How it works with TransactionLink

BIG API uses 1 core product to operate:

BIG API required national ID number or company number to be able to scan it's database for credit score. You can pull that data from a customer's account and feed it to the BIG API app to get a response.

After you pull identity data, it gets automatically fed to the BIG API app. In return you get a detailed history of customer's liabilities and an overall scoring assigned by BIG.
