving to the free Launch Tier. This guide assumes you are using the Sandbox environment.

For Payment Processors

Once you sign up to use our Account Token solution, you will receive a welcome mail containing your credentials and instructions on setting up and using the Sandbox environment.


Account Verification starts with your user authenticating and selecting an account at any of the thousands of banks we support. To accomplish this, FastLink saves you from dealing with complex technical interactions and managing disparate user experiences to connect to and authenticate with those banks. FastLink also helps unify financial institutions that support Open Banking and those without a single managed experience, ensuring that your application always utilizes the most modern experience available.

The FastLink documentation provides many more details about FastLink and how you can use it to meet your requirements. The FastLink Demo will show you the user experience of linking accounts, while the Configuration Tool Demo will show you how you can customize FastLink to meet your requirements and match the look and feel of your application.
