Provides a simple API to access payment gateways and process payments as a module hook.

Completed payments are stored in the database.

Two gateways are currently supported: PayPal and Moneybookers.

Payment forms can be created easily, for example:

function example_paypal_form($form_state, $product_id) {

  $vars = array(
    'module' => 'example',
    'type' => 'example type',
    'custom' => $product_id,
    'item_name' => 'Example payment',
    'no_shipping' => TRUE,
    'no_note' => TRUE,
    'return' => url('', array('absolute' => TRUE)),
    'amount' => 100,
  $form = simple_payments_paypal_payment_form($vars);

  $form['button'] = array(
    '#type' => 'button',
    '#value' => t('Pay with PayPal'),

  return $form;

$output = drupal_get_form('example_paypal_form', $product_id);

Completed payments can be processed with hook_simple_payment_process($payment) .

The API is documented in more detail in the source code in Doxygen format.

A couple of PayPal payment verification functions were derived from Simple Paypal framework.

If you need something more elaborate (like a cart!), use Commerce.
