GET Method with JSON body and Bearer Authorization with RestTemplate

I know.... this is not the best practice, but i've been asked for this:

I'm trying to get an endpoint that receives a json body with 3 parameters (int, int, int) and has a Bearer Authentication.

Headers

header.setContentType(MediaType.APPLICATION_JSON);
header.set("authorization", bearerToken);

Entity

HttpEntity<String> entity = new HttpEntity<>(requestjson.toString(), header);

RestTemplate

ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.GET, entity, String.class);

System.out.print(entity):

<{"1stParam":1,"2ndParam":4881,"3rdParam":0},{Content-Type=[application/json], authorization=[Bearer bearerToken]}>

besides security and all that kind of problems, the request shows a 400 HTTP response via RestTemplate, Postman works fine.

I also tried HttpURLConnection but had same problem.

Thank you for your help :)

I just coded a similar solution, so I'm pretty sure I know what this is. You have to include Bearer in the Authorization header. I think this code change will fix your problem:

header.set("Authorization", "Bearer " + bearerToken);

I capitalized the header key. I don't think this matters, but I know that the capitalized version just worked for me. My code looks just like this, and it works.

The basic idea here is that an Authorization header has to always start with the kind of authorization being performed, so that the server can know kind you want to use. It makes sense that this is a 400 error and not a 404, because the header is technically malformed.
