Calling the API by making HTTP Query requests

This section contains general information about using the Query API for AWS Account Management. For details about the API operations and errors, see the API Reference.

Note

Instead of making direct calls to the AWS Account Management Query API, you can use one of the AWS SDKs. The AWS SDKs consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, and more). The SDKs provide a convenient way to create programmatic access to AWS Account Management and AWS. For example, the SDKs take care of tasks such as cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see Tools for Amazon Web Services.

With the Query API for AWS Account Management, you can call service actions. Query API requests are HTTPS requests that must contain an Action parameter to indicate the operation to be performed. AWS Account Management supports GET and POST requests for all operations. That is, the API doesn't require you to use GET for some actions and POST for others. However, GET requests are subject to the limitation size of a URL. Although this limit is browser dependent, a typical limit is 2,048 bytes. Therefore, for Query API requests that require larger sizes, you must use a POST request.

The response is an XML document. For details about the response, see the individual action pages in the API Reference.

Endpoints

AWS Account Management has a single global API endpoint that is hosted in the US East (N. Virginia) AWS Region.

For more information about AWS endpoints and Regions for all services, see Regions and Endpoints in the AWS General Reference.

HTTPS required

Because the Query API can return sensitive information such as security credentials, you must use HTTPS to encrypt all API requests.

Signing AWS Account Management API requests

Requests must be signed using an access key ID and a secret access key. We strongly recommend that you don't use your AWS root account credentials for everyday work with AWS Account Management. You can use the credentials for an AWS Identity and Access Management (IAM) user or temporary credentials such as you use with an IAM role.

To sign your API requests, you must use AWS Signature Version 4. For information about using Signature Version 4, see Signing AWS API requests in the IAM User Guide.
