Pay API Operation

Pay Examples Using NVP and CURL

These examples all use NVP for the data binding and CURL to deliver the HTTP request to

the PayPal sandbox endpoint. Line breaks are provided for ease of reading; each CURL

command is a single line and each request and response is a string without line breaks or extra

whitespace.

Simple payment example

In this example, the sender makes a payment of $100 to a PayPal-registered receiver. If you

are the sender and the caller, the approval is implicit; otherwise, the sender must explicitly

approve the payment.

The status of the request, which is identified in the paymentExecStatus field of the

response, differs due to the kind of approval required. Implicit approval allows the request to

be completed immediately. Explicit approval allows the request to be created; however, it is

completed until the payment is approved.

NOTE: The sample code below uses the insecure setting to work around the certificate for

testing in a sandbox environment. For actual implementations, you must specify the

location of the certificate.

Request:

correlationId xs:string

Correlation identifier. It is a 13-character, alphanumeric string (for example,

db87c705a910e) that is used only by PayPal Merchant Technical Support.

NOTE: You must log and store this data for every response you receive.

PayPal Technical Support uses the information to assist with reported

issues.

timestamp xs:datetime

Date on which the response was sent, for example:

2012-04-02T22:33:35.774-07:00

NOTE: You must log and store this data for every response you receive.

PayPal Technical Support uses the information to assist with reported

issues.
