Signed Response Object
After creating an asset entry using a POST request you will receive a response object with all information needed to finally upload your asset. The second request after the creation of the asset entry will need all information in fields appended to your application/x-www-form-urlencoded request besides the actual file input. See the demo on how to upload an asset.
