ESi authentication with Postman

[Kalo_en_Chasteaux]

Greetings:

I’m trying to call the EVE ESI from [Postman](https://www.postman.com]. I have successfully configured OAuth2 and can get tokens. The application is configured to support all scopes (which are filled out in my token request). However, when I make a call to a secure endpoint, I always get a 403 error returning a {"error": "authentication failure"}

Note that this is a 403 (Forbidden), not a 401 ( Unauthorized) error code. It seems reminiscent of the issue being described here

Has anyone successfully configured ESI authentication to call the API from Postman?

Many thanks!

Authentication works but cant use token in ESI call

Hi, I’m returning to eve after a long pause and all my own tools are not working anymore so I thought I jump onto the swagger train as it’s a nice challenge. I have gotten my authentication to work with the code challenge and all the jazz and I also successfully get the token and I can verify and grab the data in that token with no issue. Now I am trying to call my first ESI call. I’ve created implementations for a status call and a character skills call just to make sure I can do unauthorized…

That’s your issue, most likely. Don’t do that. Only request scopes you really need.

Authorization failure when token is too long

Yeah but

You should really read the issue…

[Eloken_Toralen]

Yeah you are probably right. Ignore previous comment.

Thank you, this indeed seems to be the issue. To be clear, I can configure all scopes on the application in the developper portal, but then only specify the scopes I need when I request the token.
