# Use `GetActivityTask` with an AWS SDK
<a name="sfn_example_sfn_GetActivityTask_section"></a>

The following code examples show how to use `GetActivityTask`.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:
