Selivery Enterprise PHP SDK

Official PHP SDK for the Selivery Enterprise API.

Installation

• Require via Composer: composer require selivery/enterprise-sdk-php
• Requires PHP ^8.2 with ext-openssl and ext-json.

Usage

Method: send

send(...) automatically:

• looks up the phone's public key,
• generates a crypto‑random vector (default 32 chars),
• encrypts each secret value using RSA PKCS#1 v1.5 (openssl_public_encrypt) with that vector, and
• includes the resolved key_uuid and the generated vector in the request.

No sender parameter is needed (it is derived from the template on the service).

use Selivery\Enterprise\EnterpriseClient;

$client = new EnterpriseClient(getenv('SELIVERY_SECRET') ?: '');

/** @var Selivery\Enterprise\Models\SendResult $response */
$response = $client->send(
    phone: '+12025550123',
    idTemplate: 1,
    // Vector is generated automatically and used for encryption and request body
    secrets: [
        ['placeholder' => 'code', 'values' => '123456'],
    ]
);

Method: sendLight

Difference from send:

• send encrypts values locally in the SDK and sends only encrypted chunks to Selivery. This means even Selivery (or any intermediary) cannot read your values.
• sendLight accepts plaintext values; Selivery encrypts them as the very first step on the server and then handles only encrypted values afterward. Both methods are secure; send offers an even stricter privacy boundary since plaintext never leaves your process.

/** @var Selivery\Enterprise\Models\SendResult $response */
$response = $client->sendLight(
    phone: '+12025550123',
    idTemplate: 1,
    secrets: [
        ['key' => 'code', 'values' => '123456'],
    ]
);

Token caching (PSR-16)

Inject any PSR-16 cache to enable automatic caching and refresh of OAuth tokens.

use Selivery\Enterprise\EnterpriseClient;
use Symfony\Component\Cache\Adapter\FilesystemAdapter;
use Symfony\Component\Cache\Psr16Cache;

$pool = new FilesystemAdapter(namespace: 'selivery', defaultLifetime: 0);
$psr16 = new Psr16Cache($pool);

// Options (optional):
// - base_url: override API base URL
// - timeout: request timeout in seconds
// - cache_key: override default key (default: selivery_enterprise_sdk_tokens:{sha1(baseUrl)})
// - token_safety_window: seconds before expiry to refresh (default: 60)

$client = new EnterpriseClient(
    secret: getenv('SELIVERY_SECRET') ?: '',
    cache: $psr16,
    options: [
        'token_safety_window' => 60,
        // 'cache_key' => 'custom_key_per_env',
    ]
);

// The SDK generates tokens automatically on the first request,
// then reuses and refreshes them through the cache.

Examples

• Send message: SELIVERY_SECRET=your-secret php examples/service_send.php
• Send light message: SELIVERY_SECRET=your-secret php examples/service_send_light.php

Notes

• EnterpriseClient is the only public entry point. Call send(...) or sendLight(...) on it directly.
• The SDK uses your secret only for generate-token.
• Service requests use the generated access_token automatically.
• If a cache is provided, the SDK stores both access and refresh tokens and refreshes the access token when needed.
• POST endpoints accept JSON bodies; include Content-Type: application/json.
• The sender field has been removed from SDK methods and requests; it is derived from the template server‑side.
• Token cache key default: selivery_enterprise_sdk_tokens:{sha1(baseUrl)}. Avoid putting secrets in cache keys.
• Safety window default: 60s. Treats token as expired when now >= expires_at - safety_window.

PSR-16 implementations

• Symfony Cache: Psr16Cache over FilesystemAdapter (disk) or RedisAdapter (Redis).
• Any PSR-16 provider is supported: pass your Psr\SimpleCache\CacheInterface to EnterpriseClient.

• Symfony filesystem cache: php examples/cache_symfony.php
