I have an app with Platform type as "Password Flow: and "Refresh Token" . I am using postman to access token and I get below error.
{
"error": "invalid_grant",
"error_description": "Invalid resource owner credentials",
"errors": [
{"errorCode": "OAU-140","message": "Invalid resource owner credentials"}
]
}
Below is what I have tried:
- https://platform.devtest.ringcentral.com/restapi/oauth/token? along with parameters - username, password, extension and grant_type=password.
- Auth - Auth Basic used username = Client_id and password =Client Secret.
I do see authentication is added in header.
I have tested auth using the link below, using the same parameters and client id/secret.

Could you please help me in fixing the error.
Kindly let me know if I am using incorrect method.
Thank you.
First of all you need to keep in mind that in body, we need to pass the parameters in following way :
username=<account phone number>&password=<account password>&extension=<your extension>&grant_type=refresh_token&refresh_token=<the refresh token generated>
username should be the phone number
In header part
"Authorization",:"Basic <ClientID:ClientSecret in base 64>
You need to convert ClientID and ClientSecret into base64.
Remaining all seems fine.
Make sure you have done the same
