Perform Proof of Address Check

You can run this check immediately via our Demo Postman collection. It's publicly available and doesn't require an account.

Overview of flow

1. Create a client

The first step in creating any check is to create a client from your backend server. For this type of check, a client of type person must be created.

Example request for creating a client

curl -X POST https://api.complycube.com/v1/clients \
     -H 'Authorization: <YOUR_API_KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
          "type": "person",
          "email": "john.doe@example.com",
          "personDetails":{
               "firstName": "John",
               "lastName" :"Doe"
          }
        }'

const { ComplyCube } = require("@complycube/api");

const complycube = new ComplyCube({ apiKey: "<YOUR_API_KEY>" });

const client = await complycube.client.create({
  type: "person",
  email: "john.doe@example.com",
  personDetails: {
    firstName: "John",
    lastName: "Doe"
  }
});

from complycube import ComplyCubeClient
cc_api = ComplyCubeClient(api_key='<YOUR_API_KEY>')

new_client = {
    'type':'person',
    'email':'john.doe@example.com',
    'personDetails': {
        'firstName':'John',
        'lastName':'Doe'
    }
}

client = cc_api.clients.create(**new_client)

use ComplyCube\ComplyCubeClient;

$ccapi = new ComplyCubeClient('<YOUR_API_KEY>');

$result = $ccapi->clients()->create([
    'type' => 'person',
    'email' => 'john.doe@example.com',
    'personDetails' => [
        'firstName' => 'John',
        'lastName' => 'Doe'
    ]
]);

using ComplyCube.Net;
using ComplyCube.Net.Resources.Clients;

var clientApi = new ClientApi(new ComplyCubeClient("<YOUR_API_KEY>"));

var newClient = new ClientRequest {
  type = "person",
  email = "john.doe@example.com",
  personDetails = new PersonDetails {
    firstName = "John",
    lastName = "Doe"
  }
}

var client = await clientApi.CreateAsync(newClient);

Example response

The response will contain an id (the Client ID). It is required for the next step.

{
    "id": "5eb04fcd0f3e360008035eb1",
    "type": "person",
    "email": "john.doe@example.com",
    "personDetails": {

        }'

const document = await complycube.document.create("5eb04fcd0f3e360008035eb1", {
  type: "bank_statement"
});

document = cc_api.documents.create(
    '5eb04fcd0f3e360008035eb1',
    type='bank_statement'
)

$doc = $ccapi->documents()->create(
    '5eb04fcd0f3e360008035eb1',
    ['type' => 'bank_statement']
);

var docRequest = new DocumentRequest {

6. Retrieve outcome

ComplyCube will perform the check. You can retrieve a check's outcome and breakdown via the API.

If you have set up webhooks, a notification is sent upon completion of the check.

Example request for retrieving the check outcome

curl -X GET https://api.complycube.com/v1/checks/5ebd40714f23960008c81527 \
     -H 'Authorization: <YOUR_API_KEY>'

const check = await complycube.check.get("5ebd40714f23960008c81527");

check = cc_api.checks.get('5ebd40714f23960008c81527')

$check = $ccapi->checks()->get('5ebd40714f23960008c81527');
