A PHP SDK to make voice calls & send SMS using Plivo and to generate Plivo XML
Frequently asked questions about Plivo Php
- How do I integrate Plivo’s PHP SDK into a Laravel project for sending SMS notifications?
- Install the package via Composer (`composer require plivo/plivo-php`), then configure your Plivo credentials in `.env` (e.g., `PLIVO_AUTH_ID` and `PLIVO_AUTH_TOKEN`). Use the SDK’s `RestClient` class to send SMS by calling `sendMessage()` with sender, recipient, and text parameters. For Laravel, wrap this in a service class or facade to simplify usage across controllers.
- Does this SDK support Laravel’s queue system for handling high-volume SMS or voice calls?
- Yes, the SDK works seamlessly with Laravel queues. Dispatch asynchronous jobs (e.g., `SendSmsJob`) to process messages in the background using Laravel Horizon or database queues. This is ideal for scaling beyond 10,000+ daily messages while avoiding rate limits or timeouts.
- Can I use this SDK for WhatsApp messaging in Laravel, and how do I handle template approvals?
- The SDK supports WhatsApp messaging, but templates must be pre-approved in the Plivo Console. Store approved template IDs in your Laravel config or database, then pass them to the `sendWhatsAppMessage()` method. For compliance, log all WhatsApp interactions and ensure your Laravel app includes user consent workflows.
- What Laravel versions and PHP requirements does `plivo/plivo-php` support?
- The SDK requires PHP 7.3+ and is fully compatible with Laravel 8, 9, and 10. It follows modern PHP practices, so it integrates smoothly with Laravel’s dependency injection, service providers, and facades. Test thoroughly with your Laravel version to ensure no deprecated API usage conflicts.
- How do I generate Plivo XML for IVR call flows directly from Laravel?
- Use the SDK’s `PlivoXml` class to dynamically generate XML for call control (e.g., menus, voice prompts). For example, create a route in Laravel that returns a `PlivoXml` object with `<Speak>`, `<GetDigits>`, or `<Record>` actions. This eliminates the need for external XML files and allows runtime logic.
- Are there alternatives to this SDK if I need to switch communication providers later?
- To mitigate vendor lock-in, abstract the SDK behind a Laravel service interface (e.g., `MessageService`). Implement adapter classes for Plivo and other providers (Twilio, Nexmo) so swapping is as simple as updating a config value. This approach also simplifies testing with mock implementations.
- How do I handle errors and retries for failed SMS or call API requests in Laravel?
- The SDK throws `PlivoRestException` for errors, which you can catch in Laravel’s exception handler or middleware. Implement retry logic using Laravel’s `retry` helper or a package like `spatie/laravel-retryable`. For critical failures, log errors to Sentry or Laravel Telescope and notify admins via email.
- Can I use PHLOs (Plivo’s visual workflows) with this SDK, and how do I manage them in Laravel?
- Yes, the SDK supports PHLOs for complex call flows. Store PHLO UUIDs in your Laravel database or config, then trigger them via `createPHLO()` with the appropriate parameters. Document PHLO logic for non-developers and use Laravel’s job queues to execute PHLOs asynchronously for better performance.
- How do I test the Plivo SDK in Laravel unit tests or feature tests?
- Mock the `RestClient` class in PHPUnit using `createMock()` to test SMS/call logic without hitting Plivo’s API. For feature tests, use Laravel’s HTTP tests to verify endpoints that interact with the SDK. Test edge cases like invalid credentials, rate limits, and WhatsApp template errors.
- What are the best practices for monitoring Plivo API usage and costs in a Laravel app?
- Track API calls and costs by logging responses in Laravel’s `app/Exceptions/Handler.php` or using middleware. Integrate with Plivo’s callback URLs to store delivery receipts in a Laravel model (e.g., `SmsLog`). Use Laravel Scout or a custom table to analyze usage trends, and set budget alerts via Laravel Notifications.
