Installation

The packages is available on Packagist and can be installed via Composer by executing following command in shell.

composer require craftsys/msg91-php

Usage

If you're using Composer, make sure the autoloader is included in your project's bootstrap file:

require_once "vendor/autoload.php";

Now the client can be initialised by passing a configured object to the constructor.

$config = [
  'key' => "123456789012345678901234",
];
$client = new Craftsys\Msg91\Client($config);

The package in distributed under Craftsys\Msg91 namespace which can used if your are working in a namespace environment.

<?php
// in your use statement sections
use Craftsys\Msg91\Client;

// somewhere in this source file where you need the client
$client = new Client($config);

// send OTP using the otp service on client
$client->otp()->to(919999999999)->send();

// verify an OTP (1234)
$client->otp(1234)->to(919999999999)->verify();

// send SMS using the sms service on client
$client->sms()->to(919999999999)->flow("<flow_id>")->send();

Continue reading to learn more about configuration and available method on opt and sms services with examples.

Create a Client

The client is responsible for interacting with Msg91 apis.

$client =  new Craftsys\Msg91\Client($config);

Client can also be initialised without a configuration which can be set by calling setConfig($config) method on the client instance.

$client =  new Craftsys\Msg91\Client();
$client->setConfig($config);

You can also pass a custom GuzzleHttp\Client as the second argument on the Client's constructor.

$client = new Craftsys\Msg91\Client($config, new GuzzleHttp\Client());

Configuration

The module is configurable to your specific needs where you need to set default options for APIs like the default OTP message format, retry method etc.

An example configuration might look something like this:

$config = [
	'key' => "123456789012345678901234",
	'otp_message' => "G: ##OTP## is your verification code".
];

Following configuration options are available:

NOTE: Setting any if these values as null will override the default values to null too. And so, the default values from Msg91 APIs will be used. For example, setting the otp_message to null will let use "Your verification code is ##OTP##" which the default from APIS

OTP and SMS Services

After a client has been created, you can access otp and sms services to send OTPs and SMSs respectivily.

NOTE: Configuration must be set before using any other services on the client.

// send otp
$client->otp()->to(919999999999)->send()

// verify a given otp
$client->otp(<otp_to_be_verified>)->to(919999999999)->verify()

// resend otp via voice channel
$client->otp()->to(919999999999)->viaVoice()->resend()

// send sms
$client->sms()->to(919999999999)->flow("<flow_id>")->send();

Next, follow along with examples to learn more

Examples

Managing OTPs

OTP services like sending, verifying, and resending etc, can be accessed via otp method on the client instance e.g. $client->otp(). All the parameters which are available for the Msg91 API, have a corresponding intuitive method name e.g. to set the digits in otp for the send OTP request, you call the digits method on the service. You can create there via \Craftsys\Msg91\Options class. See following examples to learn more.

Send OTP

Basic Usage

$otp = $client->otp();
// an OTP (optional) can be passed to service if you are generating otp on your end
// $otp = $client->otp(4657);

$otp->to(912343434312) // phone number with country code
	->send(); // send the otp

Advanced Usage

Instead of relying on defaults from the Msg91 or the client, you can pass all the custom options that are accepted by Msg91 APIs using the options helper on the service. This method accepts a close which will be called with underline \Craftsys\Msg91\OTP\Options instance and gives your the full flexibility to add any options that is required.

$otp->to(91123123123)
    ->from("SENDER_ID") // sender id
    ->template("AFH") // template id for otps
    ->options(function (\Craftsys\Msg91\OTP\Options $options) {
        $options->digits(6) // set the number of digits in generated otp
          ->message("##OTP## is your verification code") // custom template
          ->expiresInMinutes(60); // set the expiry
    })
	->send() // finally send

NOTE: If you are generating the OTP at your side, and passing it to the service, along with a custom message, you MUST include the ##OTP## or actual value of OTP inside the message. Failing to do so will result in error

// OK
$client->otp(123242)->message('Your OTP is: 123242')->send();

// NOT OK!
$client->otp(123123)->message("Use this for verification")->send();
// This will result in error with "Message doesn't contain otp"

Verify OTP

As the verification does not send any messages, you just need to provide the required fields to verify the OTP e.g. the sent OTP and Phone Number only.

