I’m having problems to find the latest API version of PayPal. The current version

  • 0

I’m having problems to find the latest API version of PayPal. The current version that I found is 51.0, but it’s not the latest version.

I need to add items to the payment summary, and the version has to be >= 53.0.

Where do I find the latest PHP API examples? (NVP)

    You can refer here for PayPal API Reference, scroll a little lower to see your NVP reference.

    As I undestood you are trying to customize the Express Checkout, refer here for PayPal Express Checkout Integration Guide (PDF).

    While technical documentation page here.

    As I browse on those, it appears it is updated sometime in April 2012.

    Just use the current PayPal API version. Current version is 89.0. This seems to be tricky but finding the API version of PayPal is by viewing the source code of the PayPal web page. You’ll see a snip in the header like this:

    <!--
        Script info: script: webscr, cmd: _home, template: xpt/Marketing_CommandDriven/homepage/MainHome, date: May 9, 2012 08:36:29 PDT; country: US, language: en_US, xslt server: 
        web version: 89.0-2920756 branch: UPR_890_int
        content version: -
        pexml version: 89.0-2896586
        page XSL: Marketing_CommandDriven/default/en_US/homepage/MainHome.xsl
       hostname : HuqmOnXTzOtlL7CprWmgAQwFlQK1lZ0z6u5fc-r5fMk
         rlogid : HuqmOnXTzOtlL7CprWmgAYVSw2GbAGynG1%2bkpma0nBQchRCqNea%2ffA%3d%3d_1374663724c
-->

    web version: 89.0-2920756 states the API version. Seems not reliable right? I just follow this thread month ago when I did some project requiring PayPal. But hey, it’s working.
