Description

AWS SDK for JavaScript PaymentCryptography Client for Node.js, Browser and React Native.

Amazon Web Services Payment Cryptography Control Plane APIs manage encryption keys for use during payment-related cryptographic operations. You can create, import, export, share, manage, and delete keys. You can also manage Identity and Access Management (IAM) policies for keys. For more information, see Identity and access management in the Amazon Web Services Payment Cryptography User Guide.

To use encryption keys for payment-related transaction processing and associated cryptographic operations, you use the Amazon Web Services Payment Cryptography Data Plane. You can perform actions like encrypt, decrypt, generate, and verify payment-related data.

All Amazon Web Services Payment Cryptography API calls must be signed and transmitted using Transport Layer Security (TLS). We recommend you always use the latest supported TLS version for logging API requests.

Amazon Web Services Payment Cryptography supports CloudTrail for control plane operations, a service that logs Amazon Web Services API calls and related events for your Amazon Web Services account and delivers them to an Amazon S3 bucket you specify. By using the information collected by CloudTrail, you can determine what requests were made to Amazon Web Services Payment Cryptography, who made the request, when it was made, and so on. If you don't configure a trail, you can still view the most recent events in the CloudTrail console. For more information, see the CloudTrail User Guide.

Installing

To install this package, use the CLI of your favorite package manager:

• npm install @aws-sdk/client-payment-cryptography
• yarn add @aws-sdk/client-payment-cryptography
• pnpm add @aws-sdk/client-payment-cryptography

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the PaymentCryptographyClient and the commands you need, for example ListAliasesCommand:

// ES5 example
const { PaymentCryptographyClient, ListAliasesCommand } = require("@aws-sdk/client-payment-cryptography");

// ES6+ example
import { PaymentCryptographyClient, ListAliasesCommand } from "@aws-sdk/client-payment-cryptography";

Usage

To send a request:

• Instantiate a client with configuration (e.g. credentials, region).
  • See docs/CLIENTS for configuration details.
  • See @aws-sdk/config for additional options.
• Instantiate a command with input parameters.
• Call the send operation on the client, providing the command object as input.

const client = new PaymentCryptographyClient({ region: "REGION" });

const params = { /** input parameters */ };
const command = new ListAliasesCommand(params);

Async/await

We recommend using the await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
} finally {
  // finally.
}

Promises

You can also use Promise chaining.

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });

Aggregated client

The aggregated client class is exported from the same package, but without the "Client" suffix.

PaymentCryptography extends PaymentCryptographyClient and additionally supports all operations, waiters, and paginators as methods. This style may be familiar to you from the AWS SDK for JavaScript v2.

If you are bundling the AWS SDK, we recommend using only the bare-bones client (PaymentCryptographyClient). More details are in the blog post on modular packages in AWS SDK for JavaScript.

import { PaymentCryptography } from "@aws-sdk/client-payment-cryptography";

const client = new PaymentCryptography({ region: "REGION" });

// async/await.
try {
  const data = await client.listAliases(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listAliases(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks (not recommended).
client.listAliases(params, (err, data) => {
  // process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  const { requestId, cfId, extendedRequestId } = error.$metadata;
  console.log({ requestId, cfId, extendedRequestId });
  /**
   * The keys within exceptions are also parsed.
   * You can access them by specifying exception names:
   * if (error.name === 'SomeServiceException') {
   *     const value = error.specialKeyInException;
   * }
   */
}
