Webservice Client for opilo.com panel

Usage

First, install the opilo/webservice package through Composer PHP dependency manager:

composer require opilo/webservice

Note: if you like to know more about composer, please visit https://getcomposer.org/.

After installing the composer package, in order to send and receive SMS via opilo.com panel, you should create an instance object of class OpiloClient\V2\HttpClient. For that, first you need to configure your webservice in the configuration page.

Create a Client Object

use OpiloClient\V2\HttpClient;
...
$client = new HttpClient('YOUR_WEBSERVICE_USERNAME', 'YOUR_WEBSERVICE_PASSWORD');

Sending SMS

Sending a Single SMS

use OpiloClient\Request\OutgoingSMS;
...
$message = new OutgoingSMS('3000****', '0912*******', 'Hello World!');
$responses = $client->sendSMS($message);

Sending a Batch of SMS at Once

$messages = [
    new OutgoingSMS('3000****', '0912*******', 'Hello World!'),
    new OutgoingSMS('3000****', '0912*******', 'Hello World!'),
];
$response = $client->sendSMS($messages);

User defined ids

In case of network errors, you may resend your SMS to be sure it is delivered to the Opilo server, but you don't want it to be sent to the target more than once. To prevent duplicate SMSes you can set unique strings as uid fields of the OutgoingSMS objects. In case of receiving a SMS with a duplicate uid, the Opilo server drops that SMS and return an SMSId object with a boolean duplicate flag. The duplication of a uid is checked only against the messages sent during the last 24 hours.

$messages = [
    new OutgoingSMS('3000****', '0912*******', 'Dont send this twice!', $some_unique_identifier_for_this_sms),
];

Parsing The Return Value of sendSMS()

use OpiloClient\Response\SMSId;
use OpiloClient\Response\SendError;
...
for ($i = 0; $i < count($response); $i++) {
    if ($response[$i] instanceof SMSId) {
        //store $response[$i]->id as the id of $messages[$i] in your database and schedule for checking status if needed
    } elseif ($response[$i] instanceof SendError) {
        //It could be that you run out of credit, the line number is invalid, or the receiver number is invalid.
        //To find out more examine $response[$i]->error and compare it against constants in SendError class
    }
}

Check the Inbox by Pagination

$minId = 0;
while (true) {
    $inbox = $client->checkInbox($minId);
    $messages = $inbox->getMessages();
    if (count($messages)) {
        foreach ($messages as $message) {
            //Process $message->opiloId(), $message->getFrom(), $message->getTo(), $message->getText(), and $message->getReceivedAt() and store them in your database
            $minId = max($minId, $message->getOpiloId() + 1);
        }
    } else {
        //no new SMS
        //Store $minId in your database for later use of this while loop! You don't need to start from 0 tomorrow!
        break;
    }
}

Checking the Delivery Status of Sent Messages

$opiloIds = $yourDatabaseRepository->getArrayOfOpiloIdsOfMessagesSentViaSendSMSFunction();
$response = $client->checkStatus($opiloIds);
foreach ($response->getStatusArray() as $opiloId => $status) {
    //process and store the status code $status->getCode() for the SMS with Id $opiloId
    //Take a look at constants in OpiloClient\Response\Status class and their meanings
}

Getting Your SMS Credit

$numberOfSMSYouCanSendBeforeNeedToCharge = $client->getCredit()->getSmsPageCount();

Exception Handling

All the functions in HttpClient may throw CommunicationException if the credentials or configurations are invalid, or if there is a network or server error. Prepare to catch the exceptions appropriately.

use OpiloClient\Response\CommunicationException;
...
try {
    ...
    $client->sendSMS(...);
    ...
} catch (CommunicationException $e) {
    //process the exception by comparing $e->getCode() against constants defined in CommunicationException class.
}

Laravel support

To use web service in Laravel, register OpiloClient\Laravel\OpiloServiceProvider in your config/app.php.

    'providers' => [
        // Add this to end of 'providers' array
        OpiloClient\Laravel\OpiloServiceProvider::class,
    ]

You can also add the facade to use web service more conveniently.

    'aliases' => [
        // Add this to end of 'aliases' array
        'Opilo' => OpiloClient\Laravel\HttpClient::class,
    ]

To publish opilo config file, run php artisan vendor:publish --provider="OpiloClient\Laravel\OpiloServiceProvider". Put variables OPILO_WS_USERNAME and OPILO_WS_PASSWORD into your .env file.
