Use the Set OAuth v2 policy to update access token attributes.

As mentioned by above use the Set Oauth v2 policy as found in the documentation

http://docs.apigee.com/api-services/reference/set-oauth-v2-info-policy

example

<SetOAuthV2Info name="SetOAuthV2Info"> 
  <AccessToken ref="access_token"></AccessToken>
  <Attributes>
    <Attribute name="departmentId" ref="department_id"></Attribute>
  </Attributes>
</SetOAuthV2Info>

note: in this scenario you would have already validated the access token and the access_token lives in the access_token variable.
