Vatly API client for PHP

Sell worldwide, today, with Vatly. Dedicated to EU based SAAS merchants and software companies, accept creditcard, PayPal, ApplePay, iDEAL and more.

Using a framework?

This is the raw API client. If you're building a Laravel application, you almost certainly want vatly/vatly-laravel instead — it provides a Cashier-style Billable trait, Eloquent models, a wired webhook endpoint, and event-bus integration on top of this SDK.

Other framework drivers (Symfony, WordPress) are on the roadmap. To build one, see the Driver Author Guide in vatly/vatly-fluent-php.

Installation

You can install the package via composer:

composer require vatly/vatly-api-php

Usage

use Vatly\API\VatlyApiClient;

$vatly = new VatlyApiClient();
$vatly->setApiKey('test_your_api_key_here');

$vatly->checkouts->create([...]);

For detailed documentation, see docs/README.md.

Source of truth. The complete, canonical schema for every request and response — including fields the guides below don't spell out — lives in the OpenAPI spec. If you (or an AI assistant) are unsure whether a field exists or what it's called, check the spec rather than guessing from an example.

Idempotency

The SDK automatically sends an Idempotency-Key header on every POST and PATCH request.

$checkout = $vatly->checkouts->create([
    'products' => [
        ['id' => 'subscription_plan_abc123', 'quantity' => 1],
    ],
    'redirectUrlSuccess' => 'https://yourapp.com/success',
    'redirectUrlCanceled' => 'https://yourapp.com/canceled',
]);

To set a custom key for the next mutating request, use setIdempotencyKey(). The manual key is cleared after the request is sent.

$vatly->setIdempotencyKey('checkout-create-123');

$checkout = $vatly->checkouts->create([
    'products' => [
        ['id' => 'subscription_plan_abc123', 'quantity' => 1],
    ],
    'redirectUrlSuccess' => 'https://yourapp.com/success',
    'redirectUrlCanceled' => 'https://yourapp.com/canceled',
]);

Some endpoint methods also accept a per-request idempotencyKey option:

$checkout = $vatly->checkouts->create([...], [
    'idempotencyKey' => 'checkout-create-123',
]);

$subscription = $vatly->subscriptions->update('subscription_123', [
    'quantity' => 2,
], [
    'idempotencyKey' => 'subscription-update-123',
]);

You can replace or disable the automatic generator when needed:

$vatly->setIdempotencyKeyGenerator(new MyIdempotencyKeyGenerator());
$vatly->clearIdempotencyKeyGenerator();

Webhooks

Verify and parse incoming Vatly webhooks with Webhook::parse(), which returns a typed WebhookPayload:

use Vatly\API\Webhooks\Webhook;

$event = Webhook::parse($rawBody, $signatureHeader, $webhookSecret);

For strongly-typed, per-event objects, this package also owns immutable event DTOs under Vatly\API\Webhooks\Events\* (e.g. OrderPaid, RefundCompleted, SubscriptionStarted). Money fields are Vatly\API\Types\Money (decimal-string + currency; call $event->total->toCents() / read $event->total->currency to flatten at your persistence edge) and the VAT breakdown is Vatly\API\Types\TaxSummaryCollection; order lines are Vatly\API\Types\OrderLineData. These are the canonical event shapes that higher-level integrations build on.

Vatly\API\Webhooks\WebhookEventFactory turns a verified payload into one of these typed events — verify, parse, and map all happen in api-php now. Pass it a VatlyApiClient and hand it the WebhookReceived from fromPayload():

use Vatly\API\Webhooks\Webhook;
use Vatly\API\Webhooks\WebhookEventFactory;

$payload = Webhook::parse($rawBody, $signatureHeader, $webhookSecret);

$factory = new WebhookEventFactory($client);
$event = $factory->createFromWebhook($factory->fromPayload($payload));
// e.g. $event instanceof Vatly\API\Webhooks\Events\OrderPaid

Because Vatly sends fat, HMAC-signed payloads — the delivery's object is byte-identical to the corresponding GET /…/{id} body — the factory builds every event straight from the signed payload (hydrating the matching api-php resource in memory for money/tax-bearing events). It makes no follow-up API call. Use getSupportedEvents() / isSupported() to inspect the event surface.

The incoming webhook payloads are described in the webhooks: section of the OpenAPI spec. See docs/Webhooks.md for the full guide.
