Hi @Chathura Karunarathna,

Looks like you are trying to access API Doc of an environment hosted in ifs.cloud domain from your local computer and getting a 403: Unauthorized error. You can directly access API Doc only in CORS(Cross-Origin Resource Sharing) enabled environments according to following documentation.

https://docs.ifs.com/techdocs/foundation1/045_administration_aurena/240_integration/010_api_doc/default.htm

This is usually a configuration set in server side that clients decide to enforce or not. All modern browsers enforce this but tools like Postman do not. So you can see whether you get the same error with Postman. You may get a 401: Unauthorized error though, in which case you may have to provide authorization details.

Hope this helps!
