• Set your X-NDAX-FILE-HASH header to the sha256 hash (in a byte array) of your file contents and encode this data to base64 string.

• Make sure to use {} as your body when signing your request. If you use your actual request body to sign you will receive and Invalid Client Signature.

• Ensure that your file is not larger than 10mb.

• Remember to base 64 encode your file before sending it to us.
