Empty and Error Responses from Jira Cloud Basic Auth with API Token

[Eric Stephenson]

I am working on changing our apps to use basic auth with an API Token per Jira's deprecation notice, but GET create meta returns an empty array:

curl -D- \
   -u fred@example.com:freds_api_token \
   -X GET \
   -H "Content-Type: application/json" \
   https://your-domain.atlassian.net/rest/api/3/issue/createmeta

# =>  {"expand":"projects","projects":[]}

and a POST request to create an issue returns an error response similar to when the user does not have admin permission to edit the screen:

"Field <field name> cannot be set. It is not on the appropriate screen, or unknown."

However, the supplied user name definitely has admin permission.

I have also tried this with the Base64 encoded user:token in the Authorization header

but I get the same responses.

Any help would be much appreciated.

For anyone who lands here, there is an important caveat to Jira API Tokens:  they will have the same permission level as the user who creates them.

I just ran successful curls to our Endpoint using an API Token created by an admin user, AND the user's full email address.

Issue resolved.
