# Check-Driven Integration

## Overview

This guide walks you through integrating the Hosted Solution with ComplyCube using the check-driven approach, giving you direct control over individual verification steps.

You’re viewing the **check-driven** SDK guide - an approach that provides detailed control but is best suited for **partners** or **advanced use cases.**  We recommend using **workflow integration** for most implementations.

ComplyCube's Hosted Solution requires a **Hosted Solution session** to be initiated by your backend. Here’s how it works:

{% stepper %}
{% step %}

#### **Create a client**

Every Hosted Solution session starts with a **client** (i.e. customer). Use the API to [create the client](/documentation/api-reference/core-resources/clients/create-a-client.md).

**Example request**

{% tabs %}
{% tab title="cURL" %}

```bash
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"
          }
        }'
```

{% endtab %}

{% tab title="Node.js" %}

```javascript
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"
  }
});
```

{% endtab %}

{% tab title="Python" %}

```python
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)
```

{% endtab %}

{% tab title="PHP" %}

```php
use ComplyCube\ComplyCubeClient;

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

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

{% endtab %}

{% tab title=".NET" %}

```csharp
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.com",
  personDetails = new PersonDetails {
    firstName = "John",
    lastName = "Doe"
  }
}

var client = await clientApi.CreateAsync(newClient);
```

{% endtab %}
{% endtabs %}

**Example response**

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

```json
{
    "id": "5eb04fcd0f3e360008035eb1",
    "type": "person",
    "email": "john.doe@example.com",
    "personDetails": {
        "firstName": "John",
        "lastName": "Doe",
    },
    "createdAt": "2020-01-04T17:24:29.146Z",
    "updatedAt": "2020-01-04T17:24:29.146Z"
}
```

{% endhint %}
{% endstep %}

{% step %}

#### Generate a Hosted Solution session

A **Hosted Solution session** creates a unique ComplyCube URL that you can use to redirect your customers to complete their identity verification. Once complete, your clients will be redirected to your chosen URL.

**Example request**

{% tabs %}
{% tab title="cURL" %}

```bash
curl -X POST https://api.complycube.com/v1/flow/sessions \
     -H 'Authorization: <YOUR_API_KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
          "clientId":"CLIENT_ID",
          "checkTypes": ["extensive_screening_check", "identity_check", "document_check"],
          "successUrl": "https://www.yoursite.com/success",
          "cancelUrl": "https://www.yoursite.com/cancel"
        }'
```

{% endtab %}

{% tab title="Node.js" %}

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

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

const session = await complycube.flow.createSession("CLIENT_ID", {
    checkTypes: [
      "extensive_screening_check",
      "identity_check",
      "document_check"
    ],
    successUrl: "https://www.yoursite.com/success",
    cancelUrl: "https://www.yoursite.com/cancel",
    theme: "light"
});
```

{% endtab %}

{% tab title="Python" %}

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

flow_session = {
    'clientId': client.id,
    'checkTypes':[
        'extensive_screening_check',
        'identity_check',
        'document_check'
    ],
    'successUrl':'https://www.yoursite.com/success',
    'cancelUrl':'https://www.yoursite.com/cancel',
    'theme': 'light'
}

session = cc_api.flow.create(**flow_session)
```

{% endtab %}

{% tab title="PHP" %}

```php
use ComplyCube\ComplyCubeClient;

$ccapi = new ComplyCubeClient('<YOUR_API_KEY>');
$session = $ccapi->flow()->createSession([
    'clientId' => $clientId,
    'checkTypes' => [
        'extensive_screening_check',
        'identity_check',
        'document_check'
    ],
    'successUrl' => 'https://www.yoursite.com/success',
    'cancelUrl' => 'https://www.yoursite.com/cancel',
    'theme' => 'light'
]);
```

{% endtab %}

{% tab title=".NET" %}

```csharp
using ComplyCube.Net;
using ComplyCube.Net.Resources.FlowSessions;

var fSession = new FlowSessionApi(new ComplyCubeClient("<YOUR_API_KEY>"));

var flowSession = new FlowSessionRequest {
  clientId = aClient.id,
  checkTypes = new string[] {
    "extensive_screening_check",
    "identity_check",
    "document_check"
  },
  successUrl = "http://complycube.com",
  cancelUrl = "http://complycube.com"
};

var result = fSession.CreateAsync(flowSession).Result;
```

{% endtab %}
{% endtabs %}

**Example response**

{% code overflow="wrap" %}

```json
{
    "redirectUrl": "https://flow.complycube.com/test_ODdkNjhiOTU0MzY4YmE5NjRmMDMyY2E5MWYwZjgxNjMzZTcyMWJmNzU2YjZmNDQ4NmFjMTU0ZGZhYTU5MmNhY2NiNjI3ZDE4YWJkYmU2M2M3ZWYzZTlmM2M3MzgxMmM3NzZhMjVlYmQyNDI0ODdkOWQ3M2JiMjkxZTYxNzdhYmExMGEzOGRhYmM2OTIwMjgyYmEzZGY3ZDY0NWZhMjcwN2RlMTFkOTcxZWNhOWI2Zjg0NjllZGNkODVjYzMzMDA5YjdlMWY5OGIwMmZjY2UzNGI2YTMxOGQxNGZmNGFhYjczNzU0YmYwMjFkMzU1M2FjMjQ4ZDQ2ZjJjZTY4YWY0MzIxNjVlMDRjOTIyYTExMTlmMWU3YTYwMDY1NGJmYWM0NTA2MDE5NTg5NTkxYzA4MzYyYTUyM2I0NDM4OGExNWIyMTIzYTBhNDc0NDA4NWM2ZTQwMmNjMGVjMTk2YW"
}
```

{% endcode %}

{% hint style="info" %}
See [Flow Sessions API Reference](/documentation/api-reference/other-resources/tokens.md) to learn more.
{% endhint %}
{% endstep %}

{% step %}

#### Redirect the client to the URL

Redirect your client to the `redirectUrl` generated in the previous step. Once the customer completes the flow on the hosted solution:

1. ComplyCube will automatically run the checks you selected when creating the session (as specified in `checkTypes`).
2. The customer will be redirected to the `successUrl` you provided.

You can access the results and a detailed breakdown of each check via the API or Web Portal. If you’ve **configured webhooks**, ComplyCube will send a notification upon completion of each check.
{% endstep %}
{% endstepper %}

## Branding

You can customize accent colors and upload your logos to the hosted page via the [brand settings page](https://portal.complycube.com/settings/branding), if available on your plan.
