There are more AWS SDK examples available in the [AWS Doc SDK Examples](https://github.com/awsdocs/aws-doc-sdk-examples) GitHub repo.

# Code examples for Migration Hub using AWS SDKs
<a name="migration-hub_code_examples"></a>

The following code examples show you how to use AWS Migration Hub with an AWS software development kit (SDK).

*Actions* are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.
