UDAPI100060 - Resource Not Found error while accessing API v2 authorization URL

Dear Upstox Developer Team,

I have created an application in my developer account named “Optionlogy” and obtained the API Key:

b1bde389-1e59-49fc-9df1-28b839752da3

When I try to access the OAuth URL for v2:
https://api-v2.upstox.com/oauth/authorize/?client_id=b1bde389-1e59-49fc-9df1-28b839752da3&redirect_uri=https://127.0.0.1&response_type=code

…I receive this error:
{
“status”: “error”,
“errors”: [
{
“errorCode”: “UDAPI100060”,
“message”: “Resource not Found.”
}
]
}

Customer support redirected me here. Please confirm:

  1. Is API v2 access enabled for my app?
  2. Is there anything I need to configure like callback URL, permissions, etc.?

Thank you,
