> PHP SDK for the [Unitpay.ru](https://unitpay.ru) payment REST API.

A thin, stateless SDK: build a signed redirect to Unitpay's hosted payment page or call the API server-to-server, attach 54-FZ fiscal receipts, and verify inbound webhooks. Everything hangs off one entry point, `Unitpay\Unitpay`, which hands out service objects.

Official Unitpay documentation: [help.unitpay.ru](https://help.unitpay.ru)

> **Upgrading from 3.x?** 4.0 changes the `TransportInterface` contract and starts rejecting webhooks older than 5 minutes. If you use the SDK's own transport and your server clock is synchronised, it is a version bump — see the [v4 Migration Guide](docs/migration-v4.md).
>
> **Upgrading from 2.x?** 3.0 moved every class into the `Unitpay\` namespace and replaced `api('method', [...])` with typed service methods. There is no compatibility shim — see the [v3 Migration Guide](docs/migration-v3.md), then the v4 guide.

Requirements
------------

[](#requirements)

- PHP >= 7.4
- ext-json
- ext-ctype

No Composer dependencies. `ext-curl` is optional: the default transport uses it when present and falls back to `file_get_contents()` otherwise.

Installation
------------

[](#installation)

```
composer require unitpay/php-sdk
```

Then load the Composer autoloader — the package is PSR-4 (`Unitpay\` → `src/`):

```
require __DIR__ . '/vendor/autoload.php';
```

See [Getting Started](docs/getting-started.md) for the `dev-master` option.
