CORS policy

Hello,

When I am trying to fetch the api request, in certain condition, I get this error:

"Access to fetch at 'https://api.poap.tech/...' from origin 'https://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled."

Is there a way to deactivate the No 'Access-Control-Allow-Origin' header on the Server Side?
