Authorization

Your application uses the information registered with SkyVault to authorize itself when it is run by a user.

Requesting an authorization code

The following HTML is from the SkyVault OAuth sample and shows an application with a API Key (client_id) of l74dx104ddc00c3db4509b2d02f62c3a01234 , a redirect URI of http://localhost:8080/alfoauthsample/mycallback.html and a scope of public_api authorizing with SkyVault. You should always use the value public_api for scope.

SkyVault will ask the user for their userid and password to grant or deny access to resources for your application. If they grant access, then SkyVault will invoke the callback URI with the authorization code.

Exchanging the authorization code for an access token

Once the application has an authorization code, it can exchange this for an access token. The following HTML is from the SkyVault OAuth sample and shows an application with an authorization code of f9d9f182-700b-4c67-8235-b6ea08870872 API Key (client_id) of l74dx104ddc00c3db4509b2d02f62c3a01234 , and a key secret (client_secret) of ebf0708b9c8a46efb0115024a7a204e0 requesting an access token. Note that once the application has an authorization code, it has 10 minutes to exchange it. After that, the authorization code is invalid and the application must request a new one.

The application will get a JSON response body like this:

{
  "access_token":"87727764-3876-43b9-82a1-1ca917302ce5",
  "token_type":"Bearer",
  "expires_in":3600,
  "refresh_token":"596f6074-f432-4aeb-a162-8196213c659c",
  "scope":"public_api"
}
The following table explains the response properties :-
Property JSON Type Description
access_token string An access token that can be used to make authenticated calls using the SkyVault 2.0 API for one hour.
token_type string The type of token.
expires_in number The number of seconds the access token will be valid for. SkyVault will issue access tokens valid for one hour.
refresh_token string Once the access token expires, the application must get a new access token using this refresh token. The refresh token is valid for seven days.
scope string Always use public_api as the value of scope.

The access token can be used to make authenticated calls using the SkyVault 2.0 API for one hour. After that period, the application must get a new access token using the refresh token.

Using the access token

For simplicity the example below adds the access token to the query as a parameter. Note that the preferred method to pass the access token to SkyVault is to include it in the HTTP request header in the Authorization field in the following format:

            Value: Bearer [your access token]

This is a an example:

Bearer d1358c05-6564-4086-94b6-a7e14ce3490

The application now has an access token, and can use it to make API calls. The following HTML code is from the SkyVault OAuth sample and shows an authenticated call to the sites API.
