Required Headers
To enhance the security and fraud prevention of our API, we require that you include a
ratio-device-fingerprint header in your API calls. This information helps us to protect user accounts by detecting anomalous behaviour.The
ratio-device-fingerprint header must be a base64 encoding of a stringified JSON object that contains the following fields:ip: IP address of the request- Browser-based implementations:
userAgent: The user agent of the browser that is interacting with your website.
- Mobile-based implementations:
os: The operating system on which application is running. (e.g. iOS, Android)osVersion: The operating system version on which application is running. (e.g. 10.3.1, 7.1.1)deviceManufacturer: The manufacturer of the device on which application is running. (e.g. Samsung, Apple, LG)deviceModel: The model of the device on which application is running. (e.g. SM-G920x, iPhone8,1)deviceUniqueId: The unique ID of the device on which application is running. For iOS, send the IFV identifier. For Android, send the Android ID.
For example, a browser-based request from a Windows 10 machine using Chrome would have a header like this:
ratio-device-fingerprint: eyJpcCI6IjE5Mi4xNjguMC4xIiwidXNlckFnZW50IjoiTW96aWxsYS81LjAgKFdpbmRvd3MgTlQgMTAuMDsgV2luNjQ7IHg2NCkgQXBwbGVXZWJLaXQvNTM3LjM2IChLSFRNTCwgbGlrZSBHZWNrbykgQ2hyb21lLzk0LjAuNDYwNi4xMjEgU2FmYXJpLzUzNy4zNiJ9
The stringified JSON object before encoding is:
"{\"ip\":\"192.168.0.1\",\"userAgent\":\"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.121 Safari/537.36\"}"
A device-based request from an Android phone using Samsung Galaxy S21 would have a header like this:
ratio-device-fingerprint: eyJpcCI6IjE5Mi4xNjguMC4yIiwib3MiOiJBbmRyb2lkIiwib3NWZXJzaW9uIjoiMTEiLCJkZXZpY2VNYW51ZmFjdHVyZXIiOiJTYW1zdW5nIiwiZGV2aWNlTW9kZWwiOiJHYWxheHkgUzIxIiwiZGV2aWNlVW5pcXVlSWQiOiJhYmNkMTIzNC1lZmdoLTU2NzgtaWprbC03ODkwIn0=
The stringified JSON object before encoding is:
"{\"ip\":\"192.168.0.2\",\"os\":\"Android\",\"osVersion\":\"11\",\"deviceManufacturer\":\"Samsung\",\"deviceModel\":\"Galaxy S21\",\"deviceUniqueId\":\"abcd1234-efgh-5678-ijkl-7890\"}"
Please note that the stringified JSON object must be valid and well-formed.
