How it works?

Through a simple function call in the background, bank details can be checked as soon as the user has entered the data.

This will therefore insure only valid details are stored, reducing rejections and delays from the bank.

By using the most up-to-date EISCD data we can ensure that the validation process is always accurate, reducing users most common typing errors.


We have defined the most common API request queries but we also understand that each customer is unique and might need custom end points.

This is a premium service that will need bespoke development. If you would like to take advantage of this, please contact our sales team at or fill up the form.
