Confirm subscription API not working

I have created a subscription with id e770af73-cc7f-4494-MASKED . After getting the token I am using POST request to hit the endpoint

curl --location --request POST 'https://services.sentinel-hub.com/api/v1/dataimport/subscriptions/e770af73-cc7f-4494-bb65-f793005ed166/confirm' \

--header 'Authorization: Bearer eyJraWQiOiJzaCIsImFsZyI6IlJTMjU2In0.eyJzdWIiOiI5YWM1*************************

I am getting following response from the request

{

    "error": {

        "status": 401,

        "reason": "Unauthorized",

        "message": "Invalid api-key.",

        "code": "COMMON_UNAUTHORIZED"

    }

}

I have doubled check the possible details but still the not able to confirm my subscription of Planet data.
