Hi everyone, We are trying to access Koha data using Koha API from a different system. We are using the Angular JS V2 library to access Koha API. While accessing the API, we encountered a CORS error stating "Access to XMLHttpRequest at " http://opac.tucl.edu.np:81/api" from origin "http://localhost:4200" has been blocked by CORS policy. The detail of the error is provided in the screenshot below. We have also tried to set the value for the AccessControlAllowOrigin system preference with the value "http://localhost:4200". As it didn't resolve the issue, we also set the preference value as an asterisk '*'. However, we still encountered the same error. [image: error_2022-08-06_17-38-43-985.jpg] If anyone had already resolved this kind of issue earlier, please share your experience. We would highly appreciate it. Thank you. -- Regards, Dibyendra Hyoju
