confirmation for ipncheck and curltest

i have followed all the steps for setting up the paypal side and zencart side. Now there is some confusion... it might be the 3 or 4 hours of sleep ive had trying to setup the check out hehe.

I read everywhere that you need cURL to use the express check out. I sent an email to my hosting company asking if they were running a curl proxy server. They replied they do not run proxy servers but would be willing to install an SSL certificate for me.

Here is what i would like to know. I have downloaded the ipncheck and curltest and i believe they are coming back ok. But i am not sure if i have to edit the ipncheck.php or curltest.php to reflect my servers. I realize this may be simple but my head hurts from the lack of sleep heh.

As far as i can tell both test are good. if thats the case does the latest php come with cURL built in i have 5.2.5. Do i need to setup a SSL certificate to setup the paypal expess check out? Is it recommended? why?

(fyi i tried to test the checkout on my store but when it came to log into paypal it detected i was trying to log into the seller account and not the buyer, even they were the same account).

SSL Not required to use PPE or IPN, You might obtain one for the purpose of showing your customers that you are secure and protect their privacy when logging in etc.

Curl is not a default inclusion be can be compiled into the PHP by your host.

Check in admin > tools > server/Version info > look for curl

You can not purchase with the same account as you are purchasing from...

wow, thanks for replying so quickly cobra, i can sleep sound after checking into what you commented on. I've come to the conclusion of a couple of things.

1. I'm extremely happy with deciding to use zen-cart. I love the customization, the modules and most importantly the support from the community. I've had all my questions answered so quickly im speechless.

2. the person that answered my email from my hosting company has no idea what i was talking about. (To be fair i really didnt either when i sent it orginally lol).

3. Pretty sure i wasnt gonna be able to buy something using the seller's account. A least i know for the future.
