PHP versions
------------

[](#php-versions)

PHP version 7.4 and above is supported.

Documentation
-------------

[](#documentation)

This library supports two Coinbase APIs:

Commerce API (Legacy)Payment Link API (New)**Auth**`X-CC-Api-Key` headerJWT Bearer token (ES256)**Base URL**`api.commerce.coinbase.com``business.coinbase.com/api/v1`**Currency**Multiple cryptocurrenciesUSDC only**Resources**Checkout, Charge, Invoice, EventPaymentLink**Namespace**`CoinbaseCommerce\``CoinbaseCommerce\PaymentLink\`- **Commerce API docs:** [commerce.coinbase.com/docs/api](https://commerce.coinbase.com/docs/api/)
- **Payment Link API docs:** [docs.cdp.coinbase.com/commerce-onchain/docs/payment-links](https://docs.cdp.coinbase.com/commerce-onchain/docs/payment-links)
- [Migrate from Commerce Overview](https://docs.cdp.coinbase.com/coinbase-business/payment-link-apis/migrate/overview)
- [Coinbase Business API Key Authentication](https://docs.cdp.coinbase.com/coinbase-business/authentication-authorization/api-key-authentication)

- [API & Schema Mapping](https://docs.cdp.coinbase.com/coinbase-business/payment-link-apis/migrate/api-schema-mapping)

All errors that occur during any interaction with either API will be raised as exceptions:

ErrorStatus CodeAPIException\*InvalidRequestException400ParamRequiredException400ValidationException400AuthenticationException401ResourceNotFoundException404RateLimitExceededException429InternalServerException500ServiceUnavailableException503Installation
------------

[](#installation)

Install with `composer`:

```
composer require detain/coinbase-commerce
```

This will also install `firebase/php-jwt` (required for the Payment Link API).

Usage
-----

[](#usage)

---

Commerce API (Legacy)
---------------------

[](#commerce-api-legacy)

To start using the Commerce API, register an account on [Coinbase Commerce](https://commerce.coinbase.com/signup). You will find your `API_KEY` from User Settings.

Initialize a `Client` for interacting with the API:

```
use CoinbaseCommerce\ApiClient;

//Make sure you don't store your API Key in your source code!
$apiClientObj = ApiClient::init();
$apiClientObj->setTimeout(3);
```

### Disable SSL Check

[](#disable-ssl-check)

```
$apiClientObj->verifySsl(false);
```

The API resource class provides the following static methods: `list, all, create, retrieve, updateById, deleteById`. Additionally, the API resource class also provides the following instance methods: `save, delete, insert, update`.

Each API method returns an `ApiResource` which represents the JSON response from the API. When the response data is parsed into objects, the appropriate `ApiResource` subclass will automatically be used.

### Warnings

[](#warnings)

It's prudent to be conscious of warnings. The library will log all warnings to a standard PSR-3 logger if one is configured.

```
use CoinbaseCommerce\ApiClient;

//Make sure you don't store your API Key in your source code!
$apiClientObj = ApiClient::init();
$apiClientObj->setLogger($logger);
```

Checkouts

Webhooks
--------

[](#webhooks)

### Verify Signature header

[](#verify-signature-header)

```
use CoinbaseCommerce\Webhook;

try {
    Webhook::verifySignature($signature, $body, $sharedSecret);
    echo 'Successfully verified';
} catch (\Exception $exception) {
    echo $exception->getMessage();
    echo 'Failed';
}
```

---

Payment Link API (New)
----------------------

[](#payment-link-api-new)

The Payment Link API uses CDP (Coinbase Developer Platform) API keys with ES256 JWT authentication. It currently supports **USDC** payments only.

More examples can be found in [`examples/PaymentLink/`](examples/PaymentLink/).

### Authentication

[](#authentication)

You'll need a CDP API key from the [Coinbase Developer Platform](https://portal.cdp.coinbase.com/). This gives you a **key name** (used as the JWT `sub`/`kid`) and an **EC private key** (PEM format) for ES256 signing.

```
use CoinbaseCommerce\PaymentLink\PaymentLinkClient;
use CoinbaseCommerce\PaymentLink\PaymentLink;

// Initialize the client with your CDP credentials
$client = new PaymentLinkClient(
    getenv('COINBASE_CDP_KEY_NAME'),      // CDP API key ID
    getenv('COINBASE_CDP_PRIVATE_KEY')     // EC private key PEM
);

// Optional: configure timeout (default 10s)
$client = new PaymentLinkClient($keyName, $privateKey, [
    'timeout' => 15,
]);

// Set the client for the static PaymentLink facade
PaymentLink::setClient($client);
```

### Create a Payment Link

[](#create-a-payment-link)

```
$result = PaymentLink::create([
    'amount' => '100.00',
    'currency' => 'USDC',
    'description' => 'Payment for order #12345',
    'successRedirectUrl' => 'https://example.com/success',
    'failRedirectUrl' => 'https://example.com/failed',
    'metadata' => [
        'orderId' => '12345',
        'customerId' => 'cust_abc123',
    ],
]);

echo "Payment URL: {$result['url']}\n";
echo "Status: {$result['status']}\n"; // ACTIVE
```

### Get a Payment Link

[](#get-a-payment-link)

```
$link = PaymentLink::get($linkId);
echo "Status: {$link['status']}\n";
```

### List Payment Links

[](#list-payment-links)

```
$list = PaymentLink::list([
    'pageSize' => 10,
    'status' => 'ACTIVE',
]);

foreach ($list['paymentLinks'] as $link) {
    echo "{$link['id']}: {$link['status']}\n";
}
```

### Deactivate a Payment Link

[](#deactivate-a-payment-link)

```
$deactivated = PaymentLink::deactivate($linkId);
echo "Status: {$deactivated['status']}\n"; // DEACTIVATED
```

### Idempotency

[](#idempotency)

Pass an idempotency key to safely retry `create` requests:

```
$result = PaymentLink::create($params, 'unique-request-id-123');
```

### Payment Link Webhooks

[](#payment-link-webhooks)

The Payment Link API uses a different webhook signature format (`X-Hook0-Signature`) than the Commerce API. See [`examples/PaymentLink/WebhookExample.php`](examples/PaymentLink/WebhookExample.php) for a complete example.

```
use CoinbaseCommerce\PaymentLink\PaymentLinkWebhook;

$payload = file_get_contents('php://input');
$signatureHeader = $_SERVER['HTTP_X_HOOK0_SIGNATURE'] ?? '';

// Collect request headers (normalized to lowercase keys)
$headers = [];
foreach ($_SERVER as $key => $value) {
    if (strpos($key, 'HTTP_') === 0) {
        $headerName = strtolower(str_replace('_', '-', substr($key, 5)));
        $headers[$headerName] = $value;
    }
}
$headers['content-type'] = $_SERVER['CONTENT_TYPE'] ?? 'application/json';

try {
    // Verifies signature, checks replay protection (5 min default), then parses JSON
    $event = PaymentLinkWebhook::buildEvent($payload, $signatureHeader, $webhookSecret, $headers);

    switch ($event['eventType']) {
        case 'payment_link.payment.success':
            // Fulfill the order
            break;
        case 'payment_link.payment.failed':
            // Handle failure
            break;
        case 'payment_link.payment.expired':
            // Handle expiry
            break;
    }

    http_response_code(200);
} catch (\CoinbaseCommerce\Exceptions\SignatureVerificationException $e) {
    http_response_code(400);
}
```
