It is easily one of the most recognisable payment brands on the web today. In this article we're going to look at a simple example that will use PayPal's SDK to take payments using PHP and MySQL.The process of taking a payment via PayPal's REST API can be broken down into the following steps:-In order to keep things simple for our example we're going to split the request and response into two separate files and load all our common functionality in via a bootstrap file:-Then all the front-end will be handled by some HTML files:-PayPal provides a really useful PHP SDK for working with the REST API. This is then added to a 'transaction' object along with a description of the transaction and an invoice number. For the payer part we need to set up the payment method to be 'paypal'.Next let's generate the transaction itself. The cancel URL is where the customer returns to our site if they decide to terminate the purchase.With the payer, transaction and redirect URLs set up we can now build our payment object.We're telling PayPal here our intention is to make a 'sale' by using setIntent(). If you're already using Composer in your project you'll hopefully already be doing this somewhere. A request is issued from your server to PayPal for a payment to be made 3. This repository has been archived by the owner. You receive a notification from PayPal that a payment record has been initiated, the response is processed and we complete the payment 5. The cancel URL will be where customer's are sent if they decide to cancel the transaction and return to our site.In order to interact with PayPal's REST API we need to authenticate against it and create an API context object that we can use to get and make payments.For testing $enableSandbox is set to true in our example code.
Merchants who have not updated their PHP Checkout SDK to version 1.0.1 will not be able to deserialize responses using outdated SDK integrations.All PHP Checkout SDK integrations are expected to be updated by March 1, 2020. PayPal Developer Docs Checkout Add checkout buttons to your page and more; PayPal Commerce Platform Add an end-to-end payment solution; Subscriptions Add recurring billing as a payment option; Payouts Send money to many recipients at the same time; Invoicing Set up invoicing in your order management system; View All; APIs. The description can be anything you want and will show up in PayPal against the order details of the payment to help you understand what the payment was for.We now need to set the redirect URLs. Our getApiContext function looks like this:-In this function we toggle between the sandbox and live by setting the mode using setConfig(). In PayPal's live environment 'DEBUG' is not an option and will throw a warning.With PayPal's SDK we need to build up a payment object that we can then generate an approval link with; we then use this link to redirect the customer to the PayPal website. for a delayed shipment); 'order' is used when you don't have all items in stock and want to take part payment for items you do have now and complete payment later for the rest of the items as they become available. Use the PayPal REST SDKs to get started quickly with the PayPal REST APIs and complete common actions. You can continue to use it, but no new features or support requests will be accepted. If you want to take real payments this would want toggling to false.

GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. We can also enable logging here which can be useful if you're trying to debug things.Logging is most verbose in the 'DEBUG' level. These will determine where PayPal sends the customer back to after they have confirmed the payment on PayPal's website. You can read about the differences between Finally we want to redirect the customer to PayPal.Once the customer clicks 'Continue' on the PayPal website to proceed with the transaction they will be redirected to the return URL we defined in our request action.Firstly we check that the query string contains the parameters we expect to be returned by PayPal in order to complete the transaction.If the query string looks good we proceed to complete the transaction (so far money hasn't changed hands).
PayPal provides a sandbox for doing this which allows us to create fake accounts for testing both the buyer and seller experiences.
We attempt to retrieve the payment from PayPal to check it went through okay and write it to our database.If the payment is successful it will have the state 'approved'. For a production site this should be switched to 'INFO' which logs less detail. Our extensive base of clients includes large UK and international organisations.
