When attempting to upload documents for account verification, the error "Invalid Parameters" is returned if the document doesn't fit the parameters and in some cases even if it does.
Make sure that the files you are trying to upload to your Kraken account follow these guidelines:
- Allowed file type extensions are: JPEG, JPG, PNG.
- Files must be at least 98KB and at most 1MB.
- Image dimensions must be a minimum of 350 x 350px and a maximum of 4096 x 4096px.
Note: we do not accept PDF files.
If you think your file is within these guidelines but you still get the error, contact support and mention "Invalid Parameters" in your message.
