I am PHP developer, have a homepage where I want to integrate paypal express checkout. First I want to sell digital goods and later on also non digital goods like postcards etc.. I already have created the sandbox accounts and credentials. But I don't know the next step now.
I found following link:
http://paypal.github.io/#merchant
If I click on the PHP tab there is mentioned:
Without composer
curl https://raw.github.com/paypal/merchant-sdk-php/stable-php5.3/samples/install.php | php
Since I not use composer it seems to be the correct step for me, but what does this command do?
Do I need to download the SDK (provided in the Links section of the same page) first and the run this command?
I used this site to initiate with paypal http://www.phpkode.com/scripts/item/paypal-buy-now-and-ipn-classes/
Hope it helps
