Generate Signature using NodeJS

To generate the signature, you will need create a key pair of private key and public key. You will share the public key with Finserve and use the private key to generate the signature.

Why Signature?

To ensure the security of your transactions or requests, Finserve have implemented security controls that ensure that transactions can only be initiated by you and no one else.

Get Started

If you don't have a key pair run node index.js and open your browser at http://127.0.0.1:1337:

1. To generate your key pair - Public and Private key,
2. Save your keys separately in current directory,
3. Build a String of concatenated values of the request fields with the following order: e.g. countryCode, accountId for Account balance,
4. Sign the result with previously created Private Key and Base64 encoded
