Hi Commuinty,

I graduated my public webhook application and got client id, client secret and created JWT token for my app for production environment. But when I try to get an access token using these new production credentials I end up with an error:

{

"error" : "invalid_client",

"errors" : [ {

"errorCode" : "CMN-408",

"message" : "In order to call this API endpoint, one of the following permissions [ThirdPartyAppAccess] have to be granted to the authorized user.",

"parameters" : [ {

"parameterName" : "permissionsName",

"parameterValue" : "ThirdPartyAppAccess"

} ]

} ],

"error_description" : "In order to call this API endpoint, one of the following permissions [ThirdPartyAppAccess] have to be granted to the authorized user."

}

Since credentials that I use are for production environment, i use https://platform.ringcentral.com/restapi/oauth/token endpoint.

I get no error if I use sandbox credentials and https://platform.devtest.ringcentral.com/restapi/oauth/token endpoint.

The user whose JWT token is used for getting access token has Developer Admin role. In my understanding it should have "ThirdPartyAppAccess" permission.

Why I cannot get access token using production credentials for my app & user? Is that because my user belong to free account?

Best,
