I have legacy WCF services.
The client application gets enhanced, so added an Web API layer for new functionality, having a facade layer to consumes the legacy WCF service.
In web api layer, token based authentication got implemented, want to make the legacy WCF call secured, understood it is complex to implement token authentication in WCF Service.
What are the option I have to authenticate the calls between the Web API and WCF Service.
I appreciate your valuable inputs.
