Bearer Token Header with OKHttp



I am currently using retrofit within an android app, and okhttp client.

When signing my request headers with the auth token using the required format

"Bearer " I get an illegalargumentexception from okhttp.
Removing the space between “Bearer” and the “” resolves this issue, but now my requests into the api are failing with a 403 (UnAuthorized).

Has anyone faced this before ?


I never used retrofit, but the value of the Authorization header should be Bearer+[Token] where the + represents an white space. If you’re trying to set it to just Bearer+ then it does not seem correct.

In addition, if you haven’t done so already you should check:


Thanks for your reply. I am adding the white space as outlined in the docs.

The stackoverflow link is exactly what I am doing in my current code, but it made me realize i was setting the token as the key, and the key as the value.

Issue is now resolved.
