Install the Bolt Tokenizer

Bolt’s tokenizer is a public package on NPM and can be used to implement custom back-office integrations, such as direct payment processing, when also paired with the authorization endpoint.

Tokenization is handled in a separate service from Bolt Checkout and is PCI compliant. See the Authorization endpoint’s request body schema for more information.

How to use the Tokenizer

  1. Import the package:
import TkClient from @boltpay/tokenizer;
  1. Create a new instance of the TkClient object:
const tkClient = new TkCLient(env, async (url, request) => fetchFunc(url, request));

In the initial call, the env value can be to either sandbox or production. fetchFunc is a function used to send HTTP requests (for example, you could use the javascript built-in function fetch).

  1. Call the postToken method with the credit card information:
const cardToken = tkClient.postToken(credit_card);
  1. Authorize using the v1/merchant/transactions/authorize endpoint found here.

Objects & Values

credit_card is the javascript object {cc: credit card number, cvv: cvv}

postToken returns the javascript object {token, expiry, last4, bin, network}

  • token — the token is the newly generated credit card token
  • expiry — the date at which the token expires
  • last4 — the last 4 digits of the card number
  • bin — the credit card bin
  • network — the credit card network


import TkClient from @boltpay/tokenizer;

const tkClient = new TkCLient("sandbox", async (url, request) => fetch(url, request));
const cardToken = tkClient.postToken({cc: "4111111111111111", cvv: "000"});
