Full ID Verification

Introduction

The Full ID Verification API allows you to perform identity verification using a document and a selfie image. This API provides valuable information extracted from the provided images, including personal details and biometric data.

Authentication

To use the Full ID Verification API, you need to authenticate your requests by including your API credentials (app-id and app-key) in the HTTP headers.

STEP 1 : Get UUID

Submit a verification request by providing a document image and a selfie image. The API will process these images and provide you with a Unique Identifier (UUID) for tracking and retrieving the results.

  • URL: https://idv-eu.kairos.com/v0.1/full-id-verification

  • Method: POST

  • Headers:

    • Content-Type: multipart/form-data

    • app-id: Your API application ID.

    • app-key: Your API application key.

  • Body:

    • selfie: The selfie image for comparison.

    • document: The document front image to be verified.

    • document_back: The document back image to be verified.

Example Request:

import requests

url = "https://idv-eu.kairos.com/v0.1/full-id-verification"
files=[
    ('selfie',('file',open('/path/to/selfie_image','rb'))),
    ('document',('file',open('/path/to/document_image','rb'))),
    ('document_back',('file',open('/path/to/document_back_image','rb')))
]
headers = {
    'app_id': '811ed7d1',
    'app_key': '45e4f0a37851a6257f54a8d715a38d98'
}
response = requests.request("POST", url, headers=headers, files=files)

Response

The API response for this step will include a UUID (Unique Identifier) that you will use in the next step to fetch the verification results.

{"api_req_uuid":"fca044bd-a6a7-4a4a-bc11-ecd012ec7af3"}

STEP 2 : Get Verification Results

Once you have obtained the UUID from the initial request, you can use it to retrieve the verification results in JSON format.

  • URL: https://idv-eu.kairos.com/v0.1/full-id-verification/{uuid} (Replace {uuid} with the actual UUID obtained in Step 1)

  • Method: GET

  • Headers:

    • Content-Type: application/json

    • app-id: Your API application ID.

    • app-key: Your API application key.

Example Request

import requests

api_req_uuid = 'fca044bd-a6a7-4a4a-bc11-ecd012ec7af3'
url = f"https://idv-eu.kairos.com/v0.1/full-id-verification/{api_req_uuid}"

headers = {
    'app_id': '811ed7d1',
    'app_key': '45e4f0a37851a6257f54a8d715a38d98'
}

response = requests.request("GET", url, headers=headers)

Response

The API response for this step will contain detailed verification results in JSON format, including decision information, biometric data, and verification data.
