# Manage Customers

How to create, update, and delete customers using the Mollie API.

## Create a Customer

```php
use Mollie\Api\Http\Requests\CreateCustomerRequest;

try {
    // Create a new customer
    $customer = $mollie->send(
        new CreateCustomerRequest(
            name: 'Luke Skywalker',
            email: 'luke@example.com',
            locale: 'en_US',
            metadata: [
                'isJedi' => true
            ]
        )
    );

    echo "New customer created: {$customer->id}\n";
} catch (\Mollie\Api\Exceptions\ApiException $e) {
    echo "API call failed: " . htmlspecialchars($e->getMessage());
}
```

## Update a Customer

```php
use Mollie\Api\Http\Requests\GetCustomerRequest;
use Mollie\Api\Http\Requests\UpdateCustomerRequest;

try {
    // First retrieve the customer you want to update
    $customer = $mollie->send(
        new GetCustomerRequest(
            id: 'cst_8wmqcHMN4U'
        )
    );

    // Update specific customer fields
    $customer = $mollie->send(
        new UpdateCustomerRequest(
            id: $customer->id,
            name: 'Luke Sky',
            email: 'luke@example.com',
            locale: 'en_US',
            metadata: [
                'isJedi' => true
            ]
            // Fields we don't specify will keep their current values
        )
    );

    echo "Customer updated: {$customer->name}\n";
} catch (\Mollie\Api\Exceptions\ApiException $e) {
    echo "API call failed: " . htmlspecialchars($e->getMessage());
}
```

## Delete a Customer

```php
use Mollie\Api\Http\Requests\DeleteCustomerRequest;

try {
    // Delete a customer
    $mollie->send(
        new DeleteCustomerRequest(
            id: 'cst_8wmqcHMN4U'
        )
    );

    echo "Customer deleted\n";
} catch (\Mollie\Api\Exceptions\ApiException $e) {
    echo "API call failed: " . htmlspecialchars($e->getMessage());
}
```
