# BLIK

BLIK transactions accounted for 75% of e-commerce volume and a 60% market share of all e-commerce in Poland for 2021. BLIK boasts over 10.1 million active users and is continuing to grow.

BLIK lets shoppers pay for online purchases directly from their preferred bank account. After choosing BLIK at checkout, shoppers are directed to BLIK's system to provide their BLIK code that authenticates and confirms payment directly from their banking app.

Contact your Customer Success Manager and sign a BLIK addendum if you want to use BLIK..

## How to configure

How you configure BLIK depends on whether you're using [DigitalRiver.js with Elements](/commerce-api/payments/payments-solutions/digitalriver.js.md) or[ Drop-in payments](/commerce-api/payments/payments-solutions/drop-in.md).

## How it works

BLIK uses a [redirect then submit (RTS) payment flow](/commerce-api/payments/building-your-workflows/flows-by-payment-type.md#redirect-then-submit-rts-payment-flow).
