Getting session cookie from jira cloud /rest/auth/1/session does not work

I am trying to get a session cookie from:




I am pretty sure that the provided credentials are correct - I can login with them in the web interface. However the call made with Postman always returns:

{ "errorMessages": [ "Login failed" ], "errors": {}}

There is no response header that would give any more information why it fails.


What could be the reason? I was thinking that maybe it is catpcha, but I cannot check that, as I always get redirected to  when I try to access the Jira login page directly.

@M KCookie based authentication has been deprecated and removed for Jira cloud in favor of token based basic authentication.

You can learn more from this notification which is more then 6 months old -

Thank you for the information. I understand that token based authentication only applies to Jira cloud. Is there a way to implement authentication in javascript that would work for both Jira cloud and Jira server?

Cookie based authentication did work well for both server types.

@M KI made a small script in NodeJS for copying attachment from Server to Cloud (and vice versa), and I used BasicAuth for both. The only difference is in server/dc environment you have to use 'username' and 'password' combo whereas in cloud you have to use 'email' and 'api token' combo, when I made a UI for this, in form I mentioned this for users.

So I think BasicAuth is good enough for these kind of use cases.

Thank you. In the older server versions I am using a call to /session to get a session cookie. I guess I will have to change that to basic auth.

When calling jira server with username / password, do you encode the string to base64 like when calling jira Cloud?

Yes, BASE64 encoding is required for server version also.

You can refer this -

I would like to ask you for a small favour. Since I do not have access to a Jira Server, would you be so kind to test if my script works with Jira Server too? It can be installed in Chrome / Opera / Firefox from:

I think you might like it.

I can try it on Monday on test instance.



If you try the iPlugin script, you can best use Chrome; the webstore now publishes the latest version 5.0. It can be installed here:


I could test it on Jira Cloud. It would be great to hear if it also works on Jira Server.

@M KTwo issues so far,

1. Window is too much transparent, and if you site is blue it become difficult to read text in plugin dialog.

2. When I entered site details, and pressed `LOGIN` button, nothing happen. Neither there was indicator of processing nor any action happen even after 2-3 minutes. I have triple checked credentials I was using. Also there was not network request, so it seems like some JS issue.


I hope this help.

That is strange indeed. The calls to Jira are made by the background page. You can open it by extensions > iPlugin > background page. It should show why the call fails. 


Also, if you could provide me with a test account on some Jira server accessible from outside, I could test it myself. If that is not possible, I understand.


PS If you try the same with Jira Cloud it should work fine with emai / API Token login.
