Install Twilio PHP SDK
- First, you'll need to ensure that the Twilio PHP SDK is installed. This library will make it easier to interact with the Twilio API. You can add it to your project via Composer.
composer require twilio/sdk
Initialize Twilio Client
- To send a fax, you need to create an instance of Twilio's REST Client. This client will handle the authentication and communication with Twilio's services. Use your account SID and Auth Token for this step.
require 'vendor/autoload.php';
use Twilio\Rest\Client;
$sid = 'YOUR_ACCOUNT_SID';
$token = 'YOUR_AUTH_TOKEN';
$twilio = new Client($sid, $token);
Send a Fax
- You are now ready to send a fax. Use the fax endpoint provided by the Twilio API to send a fax to a specified recipient. You need the Twilio phone number you are sending the fax from, the recipient's fax number, and the URL of the document to be sent.
try {
$fax = $twilio->fax->v1->faxes
->create("recipient_fax_number", // where to send the fax
"twilio_phone_number", // Twilio number
array(
"mediaUrl" => "http://www.example.com/document.pdf"
)
);
echo "Fax sent with SID: " . $fax->sid;
} catch (Exception $e) {
echo "Error: " . $e->getMessage();
}
Handle Response and Errors
- Once the request to send a fax is made, you will receive a response containing details about the fax. It's crucial to handle any exceptions that may occur during the operation to ensure your application doesn't crash. Use try-catch blocks in PHP to catch and manage exceptions accordingly.
try {
// Sending fax code...
} catch (\Twilio\Exceptions\RestException $e) {
echo "Twilio Exception: " . $e->getMessage();
} catch (Exception $e) {
echo "General Exception: " . $e->getMessage();
}
Monitor Fax Status
- Twilio allows you to track the status of your fax. You can make a request to fetch fax details based on the Fax SID returned when the fax was created. This information will enable you to handle retries or any additional logic based on delivery status.
try {
$faxSid = 'your_fax_sid_here';
$fax = $twilio->fax->v1->faxes($faxSid)->fetch();
echo "Fax Status: " . $fax->status;
} catch (Exception $e) {
echo "Error fetching fax details: " . $e->getMessage();
}
Secure Sensitive Information
- Never hard-code your Twilio credentials or sensitive data in your source code. Use environment variables or a secure vault to store this information. By doing this, you mitigate the risk of exposing your credentials in version control or production logs.
