# How to use

### Method 1: No Code - Creating Verification Through Workplace

1. **Navigate to the Applicants Page:**
   * Go to the "Verification" section and then select "Applicants."
2. **Create a New Verification:**
   * Fill in the required details:
     * **Application:** Choose the relevant application.
     * **Flow:** Select the desired flow.
     * **ExternalUserId:** Provide the external user ID (unique userID from your system).
     * **Language:** Set the preferred language (e.g., `lang`).
     * **Token Lifetime:** Specify the token lifetime.
3. **Generate Verification Link:**
   * After providing the necessary information, our system will generate a link.
   * Share this link with the user to grant them access to the verification process.

### Method 2: Automated - Creating Verification Through SDK

To automate the verification process, you can use our SDK. This method involves generating a token on your backend and initializing the SDK with the token as a parameter.

#### Steps for Automated Verification

1. **Create a Token:**
   * Generate a token on your backend. This step should be done securely to ensure the integrity and security of the verification process. More details can find in [Open API](/home/integration/open-api.md) section

```javascript
const axios = require('axios');

async function createToken() {
    const response = await axios.post('https://billing.elkyc.com/api/public/verification', {
        flowName: 'yourFlowName',
        externalUserId: 'user123',
        ttl: 3600,
        locale: 'uk'
    }, {
        headers: {
            'x-private-app-key': 'yourPrivateAppKey'
        }
    });
    return response.data.accessToken;
}
```

1. [**Initialize the SDK**](/home/integration/usage.md)**:**
   * Use the generated token to initialize the SDK.
   * Pass the token as a parameter when setting up the SDK.

### Private Application Key

In order to use the public api you will need to obtain a private key.

You can retrieve your **Private Application Key** from `Applications > Private app key`.
