I am creating a Magento oAuth 1.0 REST client and realized that every HTTP request was returning a Access Denied 403 error even with the correct oAuth 1.0 implementation. To solve this problem I had to follow these instructions in Magento core.
Why oAuth 1.0 default implementation return Access Denied?
Editing these two files in Magento core is a solution?
There is another fix for this problem like guest permissions or something like that?
