I've just create a new account and I'm trying to send myself a message with the console to my Geoloqi iPhone app.
I'm able to send myself a message with the map. I can't with the console since I don't have the user_id. I can't find anything in the API to retrieve it.
If you are trying to send a message to yourself, you can use the "message/send" method with only the "text" parameter. You do not need to provide the user_id to send a message to yourself.
