Usage

Here is an example of how to use the getPayspecInvoiceUUID function in JavaScript:

const payspec = require('payspec-typescript-library');

const invoiceData = {
  payspecContractAddress: '0x1234567890123456789012345678901234567890',
  description: 'Example Invoice',
  nonce: '1234567890123456',
  token: '0x0000000000000000000000000000000000000000',
  totalAmountDue: '1000000000000000000',
  payToArrayStringified: '["0x1111111111111111111111111111111111111111", "0x2222222222222222222222222222222222222222"]',
  amountsDueArrayStringified: '[500000000000000000, 500000000000000000]',
  expiresAt: 1648694400
};

const uuid = payspec.getPayspecInvoiceUUID(invoiceData);

console.log(uuid);
