When uploading documents for account verification, the error "Invalid Parameters" is returned if the file doesn't fit our technical parameters (and in some rare cases, even if it does). 

Make sure that your upload files meet these guidelines:

If one or more of these parameters are not met, your upload will fail.

If your file is within these guidelines but you still get the error, please take a screenshot of your image and try to upload that instead.

If it still does not work, please contact support and mention "Invalid Parameters" in your message.
