# AWS STS code examples for the SDK for C++

## Overview

Shows how to use the AWS SDK for C++ to access the AWS Security Token
Service (AWS STS) to acquire temporary credentials that grant specific permissions.

*AWS provides AWS STS as a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (IAM) users or for users you authenticate (federated users).*

## ⚠️ Important

* Running this code might result in charges to your AWS account. 
* Running the tests might result in charges to your AWS account.
* We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege). 
* This code is not tested in every AWS Region. For more information, see [AWS Regional Services](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services).

## Code examples

### Single actions

Code excerpts that show you how to call individual service functions.

- [Assume a role](./assume_role.cpp) (assumeRole)

## Run the examples

### Prerequisites

Before using the code examples, first complete the installation and setup steps
of [Getting started](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/getting-started.html) in the AWS SDK for
C++ Developer Guide.
This section covers how to get and build the SDK, and how to build your own code by using the SDK with a
sample Hello World-style application.

Next, for information on code example structures and how to build and run the examples, see [Getting started with the AWS SDK for C++ code examples](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/getting-started-code-examples.html).

## Tests

⚠️ Running the tests might result in charges to your AWS account.

```sh
   cd <BUILD_DIR>
   cmake <path-to-root-of-this-source-code> -DBUILD_TESTS=ON
   make
   ctest 
```
