guys, 5 days passed, can't link my ebay from 3 different browsers
please help


Ebay gives error:

{"error_id":"invalid_request","error_description":"Input request parameters are invalid.","http_status_code":400}

Please don't ask the same question multiple times. It will not speed up the response, but may add more confusion for you.
Instead, follow up on the original ticket you created.

There is no need to wait that many days to link your eBay account.
As I mentioned before, the error comes from eBay and not the sniper.
Please try to link it using incognito mode or on another PC.
I have no control over eBay side to fix it for you.
