Response Headers

This operation uses only response headers that are common to most responses. For information about common response headers, see HTTP Responses.

Response Body

The JSON string in the response body returns the values that you specified when you created the preset. For more detail about the individual objects, see Settings that You Specify When You Create an Elastic Transcoder Preset.

In addition, Elastic Transcoder returns the following values.

(Automatic) Id

Identifier for the preset. You can use this value to get settings for the preset or to delete it.

(Automatic) Type

Whether the preset is a default preset provided by Elastic Transcoder (System) or a preset that you have defined (Custom).

(Automatic) NextPageToken

A value that you use to access the second and subsequent pages of results, if any. When the presets fit on one page or when you've reached the last page of results, the value of NextPageToken is null.
