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.

override_http_client_configuration	bool	The value which determines to override properties of the passed Http Client from the sdk user
http_call_back	HttpCallBack	The callback value that is invoked before and after an HTTP call is made to an endpoint
timeout	float	The value to use for connection timeout. Default: 60
max_retries	int	The number of times to retry an endpoint call if it fails. Default: 0
backoff_factor	float	A backoff factor to apply between attempts after the second try. Default: 2
retry_statuses	Array of int	The http statuses on which retry is to be done. Default: [408, 413, 429, 500, 502, 503, 504, 521, 522, 524]
retry_methods	Array of string	The http methods on which retry is to be done. Default: ['GET', 'PUT']

client_credentials_auth_credentials	ClientCredentialsAuthCredentials	The credential object for OAuth 2 Client Credentials Grant

The API client can be initialized as follows:

client = PaypalserversdkClient(
    client_credentials_auth_credentials=ClientCredentialsAuthCredentials(
        o_auth_client_id='OAuthClientId',
        o_auth_client_secret='OAuthClientSecret'
    ),
    environment=Environment.SANDBOX,
    logging_configuration=LoggingConfiguration(
        log_level=logging.INFO,
        request_logging_config=RequestLoggingConfiguration(
            log_body=True
        ),
        response_logging_config=ResponseLoggingConfiguration(
            log_headers=True
        )
    )
