Invalid resource owner credentials using the API Explorer

Hi
My app is in production now.

After calling login function I got this error message

"error" : "invalid_grant",

"errors" : [ {

"errorCode" : "OAU-140",

"message" : "Invalid resource owner cre (truncated...)

I use live credentials as following:

RINGCENTRAL_ID=xxxxxxxxxxyBSTB7w

RINGCENTRAL_SECRET=xxxxxxxxxxxxxxxxxxxx

RINGCENTRAL_URL=https://platform.ringcentral.com

RINGCENTRAL_USERNAME="xxxxxxxxx4735"

RINGCENTRAL_PASSWORD="xxxxxxxxxxxx"

RINGCENTRAL_EXTENSION="101"

maybe i have a wrong MVP premium account linked to my app?

can you please confirm the credentials

Hi Andrew you need to use your sandbox credentials in order to test using API Explorer. Also make sure the given application has permission for that API call.
