V3 APIs Resource Forbidden

Hi @IntegrationSupport Team,
We were trying the v3 apis but seems we do not have access to the v3 APIs.

Getting following error :
{
“code”: “900908”,
“message”: "Resource forbidden ",
“description”: “User is NOT authorized to access the Resource. API Subscription validation failed.”
}

Client Id : SBX_002789

Can someone please help us get access to the v3 version?
