I guess this is a credential issue ?

Your first problem and second problem are completely different. Don't say "...Thanks but it still does not work."

Your first problem was the "Observable" module was not installed. Simply install the missing lib and try again.

Your second problem is purely about wrong username/password. All you need is to make sure the username, password and extension number (if specified) must be correct. One way to check is to login your account service web (remove the "devtest" if login your production account). If you can login that page with the user credentials, you should be able to login your app using the same credentials.

Thanks Phong Vu for underlying the two different errors. I did not understand those, hence my previous answer. Of course If i understood I would not have written this answer.

This is clear now, i understand what the problems are. I'll follow your advice to log with the user credentials. I am looking for the library 'Observable', is it in https://github.com/ringcentral/ringcentral-python ? I am unable to locate it.

Thanks Anirban, i succeeded in running the demo described here https://github.com/grokify/ringcentral-demos-oauth/tree/master/python-bottle until I click on the button on the web page

RingCentral 3-Legged OAuth Demo in Python,

then I have this message : did i miss something ? Thanks in advance
