​
Overview

Generate a one-time password (OTP) code and automatically send it to a WhatsApp user. This endpoint is perfect for implementing two-factor authentication, phone verification, or secure login systems.

​
How It Works

  1. Send a request with the recipient’s chatId and OTP configuration
  2. The system generates a random code based on your specifications
  3. The code is stored with an expiration time
  4. A message containing the code is queued to be sent to the user
  5. You receive the code details to verify later

​
Parameters

​
chatId (required)

The WhatsApp chat ID of the recipient (e.g., [email protected])

​
length

The length of the OTP code. Default is 6 characters.

​
useLetter

Include letters in the code generation. Default is false.

​
useNumber

Include numbers in the code generation. Default is true.

​
allCapital

Make all letters uppercase when useLetter is true. Default is false.

​
name

The name to display in the message template (e.g., your app or service name).

​
expires

Time-to-live (TTL) in seconds before the code expires. Default is 1800 seconds (30 minutes).

​
Response

The response includes:
  • uuid: Unique identifier for this OTP request
  • chat_id: The recipient’s chat ID
  • code: The generated OTP code (store this securely if needed)
  • status: Current status (pending, sent, validated, or expired)
  • otp_type: Type of OTP (always code for this endpoint)
  • expires_at: ISO 8601 timestamp when the code expires
  • created_at: ISO 8601 timestamp when the code was created

Request OTP Code

​
Usage Example

use Illuminate\Support\Facades\Http;

$response = Http::withToken('YOUR_API_TOKEN')
    ->post('https://app.hypersender.com/api/otp/v2/{instance}/request-code', [
        'chatId' => '[email protected]',
        'length' => 6,
        'useLetter' => false,
        'useNumber' => true,
        'name' => 'YourAppName',
        'expires' => 1800,
    ]);

$result = $response->json();
$otpData = $result['data'] ?? null;

// Example: log or store uuid and status
info('OTP uuid: ' . ($otpData['uuid'] ?? ''));

​
Next Steps

After generating the code:
  1. The user will receive the OTP via WhatsApp
  2. User enters the code in your application
  3. Use the Validate OTP Code endpoint to verify the code
  4. Check the uuid to track the verification status
Set an appropriate expires time based on your security requirements. Shorter expiration times (5-10 minutes) provide better security but may frustrate users if they need more time to complete the verification.
