Paypal支付集成选择

Question

i have to integrate paypal payment gateway in php and iam in a state of confusion of selecting which method i have to choose.

I have gone through paypal developers documentation and found two methods.

1) REST API 2) Classic API

In classic apis there are still lot other options.

I have to build a website with payment feature for a client in US and no other country will be using this website.

So which option will be best suitable and on what scenario i have to select REST API and Classic API.

Answer 1

PayPal Classic and REST API

Classic API

• Request and response payloads are formatted as NVP and SOAP.

• Official PayPal SDK support for Express Checkout available with the PayPal Merchant SDK for .NET (GitHub | NuGet)

REST API

• Request and response payloads are formatted as JSON

• Official PayPal SDK support available with the PayPal .NET SDK (GitHub | NuGet)

The PayPal Name-Value Pair API (NVP API) enables you to leverage the functionality of the PayPal API by simply sending an HTTP request to PayPal and specifying request parameters using name-value pairs. The NVP API is a lightweight alternative to the PayPal SOAP API and provides access to the same set of functionality as the SOAP API.

A few points to consider with respect to Classic API vs. REST API :

• Classic API is not going to be deprecated any time soon. You can use Classic API.

• Moreover REST API does not support many variables/parameters that work in Classic API.

• REST API can be used for both credit card and PayPal payments (express checkout architecture).

Note: The REST Apis, they support both direct credit card and express checkout depending on which funding instrument (CC vs PayPal) you pass in the pay request.
