Redirect SCA SDK

This is a small SDK helping TPPs to implement BANKSapi's Redirect Component on their domain to be compliant with the regulatory requirements of XS2A's redirect SCA flow.

Build

npm install

then either: npm run start to enter development mode or npm run build to build a bundled version to dist/.

Usage

The SDK (in this case more of a library) provides you with these methods.

• redirectSca.initState()
• redirectSca.returnNextRedirect()
• redirectSca.continueRedirect()
• redirectSca.abortSca()

This SDK tries to propagate errors from the banking provider. Errors show up to the TPP in form of the query parameter redirect-sca-error appended to the callback URL.

You can learn more about them by looking into the documentation inside of src/redirect-sca-sdk.js

Minimal example usage after embedding the SDK from dist/ in a <script>-tag:

await redirectSca.initState();
let nextRedirectDirection = await redirectSca.returnNextRedirect(); // CUSTOMER or PROVIDER
console.log(nextRedirectDirection);
redirectSca.continueRedirect();
