Integrating paypal standard payment to my web application. First time working on paypal integration. Created a sandbox account and created an app to generate client id and secret key. Used the same with integration (Using PHP Codeigniter). Everything worked fine with localhost (windows environment). Was able to do the test transactions. When i moved the same application to live domain ( hosted using Cpanel ), i am receiving the below error from paypal server Authentication failed due to invalid authentication credentials or a missing Authorization header Used the same sandbox credentials what i used in my localhost. But receiving the above error Any ideas on what the issue is?
