Quick Start

To authenticate, submit a POST /v2.0/tokens request, presenting valid Rackspace customer credentials in the message body to a Rackspace authentication endpoint.


You can use either of two sets of credentials:

  • your username and password

  • your username and API key

Your username and password are the ones you use to login to the Cloud Control Panel at http://mycloud.rackspace.com/. Once you are logged in, you can use the Cloud Control Panel to obtain your API key.


Multiple users (account users) can be created for an account but, as explained in ???, users created via the API do not have access to the control panel. Control panel access for these users is coming soon.


Use the authentication endpoint for the region in which your account is based:


If you know your credentials and your authentication endpoint, and you can issue a POST /v2.0/tokens request in an API call, you have all the basic information you need to use the Rackspace Cloud Identity Service.

You can use cURL to try the authentication process in two steps: get a token; send the token to a service.

  1. Get an authentication token by providing your username and either your API key or your password. Here are examples of both approaches:

    You can request a token by providing your username and your API key.

    curl -X POST https://identity.api.rackspacecloud.com/v2.0/tokens -d
    '{ "auth":{ "RAX-KSKEY:apiKeyCredentials":{ "username":"theUserName", "apiKey":"00a00000a000a0000000a000a00aaa0a" } } }' -H "Content-type: application/json"

    You can request a token by providing your username and your password.

    curl -X POST https://identity.api.rackspacecloud.com/v2.0/tokens -d
    '{"auth":{"passwordCredentials":{"username":"theUserName","password":"thePassword"}}}' -H "Content-type: application/json"

    Successful authentication returns a token which you can use as evidence that your identity has already been authenticated. To use the token, pass it to other services as an X-Auth-Token header.

    Authentication also returns a service catalog, listing the endpoints you can use for Cloud services.

  2. Use the authentication token to send a GET to a service you would like to use. Here is an example of passing an authentication token to the Cloud Files service, using the Cloud Files service catalog endpoint that was returned along with the token.

    You can use a token and a service endpoint to tell a service that your credentials are valid.

    curl -X GET https://storage101.dfw1.clouddrive.com/v1/MossoCloudFS_aaaaaaaa-bbbb-cccc-dddd-eeeeeeee
    -H 'X-Auth-Token:11111111-aaaa-2222-bbbb-3333cccc4444' --verbose

The rest of this API Developer Guide provides reference and background information, including sample requests and responses. To learn more about the Cloud Identity Service and this API, two good places to begin are with the fundamental ideas explained in the section called “Identity concepts” and the annotated request and response in the section called “Sample Authentication Request and Response” To see examples of authentication requests using different types of c credentials, see the section called “Authentication tokens”.


You can find language binding examples that can be modified to work with the Cloud Identity service in the Rackspace Software Development Kits.
