We have a REST API that is used by our Blazor spa application which exposes a feature to initiate an oAuth handshake against some line of business system for the purpose of obtaining an access token and ultimately accessing data. Some of these third party systems, can at times, have somewhat of a non-standard oAuth implementation and require additional headers or query parameters. As such the API builds the 302 response which we send back to the Blazor client. Forgive my ignore here as I am not a front-end developer but is it possible within Blazor to capture the 302 response and pop this open into a new browser tab? Upon searching for an answer it seems there’s a way to JS Interop to pop a tab and navigate to a URL but this isn’t what I want. I want the API to return a 302, with say 4 additional headers, and pass that response to the new browser tab?

If that isn’t possible should we pop a browser tab open first, then call the API and just have that new browser tab follow the 302?

Thanks!
