PHP

The esmsafrica/sms package is a PSR-4 library with no framework dependency. Requires PHP 7.4+ with the curl and json extensions.

Install

composer require esmsafrica/sms

Quickstart

send.php

<?php
require 'vendor/autoload.php';

$esms = new \Esms\Client('esms_live_...');

$res = $esms->messages->send([
    'to'        => '+256700000000',
    'text'      => 'Your verification code is 123456',
    'sender_id' => 'eSMSAfrica', // optional — falls back to the route default
]);

echo $res['id'], ' ', $res['status']; // "...", "submitted"

Get an API key in the dashboard under Developers → API Keys. Responses are associative arrays that mirror the API JSON.

Sending

// Auto-detects the route (country) from the number.
$esms->messages->send(['to' => '+254711000000', 'text' => 'Hi from Kenya']);

// Or pin a route explicitly.
$esms->messages->send(['to' => '+256700000000', 'text' => 'Hi', 'route' => 'ESMS_UG']);

// Schedule for later (5 minutes to 7 days out).
$esms->messages->schedule([
    'to'           => '+256700000000',
    'text'         => 'Reminder',
    'scheduled_at' => new DateTime('+1 hour'), // or an ISO-8601 string
]);

Delivery status

$msg = $esms->messages->get($res['id']);
echo $msg['status']; // queued | submitted | delivered | failed | ...
foreach ($msg['timeline'] as $event) {
    echo $event['at'], ' ', $event['event'], PHP_EOL;
}

// List recent messages
$page = $esms->messages->list(0, 20, 'delivered');
echo $page['total'];

// Retry a failed one
$esms->messages->retry($res['id']);

Balance & routes

$bal = $esms->balance->get();
echo "{$bal['currency']} {$bal['balance']}";

foreach ($esms->routes->list() as $r) {
    echo $r['code'], ' ', $r['country_name'], PHP_EOL;
}

Error handling

Every failure is an \Esms\Exception\EsmsException. Catch specific subclasses to branch:

use Esms\Exception\InsufficientBalanceException;
use Esms\Exception\AuthenticationException;
use Esms\Exception\EsmsException;

try {
    $esms->messages->send(['to' => '+256700000000', 'text' => 'Hi']);
} catch (InsufficientBalanceException $e) {
    echo "Top up: have {$e->getBalance()}, need {$e->getCost()} {$e->getCurrency()}";
} catch (AuthenticationException $e) {
    echo "Check your API key.";
} catch (EsmsException $e) {
    echo $e->getStatus(), ' ', $e->getApiCode(), ': ', $e->getMessage();
}

`AuthenticationException`	401 — key missing or invalid
