Simplepay server-to-server payment API note:

NOTE: You should be fully PCI compliant if you wish to perform an initial payment request server-to-server (as it requires that you collect the card data). If you are not fully PCI compliant, you can use Simplepay.js to collect the payment data securely.

Path to Config file:

	/src/Config/simplepay.php

Environment variables used:

	SIMPLEPAY_TEST_ENDPOINT=https://test.oppwa.com/
	SIMPLEPAY_LIVE_ENDPOINT=https://oppwa.com/
	SIMPLEPAY_VERSION=v1
	SIMPLEPAY_API_ENVIRONMENT=test
	SIMPLEPAY_USER_ID = replace with your userId
	SIMPLEPAY_ENTITY_ID = replace with your entityid
	SIMPLEPAY_PASSWORD = replace with your password

Synchronous workflow

Each paymentBrand follows one of two workflows: asynchronous or synchronous. In a synchronous workflow the payment data is sent directly in the server-to-server initial payment request and the payment is processed straight away.

1. Send an Initial Payment

Asynchronous workflow

In an asynchronous workflow a redirection takes place to allow the account holder to complete/verify the payment. After this the account holder is redirected back to the shopperResultUrl and the status of the payment can be queried.

1. Send an Initial Payment
2. Redirect the shopper
3. Get the payment status

Send an Initial Payment: use method [requestAsyncPayment] for making initial payment

Redirect the Shopper:

The next step is to redirect the account holder. To do this you must parse the redirect_url from the Initial Payment response along with any parameters. If parameters are present they should be POST in the redirect, otherwise a straight forward redirect to the redirect_url is sufficient.

Get the payment status: use method [requestPaymentStatus] for checking the payment status

#Tokenization & Registration: Simplepay note: NOTE: You should be fully PCI compliant if you wish to perform tokenization requests server-to-server (as it requires that you collect the card data). If you are not fully PCI compliant, you can use the Simplepay.js tokenization tutorial to collect the payment data securely.

One-Click payment : This method reqires 3 steps: 1. Authenticate user 2. Show Checkout 3. Send Payment

Step 1: Authenticate user
You will need a method to authenticate the customer against your records in order to obtain their respective registration.id (token) associated with their account.

    registrationId (token): You can use 'createTokenWithOutPayment' method to store customer's card details (without making paymnet) or use 'makeSyncPayments' method, and set createRegistration to true, to get the registrationId for user's card.
    account brand: brand of customer's card 
    last four digits of account number
    expiry date (if applicable)

Step 2: Show Checkout Form:
Create a form, to show user's all stored cards (You need to create form similar to this  https://docs.simplepays.com/sites/default/files/one-click-checkout.png) and show the list of all the cards you have stored. You can take example of html from page "https://docs.simplepays.com/tutorials/server-to-server/one-click-payment-guide".
