The Unimatrix PHP SDK provides convenient access to integrate communication capabilities into your PHP applications using the Unimatrix HTTP API. The SDK provides support for sending SMS, 2FA verification, and phone number lookup.

Getting started

Before you begin, you need an Unimatrix account. If you don't have one yet, you can sign up for an Unimatrix account and get free credits to get you started.


Check out the documentation at unimtx.com/docs for a quick overview.


Using Composer is the recommended way to install the Unimatrix SDK for PHP, which is available on Packagist.

Run the following command to add unimtx/uni-sdk as a dependency to your project:

composer require unimtx/uni-sdk


The following example shows how to use the Unimatrix PHP SDK to interact with Unimatrix services.

Initialize a client

use Uni\UniClient;

$client = new UniClient([
  'accessKeyId' => 'your access key id',
  'accessKeySecret' => 'your access key secret'

or you can configure your credentials by environment variables:

export UNIMTX_ACCESS_KEY_ID=your_access_key_id
export UNIMTX_ACCESS_KEY_SECRET=your_access_key_secret

Send SMS

Send a text message to a single recipient.

use Uni\UniClient;
use Uni\UniException;

$client = new UniClient();

try {
  $resp = $client->messages->send([
    'to' => '+1206880xxxx', // in E.164 format
    'text' => 'Your verification code is 2048.'
} catch (UniException $e) {

Send verification code

Send a one-time passcode (OTP) to a recipient. The following example will send a automatically generated verification code to the user.

use Uni\UniClient;
use Uni\UniException;

$client = new UniClient();

$resp = $client->otp->send([
  'to' => '+1206880xxxx'

Check verification code

Verify the one-time passcode (OTP) that a user provided. The following example will check whether the user-provided verification code is correct.

use Uni\UniClient;
use Uni\UniException;

$client = new UniClient();

$resp = $client->otp->verify([
  'to' => '+1206880xxxx',
  'code' => '123456' // the code user provided
