Generate OTP Link - Hypersender

Create a passwordless flow: generate a WhatsApp link that pre-fills a message with a unique code. When the user taps Send in WhatsApp, you get the verification event via callbacks. Use the Laravel SDK method to keep things concise.

Parameters

Field	Type	Required	Description
expires	int	no	TTL in seconds (default `1800`).
name	string	no	Your app name displayed in messages.
message.prompt	string	yes	Text pre-filled in the WhatsApp link.
message.success	string	yes	Reply when verification succeeds. Use `{link}` placeholder.
message.failed	string	yes	Reply when verification fails.
message.expired	string	yes	Reply when the link expired.
callback.success	string	no	Webhook URL for successful verification.
callback.failed	string	no	Webhook URL for failed verification.

Generate the link

use Hypersender\Hypersender;

$response = Hypersender::otp()->generateLink([
  'expires' => 900,
  'name' => 'YourApp',
  'message' => [
    'prompt' => 'Give me link to login at YourApp',
    'success' => 'Welcome! Here is your login link: {link}',
    'failed' => 'Login failed. Please try again.',
    'expired' => 'This link expired. Request a new one.',
  ],
  'callback' => [
    'success' => 'https://yourdomain.com/api/otp/success',
    'failed' => 'https://yourdomain.com/api/otp/failed',
  ],
]);

$whatsappLink = $response['whatsapp_link'] ?? null;

Send whatsappLink via email, SMS, or in-app notification. When the user clicks it, WhatsApp opens with the prompt + code. Handle callbacks to finalize the login.

Secure your callback endpoints (HTTPS + auth) and invalidate links after use.
