How to set up PayPal to use the eBay Payment Gateway and eBay Ecommerce Payments API?
We can do it all using a simple PHP script.
The PayPal Developer Guide has all the details.
We’ve taken the lead from a similar project, and we’re using it to create an ecommerce payments gateway.
This article is based on a previous tutorial, and covers the steps to setup a PayPal payment gateway in PHP.
The tutorial was originally published in May 2018, but the most recent version of the guide can be found here.
The PayPal API can be used to integrate with many of the popular payment services, including Amazon, eBay, PayPal, Stripe, and others.
But the API itself is limited in functionality.
It doesn’t provide a payment gateway or payment processor.
PayPal is a payment processor and the API is not able to do payment processing for them.
PayPal’s API is available to third parties, but it’s not enabled by default for anyone.
We can easily get around this limitation by adding a PayPal Payments API to the PHP extension, called PayPalPaymentsAPI .
PayPalPaymentAPI is available in the PHP Composer repository, but there are a few steps you need to take before you can use it.

In this tutorial, we’re going to set this up with the PayPal Payment Gateway API.
To use PayPal PayPPAcess API, we need to create a new PHP file called PayPal.php .
This file will be our base for all our PayPal functionality.
We’re going with a simple PayPalPaypipeline.php extension.
This extension creates a PHP class, which is a PHP object with a constructor that takes in a list of parameters and a method that will be called when a new transaction is added to the PayPal Payments database.
The constructor accepts the following arguments:The parameters in the constructor are the fields we’re setting up to populate the PayPal payments database.
Here we’ll use the default payment amount and the amount to which we’re paying.
The return value from the constructor is a new PayPalPayPaketimplePaymentType is a string representing the type of PayPalPayPayPayTransaction is a reference to a PayPalPayTransaction object.
The value returned by the constructor will be the PayPayTransaction instance.
The PayPayPayConnection object will contain a connection object to the database.
It will allow us to get and set data about the transaction, as well as handle other transaction related actions.
The following example will create a transaction that sends money to a customer and sends it to a third party.
The payment amount is set to $5.00, and the transaction ID is 123456.
The next two lines add a new class to the base class:Now that we have a PayPayPipeline extension, we can use the PayPal API to make PayPalPayProcessing calls.
To do so, we’ll create a constructor called PayPalPPActionProcessing that accepts two arguments, the first being the amount of money to be processed and the second being the type and amount of the transaction.
The constructor accepts parameters as shown in the following code example:The constructor is very simple, but lets us customize the payment processing code a little bit.
We’ll add a function that calls the PayPalpaymentPipelines method when the transaction is completed.
We add the following function:The following two lines modify the PayPal payment pipeline so that the PayPal processor receives the completed transaction, and then sends it back to the payment processor for payment.
The second line modifies the code to handle the other transaction that was added to our database:We can see that we’re creating a payment pipeline that will send a PayPalChargePipetimblePayment type to the third party, which will then use the thirdparty payment processor to process the transaction for us.
In order to do this, we’ve changed the payment pipeline logic to look like this:So, now that we’ve set up a payment processing pipeline for the third-party company, we have to add it to the PayPipeles pipeline.
The following two code snippets create a pipeline that sends the transaction to the eBay Payments API.
We create a PayPalPipelaProcessing class and a PayPalPerpipelaPipeling class to pass the transaction into the PayPalPerpetelesPipework class.
We use the following two functions in the PayPalPipePipline class to call the PayPalprocessor method.
The function we call is called by the PayPalProcessing object.
The function we pass to the code is called after we’ve created the PayPalpayPipenesPipeworks object.
When the transaction has been completed, the PayPal process will send the completed PayPalPayChargePipe to the ecommerce payment gateway, which then process the payment for us and return a
