Getting Started with Paypal Server SDK

Introduction

An order represents a payment between two or more parties. Use the Orders API to create, update, retrieve, authorize, and capture orders., Call the Payments API to authorize payments, capture authorized payments, refund payments that have already been captured, and show payment information. Use the Payments API in conjunction with the Orders API. For more information, see the PayPal Checkout Overview., The Payment Method Tokens API saves payment methods so payers don't have to enter details for future transactions. Payers can check out faster or pay without being present after they agree to save a payment method.

The API associates a payment method with a temporary setup token. Pass the setup token to the API to exchange the setup token for a permanent token.

The permanent token represents a payment method that's saved to the vault. This token can be used repeatedly for checkout or recurring transactions such as subscriptions.

The Payment Method Tokens API is available in the US only.

enableRetries	bool	Whether to enable retries and backoff feature. Default: false
numberOfRetries	int	The number of retries to make. Default: 0
retryInterval	float	The retry time interval between the endpoint calls. Default: 1
backOffFactor	float	Exponential backoff factor to increase interval between retries. Default: 2
maximumRetryWaitTime	int	The maximum wait time in seconds for overall retrying requests. Default: 0
retryOnTimeout	bool	Whether to retry on request timeout. Default: true
httpStatusCodesToRetry	array	Http status codes to retry against. Default: 408, 413, 429, 500, 502, 503, 504, 521, 522, 524

    ->clientCredentialsAuthCredentials(
        ClientCredentialsAuthCredentialsBuilder::init(
            'OAuthClientId',
            'OAuthClientSecret'
        )
    )
    ->environment(Environment::SANDBOX)
    ->loggingConfiguration(
        LoggingConfigurationBuilder::init()
            ->level(LogLevel::INFO)
            ->requestConfiguration(RequestLoggingConfigurationBuilder::init()->body(true))
            ->responseConfiguration(ResponseLoggingConfigurationBuilder::init()->headers(true))
    )
    ->build();

API calls return an ApiResponse object that includes the following fields:
