## Making HTTP Requests

* **Note**\
  JSON values in the request body are strings.
* **Note**\
  JSON values in the response are strings.

## Handling Errors

* **Note**\
  If you're polling to determine the status of a request, and if Elastic Transcoder is returning HTTP status code 429 with an error code of `Provisioned Throughput Exceeded Exception` or `Throttling Exception`, consider using notifications instead of polling to determine status. For more information, see [Notifications of Job Status](https://github.com/kevinslin/aws-reference-notes/blob/main/services/amazon_elastic_transcoder/notifications.md).
