Considering a custom Payment Method class extending \Magento\Payment\Model\Method\AbstractMethod: Would somebody kindly explain what do the methods below do?

initialize($paymentAction, $stateObject)
validate()

order(\Magento\Payment\Model\InfoInterface $payment, $amount)
authorize(\Magento\Payment\Model\InfoInterface $payment, $amount)

capture(\Magento\Payment\Model\InfoInterface $payment, $amount)
refund(\Magento\Payment\Model\InfoInterface $payment, $amount)
cancel(\Magento\Payment\Model\InfoInterface $payment)
void(\Magento\Payment\Model\InfoInterface $payment)

Thanks!

  1. initialize: Instantiate state and set it to state object. Method that will be executed instead of authorize or capture if flag isInitializeNeeded set to true.

  2. validate: Validate payment method information that means validate payment method is allowed for billing country or not.

  3. order: Check order availability.
  4. authorize: Payment process authorize only. After authorize, you need to capture amount manually.
  5. capture: Capture payment amount. When this method called, system automatically capture amount.
  6. refund: Refund specified amount for payment.
  7. cancel: Cancel payment.
  8. void: void specified amount for payment. Some payment method don't allow refund within 24hrs. So in that case you need to call void for refund that amount.

[Update]

Where actually during checkout process does authorize and capture is being called?

Solution:

Open Magento/Sales/Model/Order/Payment.php Check following method.

  1. place
  2. processAction
  • Thanks for your answer. Just 2 questions: 1) What does 'void specified amount' mean? 2) Where does 'capture' actually being called? – Pro-Magento Jan 27 '17 at 14:09

  • 'void specified amount' mean -> you can specified how much you need to void. – Sohel Rana Jan 27 '17 at 14:15
  • Where actually during checkout process does authorize and capture is being called? For my module only validate is called! – Pro-Magento Jan 27 '17 at 14:21

It's as deprecated approach to extend \Magento\Payment\Model\Method\AbstractMethod, instead, you should use Magento payment gateway.

You can find the step-by-step guide how to implement payment method on Magento 2 dev docs based on Magento payment gateway.

Also, Magento has sale(authorize & capture) payment action - it's similar to authorize, but allows process the capturing action for an authorized transaction. This post describes how to implement sale payment action - https://community.magento.com/t5/Magento-DevBlog/The-Magento-Sale-Payment-Operation/ba-p/67251.

  • Thank you for the answer. I'll take a look into it. I've up-voted your answer. – Pro-Magento Jan 27 '17 at 14:51
