Arbitrary properties can be associated with an access token.
Here, property is a JSON object which has entries named key and value. The types of the entry values are string. Literally, key represents the key of the property and value represents the value of the property.
The JSON below is an example of a property whose key and value are example_parameter and example_value, respectively.
{
"key":"example_parameter",
"value":"example_value"
}
For example, if the property above is associated with an access token, an access token response from your authorization server will look like the examples below.
Example in Implicit Flow
Location: http://localhost:8880/api/mock/redirection/5593494639
#access_token=pNj1h24a4geA_YHilxrshkRkxJDsyXBZWKp3hZ5ND7A
&token_type=Bearer&expires_in=86400&scope=
&example_parameter=example_value
Example in Authorization Code Flow
{
"access_token":"pNj1h24a4geA_YHilxrshkRkxJDsyXBZWKp3hZ5ND7A",
"token_type":"Bearer",
"expires_in":86400,
"scope":null,
"example_parameter":"example_value"
}
As you can see, a property, example_parameter=example_value, is included in the redirect URI in “Example in Implicit Flow” and in the JSON in “Example in Authorization Code Flow”. The property is passed to the client application. However, there may be some cases where you want to associate properties with an access token but don’t want to show them to the client application. In such a case, add hidden=true like below when you prepare a property.
{
"key":"example_parameter",
"value":"example_value",
"hidden":true
}
Properties associated with an access token can be obtained by using Authlete’s /api/auth/introspection API (which is the API to get information about an access token). A response from the introspection API contains associated properties in the format as shown below.
{
"type":"introspectionResponse",
"resultCode":"A056001",
"resultMessage":"[A056001] The access token is valid.",
"action":"OK",
"clientId":5008706718,
"existent":true,
"expiresAt":1461369117000,
"properties":[
{
"hidden":false,

"value":"example_value"
}
],
"refreshable":false,
"responseContent":"Bearer error=\"invalid_request\"",
"subject":"user123",

}
Note that the response from Authlete’s introspection API is different from the format defined in RFC 7662 See 4. Introspect Access Token in Authlete Definitive Guide for details.

As the value of action contained in the above response from /auth/authorization/issue API is LOCATION, HTTP status “302 Found” should be returned to the client application.

Issue an authorization code by calling /auth/authorization/issue API. Here, specify properties to associate with an authorization code using properties parameter. The specified properties will finally be associated with an access token. Note that additional properties can be passed to /auth/token API which will be called later, too. Therefore, in the authorization code flow, properties don’t necessarily have to be given to /auth/authorization/issue API even if properties need to be associated with an access token.

In Client Credentials Flow, a refresh token (refresh_token) is not issued. See RFC 6749 for details.
Pass a request from a client to a token endpoint, grant_type=password&client_id=5008706718&username=u&password=p, to /auth/token API. When grant_type is password, the value of properties parameter given to /auth/token API is simply discarded. So, it is not specified here. Instead, properties parameter is used later when /auth/token/issue API is called. Note that /auth/token/issue API exists only for grant_type=password.

When the value of action in a response from /auth/token API is PASSWORD, it means that Resource Owner Password Credentials Flow is being used. In this case, as the first step, user authentication needs to be performed using username and password presented by the client application. The values of username parameter and password parameter in the original token request are contained in a response from /auth/token API without any modification. In the above example, the value of username is u and that of password is p.
As a result of user authentication, the unique identifier of the user should be determined. Call /auth/token/issue API with the unique identifier as the value of subject parameter. Also, the API call requires ticket which has been issued from /auth/token API in advance. If some properties need to be associated with an access token, properties request parameter should be added, too.

Properties to associate with an access token should be specified using properties parameter. In this example, the property is extra_parameter=extra_value and this is a bit different from example properties used so far.

}
When grant_type is refresh_token, properties passed to /auth/token API are treated as additional properties for the access token which is coupled with the presented refresh token. The value of refresh_token parameter in the above example is the refresh token which has been issued as a result of “4. How to simulate Authorization Code Flow by curl”. And the access token which is coupled with the refresh token already has two properties, example_parameter=example_value and additional_parameter=additional_value. Therefore, as a result of adding extra_parameter=extra_value on /auth/token API call, a newly issued access token will have three properties.
As the value of action contained in the above response from /auth/token API is OK, HTTP status “200 OK” should be returned to the client application. When the value of action contained in a response from /auth/token API is OK, the value of responseContent is the value that should be used as the value of the response body. Using these pieces of information, a response like below should be returned to the client application.
