In addition to token-based authentication Cloud Feeds also supports
basic authentication by using your Rackspace cloud account username and
API key.
Warning
Basic authentcation cannot be used for Archiving Configuration API operations.
To make a request to the Cloud Feeds API with basic authentication, you need to issue a cURL call directly against the requested end point by providing the username and API key directly in the call as shown here:
curl -u <username:api-key> -X <method> https://endpointURL/
The following example shows how to retrieve the feeds catalog by using basic authentication:
curl -u username:user_api_key –X GET https://atom.test.ord1.us.ci.rackspace.net/
The following example show how to retrieve an event by using basic authentication:
curl -u username:user_api_key –X GET https://atom.test.ord1.us.ci.rackspace.net/usagesummary/bigdata/events
