Caller is not authorized to access this resource - AUTHORIZED_ERROR
We have created "NVP/Soap" Rest API credentials. We will need to implement Adaptive payment method in our web application. After getting response from your customer support they are saying youwill need to implement the PayPal Marketplace. We have tried to use that API but it's given a error like as "Caller is not authorized to access this resource - AUTHORIZED_ERROR" . Can you please enable the "Marketplace API" Access on sandbox so we will test and implement accordingly.
Your previous response just information to create shopping cart button and generate API key . We have already created it and test it with classic "Parallel Payment" but when we asking a Live "APP-ID" you have response that is not possible to give that because that process deprecated for new accounts.
Hence please provide us the "PayPal-Marketplace API " access in sandbox so we can check and implement it according our requirement.
