I am using an API to get some information. At the beginning of each session you need to get a JWT token to be able to send requests to the API. After I've got the token and I try to send a request, I get an error saying I'm unauthorized, which is fair since I did not attach the token in my request. The problem is that the documentation for the API does not explain how to do this, and I haven't been able to find it anywhere else either. How do I do this? I am doing this is Java and is using their own HttpURLConnection. Hopefully you understand what I mean.
Thank you in advanced!
It depends on how the web-service (API) wants to have the token represented.
The Authentication headers as defined in HTTP RFCs are typically be used with the
Digest authorization scheme. In case a string (token) authenticates the bearer of that token, the "Bearer" scheme is used (for example defined for OAuth2 in RFC6750).
You would use
uc.setRequestProperty("Authorization","Bearer " + jwt);
