make form public for anonymous users

[UTD]

I tried to make the form public using the scheme recommended on this page :  Allow anonymous access to projects

 I configured the settings on the creation of tickets as open to public.

But I have a problem with the link that must be shared with the public. Where do I have to copy it to share it?

Please can you help me?

Have a look at https://docs.atlassian.com/jira/REST/server/ which lists all the REST calls you can make.

From memory, there isn't one for "fields associated with project", because it's not a simple question.  Do you mean by field context?  What if the field configuration hides it?  What if there are several contexts with different options?  What if it's valid, but not on screen, or on a screen but hidden?  Finally, fields:project is not how it works, it's fields:issuetype-in-project
