 Learn more about Durable Functions in [this article](../azure-functions/durable/durable-functions-overview.md). You can set up an Azure Function Activity to call the Durable Function, which will return a response with a different URI, such as [this example](../azure-functions/durable/durable-functions-http-api.md#http-api-url-discovery). Because `statusQueryGetUri` returns HTTP Status 202 while the function is running, you can poll the status of the function by using a Web Activity. Simply set up a Web Activity with the `url` field set to `@activity('<AzureFunctionActivityName>').output.statusQueryGetUri`. When the Durable Function completes, the output of the function will be the output of the Web Activity.
