Payment Gateway Issues

Hey guys I keep running into this problems

So this problems occur while finalizing Idk why, do you have any idea why?

There's the error:

{
    "status_code": 401,
    "error": {
        "message": "You did not provide an API key. You need to provide your API key in the X-Authorization header (e.g. 'X-Authorization: YOUR_API_KEY').",
        "type": "authentication_error"
    }
}
