CORS error to external API call

Hi there,

Hope you are doing well.
We are making call to external API using BS player but it is giving us COS error:

http://localhost:8081/sd/applet/da3bdfc3004c90eedb125ff6c2ed3d2ebcc92679a61c67f93b/1.2.3/1576691021217/index.html:0]: Failed to load http://dlm.datacall.tech/p/cr/?FeedType=ccef&DataType=JSON&LocationType=zip&Location=undefined: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8081' is therefore not allowed access.

We found below ticket but not solution mentioned there.

Any help would be appreciated.
Thanks
