PHP SDK
Build video on FastPix from PHP: a php video SDK
The official FastPix SDK for PHP. Typed end-to-end, async-aware, retry-safe. Encodes a source URL into a playback ID in one call, provisions LL-HLS live streams, verifies webhooks with one helper, and ships with a migration path from the closest API peer (see comparison).
Trusted by product teams shipping video at scale







Install
One install, one client, one call
Add the package, point the client at your API key, and you're talking to FastPix — strongly-typed, no scaffolding.
Install the package
bash · terminal
composer require fastpix/fastpix-phpRuntime
PHP 8.1+, Laravel 10+ / Symfony 6.4+.
Type safety
PHP 8.1+ enums, readonly classes, typed properties everywhere.
IDE support
PhpStorm, VS Code with Intelephense, full type inference.
Initialize the client
PHP · app.php
use FastPix\Client;
$fp = new Client(apiKey: $_ENV['FASTPIX_API_KEY']);Common operations
From upload to playback in 4 calls
Encode, wait, stream, upload. The four most common flows, typed end-to-end.
1. Encode a source URL into a playback ID
$asset = $fp->assets->create(
inputs: [['url' => 'https://your-cdn.com/source.mp4']],
playbackPolicy: PlaybackPolicy::Public,
);
echo $asset->playbackId; // "abc123"2. Wait until the asset is ready
// Poll until the asset is ready, or listen for the asset.ready webhook.
$ready = $fp->assets->waitUntilReady(
$asset->id,
pollIntervalSeconds: 2,
timeoutSeconds: 300,
);3. Provision a low-latency live stream
$stream = $fp->live->create(
latencyMode: LatencyMode::Low, // LL-HLS
reconnectWindowSeconds: 60,
playbackPolicy: PlaybackPolicy::Public,
);
// $stream->streamKey -> push to rtmp://global-live.fastpix.com/live4. Resumable chunked upload
// Resumable chunked upload from a PHP CLI worker
use FastPix\Upload\ChunkedUpload;
ChunkedUpload::fromPath(
endpoint: $assetUploadUrl,
path: __DIR__ . '/source.mp4',
chunkSizeMb: 8,
onProgress: fn(int $pct) => echo "{$pct}%\n",
)->run();Security, compliance, and partnerships
Webhook signature verification
One helper, every event typed
Every webhook FastPix sends is signed. The SDK verifies the signature and returns a fully-typed event payload. Switch on event.type and reach the typed payload directly.
use FastPix\Webhooks;
// Laravel route example
Route::post('/webhooks/fastpix', function (Request $request) {
$event = Webhooks::verify(
payload: $request->getContent(),
signature: $request->header('FastPix-Signature'),
secret: env('FASTPIX_WEBHOOK_SECRET'),
);
match ($event->type) {
'asset.ready' => /* $event->data is fully typed */ null,
default => null,
};
return response()->noContent();
});Concurrency model
Built for the PHP runtime
Single-request-per-process by default (the PHP-FPM model). For Laravel Octane and Swoole, the Client can be safely shared as a long-lived singleton; per-request state is local to each request handler. PSR-18 HTTP client is pluggable.
Type safety + IDE support
PHP 8.1+ readonly classes and enums are used throughout. Webhook event payloads are tagged unions via the type property and a typed data property. PHPStan and Psalm level 8 clean out of the box.
Migration
Swap the client, keep the shape
FastPix exposes primitives that mirror the closest API peer. The PHP SDK keeps the call shapes recognizable so the migration is a one-file swap, not a rewrite. FastPix vs Mux side-by-side.
// Before: use MuxPhp\Api\AssetsApi;
// FastPix:
use FastPix\Client;
$fp = new Client(apiKey: $_ENV['FASTPIX_API_KEY']);
// Before: $result = $assetsApi->createAsset($createAssetRequest);
// FastPix:
$asset = $fp->assets->create(
inputs: [['url' => $url]],
playbackPolicy: PlaybackPolicy::Public,
);
// Before: $result->getData()->getPlaybackIds()[0]->getId();
// FastPix:
$asset->playbackId;Bulk migration tooling at /compare/mux and the docs migration guide handles asset re-ingest and playback-ID remap.
FAQ
PHP SDK FAQ
What does the PHP SDK ship with out of the box?
All API surfaces (assets, live streams, playback policies, webhooks, simulcast, analytics query) plus the resumable chunked upload helper, webhook signature verification, automatic retries with exponential backoff, and configurable timeout / base URL / HTTP client. Type definitions are bundled.Is the PHP SDK production-ready?
Yes. The client is used in production by FastPix customers shipping video on the PHP runtime. The retry policy, connection pool defaults, and timeout shape are tuned against the same workload patterns that produce the numbers on the /performance page.How do I authenticate against the FastPix API from PHP?
Set the FASTPIX_API_KEY environment variable and pass it to the client constructor. The SDK adds the Bearer header on every request. For server-side runtimes, fetching the API key from your secret store at startup and constructing the client once at module load is the recommended pattern.Where do I get an API key?
Sign up at the FastPix dashboard. The free trial provisions a key with no credit card; the trial plan covers 10 videos plus 100K streaming minutes plus AI samples. See /pricing for the full plan structure.
