Question

I need paypal integration for paying order. What I already do is to integrate api http://ci-merchant.org/ . It works like it needs to.. go to paypal website, give me option to pay but after i press pay button it just relocate to my sucess definded page and offcourse doesnt make payment. Here is my php code for paypal:

$this->load->library('merchant');
        $this->merchant->load('paypal_express');
        $settings = $this->merchant->default_settings();

        $settings = array(
            'username' => '*',
            'password' => '*',
            'signature' => '*',
            'test_mode' => false,
            'solution_type' => array('type' => 'select', 'default' => 'Sole', 'options' => array(
            'Sole' => 'merchant_solution_type_sole',
            'Mark' => 'merchant_solution_type_mark')),
            'landing_page' => array('type' => 'select', 'default' => 'Billing', 'options' => array(
            'Billing'   => 'merchant_landing_page_billing',
            'Login'     => 'merchant_landing_page_login')));

        $this->merchant->initialize($settings);

        if(isset($_POST['pay'])){
            $params = array(
            'amount' => '0.20',
            'currency' => 'USD',
            'return_url' => 'pay/succesfull',
            'cancel_url' => 'pay/cancel');
            $response = $this->merchant->purchase($params);

            if ($response->success()){
                echo "paid sucesfuly";
            }
            else
            {
                $message = $response->message();
                echo('Error processing payment: ' . $message);
                exit;
            }

Here is print screen where should paying be completed, but after pressing Pay now it just goes to my sucessfull website.

Answer 1

It sounds like you're not completing the process. The entire flow of Express Checkout is...

1. Call SetExpress Checkout
2. Redirect user to PayPal with token
3. User reviews and clicks "Continue" or "Pay now" depending on integration method
4. User is sent back to the Return URL provided in SEC
5. Call GetExpressCheckoutDetails to obtain details about the buyer (this is actually optional based on integration method)
6. Call DoExpressCheckoutPayment to finalize the payment.

Sounds like you've got #1 - 4 taken care of, and maybe even #5, but you're missing #6. Until DECP is called, no transaction actually takes place. You must be missing that piece.
