Sending JWT token in the headers with Postman - express

Question

I'm testing an implementation of JWT Token based security based off the following article. I have successfully received a token from the test server. I can't figure out how to have the Chrome POSTMAN REST Client program send the token in the header.
My questions are as follows:
1) Am I using the right header name and/or POSTMAN interface?
2) Do I need to base 64 encode the token? I thought I could just send the token back.

Answer 1

For the request Header name just use Authorization.
Place Bearer before the Token. I just tried it out and it works for me.
Authorization: Bearer TOKEN_STRING
Each part of the JWT is a base64url encoded value.

Answer 2

Here is an image if it helps :)
Update:
The postman team added "Bearer token" to the "authorization tab":

I am adding to this question a little interesting tip that may help you guys testing JWT Apis.
Its is very simple actually.
When you log in, in your Api (login endpoint), you will immediately receive your token, and as #mick-cullen said you will have to use the JWT on your header as:
Authorization: Bearer TOKEN_STRING
Now if you like to automate or just make your life easier, your tests you can save the token as a global that you can call on all other endpoints as:
Authorization: Bearer {{jwt_token}}
On Postman:
Then make a Global variable in postman as jwt_token = TOKEN_STRING.
On your login endpoint:
To make it useful, add on the beginning of the Tests Tab add:
var data = JSON.parse(responseBody);
postman.clearGlobalVariable("jwt_token");
postman.setGlobalVariable("jwt_token", data.jwt_token);
I am guessing that your api is returning the token as a json on the response as:
{"jwt_token":"TOKEN_STRING"}, there may be some sort of variation.
On the first line you add the response to the data varibale.
Clean your Global
And assign the value.
So now you have your token on the global variable, what makes easy to use Authorization: Bearer {{jwt_token}} on all your endpoints.
Hope this tip helps.

Here is how to set token this automatically
On your login/auth request
Then for authenticated page

Answer 5

I had the same issue in Flask and after trying the first 2 solutions which are the same (Authorization: Bearer <token>), and getting this:
{
"description": "Unsupported authorization type",
"error": "Invalid JWT header",
"status_code": 401
}
I managed to finally solve it by using:
Authorization: jwt <token>
Thought it might save some time to people who encounter the same thing.

Answer 6

If you wish to use postman the right way is to use the headers as such
key: Authorization
value: jwt {token}
as simple as that.

Answer 7

Open postman.
go to "header" field.
there one can see "key value" blanks.
in key type "Authorization".
in value type "Bearer(space)your_access_token_value".
Done!

Answer 8

For people who are using wordpress plugin Advanced Access Manager to open up the JWT Authentication.
The Header field should put Authentication instead of Authorization
AAM mentioned it inside their documentation,
Note! AAM does not use standard Authorization header as it is skipped
by most Apache servers. ...
Hope it helps someone! Thanks for other answers helped me alot too!!

Answer 9

Everything else ie. Params, Authorization, Body, Pre-request Script, Tests is empty, just open the Headers tab and add as shown in image. Its the same for GET request as well.

Answer 10

I did as how moplin mentioned .But in my case service send the JWT in response headers ,as a value under the key "Authorization".
Authorization →Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJpbWFsIiwiZXhwIjoxNDk4OTIwOTEyfQ.dYEbf4x5TGr_kTtwywKPI2S-xYhsp5RIIBdOa_wl9soqaFkUUKfy73kaMAv_c-6cxTAqBwtskOfr-Gm3QI0gpQ
What I did was ,make a Global variable in postman as
key->jwt
value->blahblah
in login request->Tests Tab, add
postman.clearGlobalVariable("jwt");
postman.setGlobalVariable("jwt", postman.getResponseHeader("Authorization"));
in other requests select the Headers tab and give
key->Authorization
value->{{jwt}}

Answer 11

Somehow postman didn't work for me.
I had to use a chrome extension called RESTED which did work.

Answer 12

In Postman latest version(7++) may be there is no Bearer field in Authorization
So go to Header tab
select key as Authorization and in value write JWT

Answer 13

x-access-token on headers works for me.
key: x-access-token
value: token
