Cannot retrieve data via Postman via REST API v2 and v3

[Deleted user]

Hello,

I have download the Open API specs of REST API and REST API v2 for Jira Cloud. I generated API token and by using Postman tried to retrieve dynamic webhook data.

I used Basic Auth for that. username is email adress and password api token.

With same username and api token,

For REST API v2, I got that response;

{

"errorMessages": [

"Only apps can access this resource."

],

"errors": {}

}

For REST API, I got that response;

{

"message": "Client must be authenticated to access this resource.",

"status-code": 401

}

I plan to use v2 for my work, so I wonder what is missing here.

Thanks
