Origin_endpoints id

URI

/origin_endpoints/ id

HTTP Methods

GET

Operation ID: DescribeOriginEndpoint

Provides details about an endpoint.

AWS CLI Request Syntax

aws mediapackage describe-origin-endpoint --id <endpointId>

Path Parameters

Name	Type	Required	Description
id	String	True	Identifier for the object that you are working on.

Responses

Status Code	Response Model	Description
200	OriginEndpoint	200 OK response Endpoint details are returned successfully.
403	None	403 Forbidden response AWS Elemental MediaPackage cannot authorize the request, possibly due to insufficient authentication credentials.
404	None	404 Not Found response AWS Elemental MediaPackage did not find a representation of the target resource.
422	None	422 Unprocessable Entity response AWS Elemental MediaPackage could not process the instructions in the body of the request.
429	None	429 Too Many Requests response Too many requests have been sent in a given amount of time.
500	None	500 Internal Server Error response An unexpected condition prevented AWS Elemental MediaPackage from fulfilling the request.
503	None	Service unavailable response AWS Elemental MediaPackage can't currently complete the request, usually because of a temporary overload or maintenance.

PUT

Operation ID: UpdateOriginEndpoint

Updates a specific endpoint. When you submit the request to update an endpoint, include all necessary attributes in the request, even the ones that aren't being updated. If you send only the updated attributes, then all modifiable attributes that weren't specifically included in the request will reset to default values. For example, if you are using a 30 second time delay and submit a request to only update the endpoint description, then the time delay will update to zero (disabled). We recommend that you submit a GET request to obtain the endpoint's existing attributes and submit an updated version of the GET response body when you are updating an endpoint.

You can't change the id attribute or any other system-generated attributes.

AWS CLI Request Syntax

aws mediapackage update-origin-endpoint 
--id <endpointId> 
--dash-package | --hls-package | --mss-package} <packagingSettings>
[--description <value>]
[--manifest-name <value>]
[--startover-window-seconds <value>]
[--time-delay-seconds <value>]
[--whitelist <value>]

For nested parameters, such as those for packagingSettings, you can reference a JSON file file://<fileName>.json that holds all of the attributes.

Path Parameters
