AWS SDK for JavaScript Support Client for Node.js, Browser and React Native.
Amazon Web Services Support
The Amazon Web Services Support API Reference is intended for programmers who need detailed information about the Amazon Web Services Support operations and data types. You can use the API to manage your support cases programmatically. The Amazon Web Services Support API uses HTTP methods that return results in JSON format.
-
You must have a Business, Enterprise On-Ramp, or Enterprise Support plan to use the Amazon Web Services Support API.
-
If you call the Amazon Web Services Support API from an account that doesn't have a Business, Enterprise On-Ramp, or Enterprise Support plan, the
SubscriptionRequiredExceptionerror message appears. For information about changing your support plan, see Amazon Web Services Support.
You can also use the Amazon Web Services Support API to access features for Trusted Advisor. You can return a list of checks and their descriptions, get check results, specify checks to refresh, and get the refresh status of checks.
You can manage your support cases with the following Amazon Web Services Support API operations:
-
The CreateCase, DescribeCases, DescribeAttachment, and ResolveCase operations create Amazon Web Services Support cases, retrieve information about cases, and resolve cases.
-
The DescribeCommunications, AddCommunicationToCase, and AddAttachmentsToSet operations retrieve and add communications and attachments to Amazon Web Services Support cases.
-
The DescribeServices and DescribeSeverityLevels operations return Amazon Web Service names, service codes, service categories, and problem severity levels. You use these values when you call the CreateCase operation.
You can also use the Amazon Web Services Support API to call the Trusted Advisor operations. For more information, see Trusted Advisor in the Amazon Web Services Support User Guide.
For authentication of requests, Amazon Web Services Support uses Signature Version 4 Signing Process.
For more information about this service and the endpoints to use, see About the Amazon Web Services Support API in the Amazon Web Services Support User Guide.
To install the this package, simply type add or install @aws-sdk/client-support using your favorite package manager:
npm install @aws-sdk/client-supportyarn add @aws-sdk/client-supportpnpm add @aws-sdk/client-support
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the SupportClient and
the commands you need, for example DescribeCasesCommand:
// ES5 example
const { SupportClient, DescribeCasesCommand } = require("@aws-sdk/client-support");// ES6+ example
import { SupportClient, DescribeCasesCommand } from "@aws-sdk/client-support";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation on client with command object as input. - If you are using a custom http handler, you may call
destroy()to close open connections.
// a client can be shared by different commands.
const client = new SupportClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new DescribeCasesCommand(params);We recommend using 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.
}Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// process err and data.
});The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-support";
const client = new AWS.Support({ region: "REGION" });
// async/await.
try {
const data = await client.describeCases(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.describeCases(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.describeCases(params, (err, data) => {
// process err and data.
});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;
* }
