Invalid resource owner credentials in Production

First of all, don't reveal both app client id and client secret in public (I deleted part of it). Treat the secret as a sensitive information.

Having a look at your account, you have only one user in the production and the user extension number is 0. So why you login with "101"? That was the reason you could not login.

Thanks for looking out after me! I put 101 because that's what was in the JSON download. As you indicated, 0 worked.

Thanks!

hey @Phong Vu I have a similar issue and got the same error. I usually log in with my email. Should I put email or phone number as username?

My clientId = Y5UjfttkTeSF2S8V04zgOg

Parameters:

You login with the main company phone number and extension number 101, which is the super admin. Are you the super admin (101)? If not, use a correct extension number. Otherwise, double check your login credentials by login the account web service at https://service.ringcentral.com, if you can log in the site, you should be able to login your app with exact credentials.
