Methods

All API methods are available with GET and POST requests.

Every method is available on 2 URLs:

{api_server}fb.do?method=[method_name] - e.g., https://api.ok.ru/fb.do?method=friends.get

{api_server}api/[method_group]/[method_name] - e.g., https://api.ok.ru/api/friends/get

A corresponding GET parameter should be used as {api_server}. If it is missing, https://api.ok.ru/ is used.

Parameter	Required	Type	Description
application_key	Yes	String	Application public key
sig	Yes	String	Request signature
session_key/access_token	No	String	User session. Parameter may be obligatory, optional or forbidden depending on the method
format	No	String	Format of method response; may be JSON only
call_id	No	Long	Request order number
__online	No	Boolean	Whether to mark a user as online (effective for messengers). True by default

when the session_secret_key value is absent:
- to call without session – session_secret_key = application_secret_key;
- to call in session – session_secret_key = MD5(access_token + application_secret_key), convert the value to the lower case;
take session_key/access_token away from the list of parameters, if applicable;
parameters are sorted lexicographically by keys;
parameters are joined in the format key=value;
sig = MD5(parameters_value + session_secret_key);
the sig value is changed to the lower case.