$otp = $client->otp(12345);  // OTP to be verified

$otp->to(912343434312) // phone number with country code
	->verify(); // Verify

Resend OTP

To resend an OTP, access to otp service and call the resend with to resend the OTP. Method of communication can be changed by calling viaVoice or viaText before sending the OTP. The default values can be set into the configuration

$otp = $client->otp();

$otp->to(912343434312) // set the mobile with country code
	->viaText() // or ->viaVoice()
	->resend(); // resend otp

Sending SMS

To send SMS, access the SMSService by calling ->sms() method on the client instance

$sms = $client->sms();

$sms->to(912343434312) // set the mobile with country code
    ->flow('flow_id_here') // set the flow id
	->message("You have 10 pending tasks for the end of the day") // message content
	->send(); // send the message

To add any more options to the message, you can call the options method before sending the message. The options method accepts a call which will receive a \Craftsys\Msg91\SMS\Options instance. Using it, you can modify any desired option.

$client->sms()
    ->to(919999999999)
    ->flow('flow_id_here') // set the flow id
    ->options(function ($options) {
        $options->transactional() // set that it is a transactional message
            ->from('CMPNY') // set the sender
            ->unicode(); // handle unicode as the message contains unicode characters
    })
    ->message("I ❤️ this package. Thanks.")
    ->send();

Message Variables

To send SMS, you create Flow where you can provide a template for your SMS. This template may contain some variables which you use as placeholder for per message data. You can use recipients method to set the values for these variables per recipient while sending SMS as follows.

Let's assume that you have create a Flow with following message template

Hi ##name##, Your reward credits will expire on ##date##.
Claim them to get exclusive benefits

We will to update the name and date variables per recipient.

$client->sms()
    ->flow('flow_id_here') // set the flow id
    ->recipients([
        ['mobiles' => '919999999999', 'name' => 'Sudhir M', 'date' => '20 Jan, 2022'],
        ['mobiles' => '919898912312', 'name' => 'Craft Sys', 'date' => '25 Jan, 2022']
    ])
    ->options(function ($options) {
        $options->receiverKey('mobiles'); // set your receiver key
    })
    ->send();

The mobiles key in the recipients array comes from the receiver field's value which we set when creating a new Flow. It defaults to mobiles. If you have provided a different receiver key, please update the recipients key accordingly.

If you want to put same value for a variable for all recipients, you can use variable method as follows

$client->sms()
    ->flow('flow_id_here') // set the flow id
    ->to([919898912312, 912343434312]) // you can pass an array of mobile numbers
    ->variable('overdue', 'Yes') // set the "overdue" variable's value to "Yes"
    ->variable('url', 'https://domain.com') // set the "url" variable's value to "https://domain.com"
    ->send();

// you can also combine this with existing variables if you want e.g.
$client->sms()
    ->flow('flow_id_here') // set the flow id
    ->recipients([
        ['mobiles' => '919999999999', 'name' => 'Sudhir M', 'date' => '20 Jan, 2022'],
        ['mobiles' => '919898912312', 'name' => 'Craft Sys', 'date' => '25 Jan, 2022']
    ])
    ->variable('overdue', 'Yes') // will set the "overdue" for all recipients
    ->send();

Note: You should call the variable method only after you have set the recipients.

Receiver Key

When creating a Flow on MSG91, you can create a custom receiver key which default to ##mobiles##. This default is being used in this package as well. If you have configured your flow with a different receiver key, you can set it via receiverKey method as follows:

Assuming you have set the receiver field to ##contact##,

$client->sms()
    ->to(919999999999)
    ->flow('flow_id_here') // set the flow id
    ->options(function ($options) {
        $options->receiverKey('contact'); // your receiver key
    })
    ->send();

Handling Responses

All the services will return \Craftsys\Msg91\Support\Response instance for all successfully responses and will throw exceptions if

\Craftsys\Msg91\Exceptions\ValidationException: request validation failed
\Craftsys\Msg91\Exceptions\ResponseErrorException: there was an error in the response

try {
    $response = $client->otp()->to(919999999999)->send();
    // response data
    // $response->getData();
    // response message
    // $response->getMessage();
    // response status code
    // $response->getStatusCode();
} catch (\Craftsys\Msg91\Exceptions\ValidationException $e) {
    // issue with the request e.g. token not provided
} catch (\Craftsys\Msg91\Exceptions\ResponseErrorException $e) {
    // error thrown by msg91 apis or by http client
} catch (\Exception $e) {
    // something else went wrong
    // please report if this happens :)
}
