Usage

Below are a few common examples on how to use the Mollie PHP API client. For advanced usage please see the documentation.

Initializing the Mollie API client class

<?php

  // Import the namespace
  use Mollie\API\Mollie;

  // Create an API client instance
  $mollie = new Mollie('test_yourapikeyhere');

  // Alternatively..
  $mollie = new Mollie();
  $mollie->setApiKey('test_yourapikeyhere');

  // Now you're ready to use the Mollie API, please read on for more examples.

Creating a new customer

<?php
  use Mollie\API\Mollie;

  // Initialize API client
  $mollie = new Mollie('test_yourapikeyhere');

  // Create customer
  $customer = $mollie->customer()->create('John Doe', 'john.doe@example.org');

  // Alternatively you can also specify a locale and/or metadata.
  // In the following example we'll create the same customer with some metadata
  $customer = $mollie->customer()->create(
    'John Doe',
    'john.doe@example.org',
    array(
      'user_id' => 11,
      'group' => 'regular_customers'
    )
  );

  // Now save the customer ID to your database for future reference. Pseudo code:
  $db->save($customer->id);

Payments

Regular payment

<?php
  use Mollie\API\Mollie;

  // Initialize API client
  $mollie = new Mollie('test_yourapikeyhere');

  // Create new payment
  $payment = $mollie->payment()->create(
    10.00,
    'Expensive cup of coffee',
    'https://example.org/order/101'
  );

  // Redirect user to payment page
  $payment->gotoPaymentPage();

  $mollie = new Mollie('test_yourapikeyhere');

  // Create new payment
  $payment = $mollie->customer('cst_test')->payment()->create(
    10.00,
    'Expensive cup of coffee',
    'https://example.org/order/101'
  );

  exit; // Do redirect immediately

Recurring payments

Getting a recurring payment mandate

<?php
  use Mollie\API\Mollie;

  // Initialize API client
  $mollie = new Mollie('test_yourapikeyhere');

  // Get customer
  $customer = $mollie->customer('cst_test')->get();

  // Make sure the customer has no valid mandates
  if(!$customer->mandate()->hasValid()) {
    // Create mandate by issueing the first recurring payment.
    // This is usually a small amount like a few cents as it's only used to confirm
    // the payment details.
    $customer->mandate()->createFirstRecurring(
      0.01,
      'Recurring payment mandate confirmation',
      'https://example.org/account'
    );
  }

Create a recurring payment

<?php
  use Mollie\API\Mollie;

  // Initialize API client
  $mollie = new Mollie('test_yourapikeyhere');

  // Get customer
  $customer = $mollie->customer('cst_test')->get();

  // Check if customer has a valid mandate for recurring payments
  if($customer->mandate()->hasValid()) {
    $customer->payment()->createRecurring(10.00, 'Expensive cup of coffee');
  }
  else {
    // Customer has no valid mandates, you should get one first.
  }
