Verify purchase code in javascript

Hi.

In the javascript code I am using:

var url='http://marketplace.envato.com/api/edge/USERNAME/API-KEY/verify-purchase:550e8400-e29b-41d4-a716-446655440000.json';

$.getJSON(url, function(jd) {     
 var entire_purchase = jd["verify-purchase"];     
 var buyer_name = entire_purchase.buyer;         
 alert(buyer_name);
 });

I have the api key and username inserted but still can’t get it to work. So somewhere taht adding ?callback=? in the end of the url would help but it doesn’t.

Any idea what I am doing wrong? The code itself work ok if I have the json file localy for example, but need to read that one.

TNX!

Hi,

yes I am using the right username and api. If I open the js in a browser the json file is displayed ok. And if are put that content in a local file(was trying this on my localhost) it works ok. It seems that something is missing if using a JSON file from other server. Read something about that, but none solution worked. Any idea for the fix?

TNX!

I’m pretty sure you’ll get the info about a purchase only if you use the username and api of the item author.

Basically, only the author of the purchased item can verify a purchase.

This is what I get in the Console:

XMLHttpRequest cannot load http://marketplace.envato.com/api/edge/XXXXXXX/YYYYYYY/verify-purchase:550e8400-e29b-41d4-a716-446655440000.json. Request header field X-Requested-With is not allowed by Access-Control-Allow-Headers.

Any idea?

P.S. I am using the right username and api key, just didn’t insert it here on the forum.

You can’t do that. Read same origin policy – https://developer.mozilla.org/en-US/docs/JavaScript/Same_origin_policy_for_JavaScript

Print your json output on a local file, and fetch it via js from there

Hi again.

This is how it would look like:

tnx.

Here’s another read if what I posted earlier did not somewhat convince you – http://stackoverflow.com/questions/9327218/access-control-allow-origin-not-allowed-by

Bottom line is, you simply can’t.

Do it the smart way, use ajax + server side scripting to fetch the json output dynamically.

Hi,

if I use php to check the purchase code all goes ok. But I am testing this before submiting a form(bbpress: form.user-register)

<form … onsubmit=”return checkPurchaseCode()”.. >

So I have a js function called before submiting.

If I change action so some custom file (checkPurchase.php), I can(successful) check the purchase code there using php, but don’t know how to get back to submit the form (bbpress: form.user-register)

Any idea about this maybe?

I got it working via the Ajax call but since the server always returns a 403 when an invalid purchase code is supplied I tested it with the total users API request, it is going to be very similar for you.

Just an update, it doesn’t seem to be working with older browsers due to cross domain request restrictions. If this is a concern I would suggest using a php proxy method that sushipasta posted previously, you should also look into the following to get a better idea with how to work whit the API php side :-
