Answer 1

The easiest thing would be to POST it.
Here's the documentation on how to construct a POST request for CloudWatch: https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/making-api-requests.html#CloudWatch-API-requests-using-post-method
Below is an example request you can use. Save the JSON below to a file and import into postman. You will also need to create an Environment and provide ACCESS_KEY_ID, SECRET_ACCESS_KEY and REGION.
