[Ruqia Hussain]

Is there anyway to authenticate a user, who is non jira user. Lets consider I have an application where my customer register. I want to allow these registered user of application to access Jira using Jira rest api's. Is there any way to authenticate them ? Yes I am adding their email as an customer in my Jira organization.

Hello @Ruqia Hussain 

Welcome to the Atlassian community.

Only licensed users of the Jira product will be able to authenticate and use the APIs. If you don't want to grant those users product access to Jira then you will have to use an intermediary account that does have product access, and run the APIs using the intermediary user.

I want to give them access of my specific projects. So they can create issue send attachment or comment on issues. So basic they can do this all using jira res api. But how, and which authentication I can use so my customer will be able to do this all. ?

What is intermediary account ? And this can be created ?

If you plan to give them access to your product, do that the same way you would do that for any user. That is the right path.

Using an intermediary account is not the recommended path.

I have not developed an integration to the Jira API from another application so I can't provide the details for how to code the authentication process. I recommend that you review the Atlassian REST API documentation concerning authentication:
