Home B2Core API REST API The Front Office API Obtain a device fingerprint

Obtain a device fingerprint

The device_fingerprint is one of the required parameters for the methods to sign up and sign in to the B2Core UI.

Obtain a device fingerprint as follows:

  1. Create a free-form JSON string that uniquely identifies your device.

    You can create you device fingerprint using the AmIUnique online tool , and then download it in JSON format.

  2. From the downloaded JSON file, extract the userAgent data, such as:

    Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36

  3. Convert the userAgent data to a Base64 string.

    To convert JSON to Base64, you can use ReqBin:

$data = [
  'user_agent' => 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36'];

echo base64_encode(json_encode($data))

Include the Base64-encoded string that you obtained after conversion as the device_fingerprint parameter in your sign up and sign in requests.
