Hi @Dario B

Thanks for your reply.

I have already seen above URL.That URL contains user name and password.But i am having accessToken(i dont have user name password).i have to add an attachment to jira issue through rest API from my java code.

It should work the same way. You just have to pass the access token in the request header as specified in:

https://developer.atlassian.com/cloud/jira/platform/jira-rest-api-oauth-authentication/

Pass the OAuth access token in the request header, not request body, when making requests: If you pass the OAuth data in the request body, it will return a “400 Bad Request” error for most methods. You must pass the data in the header instead, e.g. “Authorization: Bearer {access_token}“

they have defined the Add attachment API, In that API they need attachment as  multi part form request.but my side i have attachment as input stream how can i convert input stram to multipart and send them.
