Readme
@highnoteplatform/secure-inputs
Note: This library is in a pre-release phase. Prior to the release of version
1.0.0, breaking changes may be introduced.
The Highnote Secure Inputs SDK allows you to accept sensitive data from your customer securely and seamlessly using iframes. This allows you to avoid sensitive data (like PCI-scoped data) flowing through your servers or being accessible to scripts running on your page.
Usage
Secure Inputs Fields
Note: Read the full documentation here.
Installation
With npm:
npm i @highnoteplatform/secure-inputsWith yarn:
yarn add @highnoteplatform/secure-inputsGenerate a client token
On your server, generate a client token using the GraphQL API.
See the generatePaymentCardClientToken docs.

mutation GeneratePaymentCardClientToken(
$input: GeneratePaymentCardClientTokenInput!
) {
generatePaymentCardClientToken(input: $input) {
... on ClientToken {
value
expirationDate
}
}
}Input variables
{
"input": {
"paymentCardId": "MC43LjE=",
"permissions": ["SET_PAYMENT_CARD_PIN"]
}
}Response
{
"data": {
"generatePaymentCardClientToken": {
"value": "TOKEN",
"expirationDate": "2022-02-07T20:04:50.633Z"

import { renderFields } from "@highnoteplatform/secure-inputs";
const { unmount } = await renderFields({
onSuccess: (element) => {
// Inform the user on success
},
onError: (error) => {
// Handle errors
},
// Specify the individual fields to render data into
elements: {
pin: {
clientToken: "client token from server",
// This is the same paymentCardId used to generate the token
paymentCardId: "MC43LjE=",
selector: "#pin",
},
});Card Tokenization (Card Number Only)
For card tokenization with only the card number (PAN), you can use the simplified configuration.
import { renderFieldsForTokenization } from "@highnoteplatform/secure-inputs";
import type { SecureInputsTokenizationConfig } from "@highnoteplatform/types";
const config: SecureInputsTokenizationConfig = {
clientToken: "client token from server",
onSuccess: (paymentMethodToken) => {
// Handle successful tokenization
console.log("Tokenized card:", paymentMethodToken);
},
onError: (error) => {
// Handle errors
console.error("Tokenization failed:", error);
},
onReady: () => {
// Fields are ready for input
console.log("Secure inputs ready");
},
// Only cardNumber is required
elements: {
cardNumber: {
selector: "#card-number",
},
},
};
const { submit, unmount } = await renderFieldsForTokenization(config);
// Submit the form when ready
document.getElementById("submit-button")?.addEventListener("click", () => {
submit();
});
