Problem using Envato API to verify purchase

Hey guys,

I try to verify purchase with the new envato API and found the helper PHP class by dtbaker:
https://dtbaker.net/envato/envato-api-php-code-samples/

I also created a token (no oAuth) and test the API with Postman, e.g.:
https://api.envato.com/v1/market/private/user/verify-purchase:purchase_code_here.json

Then I tried the PHP class from dtbaker on my server and there I get an Access Denied:

Access Denied
You don’t have permission to access "http://api.envato.com/v1/market/private/user/verify-purchase:

So for some reason I am not able to access the API from my server. Does anybody have an hint for that?

Thank you

Hi. I have exactly the same problem. I am getting 403 error:

You don't have permission to access "http://api.envato.com/v3/market/author/sale?" on this server.

It works in Postman, but it does not work on my server. I’ve contacted Envato support.
