Now that we have all the necessary pieces set up, let's go back to the Amazon API Console and try testing the service. For that, follow these steps:

1. Open the /WeatherServiceFunction/ANY file under the Resources option, and hit the Test option.
2. Under the method, select Get as the option.
3. For the query string, we need two inputs: the ZIP code of the city for which you want to query the current weather and the OpenWeatherMap's API key. To do this, create a query string such as zip=<<zip-value>>&appid=<<app-id>>. In this, replace the italicized values with actual inputs and form a string such as zip=10001&appid=abcdefgh9876543qwerty.
4. Hit the Test button at the bottom of the screen to invoke the API and the Lambda function.
5. If the test is successful, you will see a response with Status: 200, and in the response body, you will get the weather information in a JSON format, as follows:

If there's an error in test execution, check the logs in the bottom half of the screen to debug the issue.
