Permission Error Message when Creating Account

Hey there,

when I run following query to the sandbox api without ?RejectDuplicateCard, everything seems to be working. But if I add it I get following error message {"SC":403,"EC":"3C4E1019","EM":"Permission"}

The call itself:
curl --request POST \ --url "https://api.sandbox.tabapay.net:10443/v1/clients/xxxxxxxxxxxxxxxxxxxxxx/accounts?RejectDuplicateCard" \ --header 'Accept: application/json' \ --header 'Authorization: Bearer ....wALbGw' \ --header 'Content-Type: application/json' \ --data '{"card":{"keyID":"A3sFxQ4DUAq8gv5HVUa2bw","data":"Awqfi08r78BuuGilyuse7A_ShgdjpyajZlZ0vFB1DkcnzrR9tw0Gy-Tdd-gWBmjSAaJxI9USmK4nFMWoEHQpuCwSM5ppo4ZD_g-5Sbzz6rHTuHAUtrJ5Uko_l3RQardVXrXocdm7IQQPlGFezVsC5daf3GKm90PWj_skXlCN3AQRYOzD6V6pw3Tms5LfZLKmbfLpx64q9rDuiS0t_XX64xSoj-IE78ftlSdRljHRZXHo34Amf7LoD-WSSzsaigP005-Bnuy5YNpXo1EukfTiH61ahRXfWfpTNB_t6e28xj8hYMSHynHvPcaR80J7k9vZdL1EddwDEYvbjSxHHBNzVg=="},"owner": {"name": { "first": "John","last": "Customer"},"address": {"line1": "465 Fairchild Drive","line2": "Suite 222","city": "Mountain View","state": "CA","zipcode": "94043"},"phone": {"number": "4159808222"}},"referenceID": "1"}'
