picking jwt token from cookie not the request - java

I am storing JWT token in the ResponseCookie with the sign in request but all other requests are authenticated without passing the Bearer token as it is getting picked up from the ResponseCookie and I dont think this is a usual flow of authentication.
I think all other requests should use the bearer token not the token from cookie storing the token

Action on endpoint /logout for JWT with refresh tokens

I used access token (JWT - expire after 10 minutes) and refresh token (expire after 24 hours) to authorization service running in a few cleints (mobile / web.. ).
I want to implement /logout endpoint and pass refresh token as query/path variable to delete refresh token from db and the same way disable possibility to create new access tokens only from one client.
Is good way?
How should works endpoint /logout.?
Second way is delete all refresh token by user-id (from access token) but then we loss access from every clients (web / mobile..) and it is bad use case.
Thank you for all the advice.
You can implement a standards compliant token revocation endpoint to revoke the refresh token and/or access token as specified in RFC 7009 OAuth2 .0 Token Revocation

How to generate JWT Token using Facebook credentials in Spring boot

I have one requirement that have to develop Spring boot Rest API for login using Facebook credentials and have to generate JWT token for this credentials and validate every request.
Thanks.
When the user logs in using facebook credentials, the user will be authenticated by the facebook and will issue the token that can be used for authorisation. My point is that once you authenticate the user on facebook, you get the credential. Instead of wrapping it into the JWT, store it somewhere with id and wrap that ID in the JWT. On each request, you will receive the JWT token and while authorising, you can get id from the JWT and get it from the persistence or store and authorise the user.
Let say you have the facebook tokens after login, then you have to store it somewhere using some id
String fbTokenId = storeFBToken(fbToken);. Using this token you can generate JWT token like:
Algorithm algorithm = Algorithm.HMAC256(key);
String token = JWT.create().withIssuer(author)
.withClaim("fbTokenId", fbTokenId)
.withSubject("user")
.sign(algorithm);
When you authorise the request, you will have the JWT token. Now you have to get verify the token and read the fbTokenId to verify it:
Algorithm algorithm = Algorithm.HMAC256(key);
JWTVerifier verifier = JWT.require(algorithm).withIssuer(author)
.build();
DecodedJWT jwt = verifier.verify(token);
String fbTokenId = jwt.getClaim("fbTokenId").as(String.class);
String fbToken = getFBTokenFromStore(fbTokenId);
Before you jump into this, make sure you understand stateless authentication and authorisation concepts especially with tokens.

How to send back a JWT token with HttpURLConnection in java?

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.
Common are:
HTTP request headers (problem for XHR requests)
query parameters (bad idea because of caching/logging)
form fields (not universally useable)
URL segment (bad idea because of caching/logging)
certain cookies with the token as value (transparent) or
authentication header (typical)
The Authentication headers as defined in HTTP RFCs are typically be used with the Basic or 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);
for this.

JWT correct behaviour with invalid credentials

I would like to ask how to behave correctly when server receives user credentials which are not valid (username or password does not fit).
Should server send back an empty jwt token and set HttpStatus for 401
or is there any other preferable way?

paypal access token not returning

I trying to send a payment with my test application. Im using the paypal java sdk package.
Im not receiving my access token. Im receiving only the bearer token,
Bearer WesirDWp61YcTr8N8XWZHnPk7tCch.ZgcMvLfyp-FRA : appId :
APP-80W284485P519543T
Thus when I try to send a payment Im getting and 401 authorization error because of no access token. The first time I sent the request it returned the access token but every subsequent attempt brings this error:
Java exception "com.paypal.core.rest.PayPalRESTException: Error code : 401
with response : Server returned HTTP resp" when calling method "create" with
signature "(Ljava.lang.String;)Lcom.paypal.api.payments.Payment;" in class
"com.paypal.api.payments.Payment".
I do not understand what is happening here . Am I completely missing the boat here?
Thank You for any response.
Hit this URL with POST Request on Postman.
POST https://api.sandbox.paypal.com/v1/oauth2/token
On Authorization choose basic auth and enter the username as a clientID and password as a ClientSecret.
In Header set Content-Type: application/x-www-form-urlencoded
In Body seelect x-www-form-urlencoded and write grant_type: client_credentials
after that send request you will get the access_token
The bearer token is the access token, more specifically it is the type of access token returned. As per the REST API Reference (which is what the java sdk calls), the call to the oauth end point returns:
{
"scope": "https://api.paypal.com/v1/payments/.* https://api.paypal.com/v1/vault/credit-card https://api.paypal.com/v1/vault/credit-card/.*",
"access_token": "EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG",
"token_type": "Bearer",
"app_id": "APP-6XR95014SS315863X",
"expires_in": 28800
}
The SDK combines the two fields and returns them as the "Bearer token".
This bearer token is all you need to access the REST APIs (with some restrictions based on the permissions/scopes requested and how the bearer token was requested, however that is dependent on creation call). Pass the bearer token in the authorization header:
"Authorization: Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG"
