Biometric KYC

Required Class: SmileIdentityCore Class

Running Biometric KYC on PHP

  1. Get your Smile ID Partner ID

  2. Get your API Key

  3. Create a Callback Endpoint

  4. Get your user's Selfie images

  5. Get the ID information from your users

  6. Submit the Job to Smile ID

  7. Interpret your results

Get your Partner ID

You can find your Partner ID in the menu list when logged into the portal.

Get your API Key

Your API Key is also in the developer section of the portal.

  • Click on the Generate New API Key button

  • Copy your api key (ensure you are in the right environment)

Create a Callback Endpoint

Responses from this product are asynchronous (based on various actions we carry out on the product) and are sent as soon as they are ready, you will need to setup a callback when submitting a job. You can read about creating a Callback URL here.

The size of the payload sent to your callback varies based on the size of image returned by the ID authority. We recommend your callback should accept payloads up to 1.5MB in size.

Get the User's Selfie

To successfully run Biometric KYC jobs you need to submit the user's selfie. There are two types of selfies that can be submitted

  • Selfie - a single colour-image selfie of user

  • (optional but required for proof of live) Liveness images - 8 colour images of user

The selfies can either be submitted as files (with the path to the image specified during submission) or as base64 encoded strings.

We recommend that you use our Web SDK to capture both of these types of images

Get the ID information from your users

To submit an Biometric KYC job you need the ID information of your user. Depending on the ID type you are attempting to query, the required information varies. For the comprehensive list of required information for each ID Type, check the Supported ID Types section of the docs.

Submit the Job to Smile ID

You can copy the sample code below and edit with your partner and job details.

<?php
require 'vendor/autoload.php';

// Initialize
$partner_id = "<Put your partner ID here>"; // login to the Smile ID portal to view your partner id
$default_callback = "<Put your default callback here>"; //callback is only required if you are running an asynchronous job
$api_key = "<Put your API key here>"; // copy your API key from the Smile ID portal
$sid_server = "<0 or 1>"; // Use '0' for the sandbox server, use '1' for production server

$connection = new SmileIdentityCore(
    $partner_id,
    $default_callback,
    $api_key,
    $sid_server    
);

// Create required tracking parameters
$partner_params = array(
    'job_id' => "<put your unique job ID here>",
    'user_id' => "<put your unique ID for the user here>",
    'job_type' => 1
);

// Create image list
// image_type_id Integer
// 0 - Selfie image jpg (if you have the full path of the selfie)
// 2 - Selfie image jpg base64 encoded (if you have the base64image string of the selfie)
// 4 - Liveness image jpg (if you have the full path of the liveness image)
// 6 - Liveness image jpg base64 encoded (if you have the base64image string of the liveness image)
$image_details = array(

    array(
        "image_type_id" => <0 | 2>,
        "image" => "<full path to selfie image or base64image string>"
    ),
    array( // Not required if you don't require proof of life (note photo of photo check will still be performed on the uploaded selfie)
        "image_type_id" => <4 | 6>,
        "image" => "<full path to liveness image or base64 image string>"
    )
);

// Create ID number info
$id_info = array(
    'first_name' => "<name>",
    'middle_name' => "<middle>",
    'last_name' => "<surname>",
    'country' => "<2-letter country code>",
    'id_type' => "<id type>",
    'id_number' => "<valid id number>", // Always required
    'dob' => "<date of birth>", // yyyy-mm-dd
    'entered' => "true" // MUST BE A STRING
);

// Set the options for the job
$options = array(
  'return_job_status'=> <true | false>, // Set to true if you want to get the job result in sync (in addition to the result been sent to your callback). If set to false, result is sent to callback url only.
  'return_history' => <true | false>, // Set to true to return results of all jobs you have ran for the user in addition to current job result. You must set return_job_status to true to use this flag.
  'return_image_links' => <true |false>, // Set to true to receive selfie and liveness images you uploaded. You must set return_job_status to true to use this flag.
  'signature' => true
);

// Submit the job.
// This method returns a json array
$response = $connection->submit_job($partner_params, $image_details, $id_info, $options);
?>

Getting the Job Result

By default you always get the result of your job in the callback url you provided, however for some use cases you might want to get the job result in sync after submission. The flag return_job_status can be set to true if you want to get the job result in sync.

Please note that the result you get in sync by setting the return_job_status flag to true might not be the final result if human review is required for the job. We recommend you use the responses sent to your callback to build your business logic as that is where we return the final result

Refer to the category column of result codes of Biometric KYC for the comprehensive list of final codes (approved or rejected) and in-progress codes (inconclusive, provisional approval or suspected for spoof).

Response when return_job_status is set to false

If return_job_status is set to false, the response will be a JSON string containing:

{success: true, smile_job_id: <the generated smile_job_id>}

The job result will be sent to the callback url you provided, it will look as follows:

{
  "Actions": {
      "Liveness_Check": "Passed",
      "Register_Selfie": "Approved",
      "Selfie_Provided": "Passed",
      "Verify_ID_Number": "Verified",
      "Human_Review_Compare": "Passed",
      "Return_Personal_Info": "Returned",
      "Selfie_To_ID_Card_Compare": "Not Applicable",
      "Human_Review_Update_Selfie": "Not Applicable",
      "Human_Review_Liveness_Check": "Passed",
      "Selfie_To_ID_Authority_Compare": "Completed",
      "Update_Registered_Selfie_On_File": "Not Applicable",
      "Selfie_To_Registered_Selfie_Compare": "Not Applicable"
  },

}

Response when return_job_status is set to true

If you have use cases that require you to get the result in sync, you can set the return_job_status to true. We advice that you use the result sent to your callback to make final decisions as there are times when the submitted job requires human review, the final result after the review is completed can not be retrieved by setting the return_job_status to true.

If you set return_job_status to true (with image_links and history also set to true) then you will receive the JSON object containing the machine result like below:

{
   "job_success":true,
   "result":{
      "ConfidenceValue":"99",
