Issue Summary

It would be wonderful if Jira Rest API could have an endpoint allowing you to import JSON files that are loaded in the JSON Import Function implemented in the User interface.

With this feature, we could save a lot of effort if we load these files and everything gets created instead of using the individual REST API to create custom fields, Issue Types, Issues, etc.

Being said that, we can focus efforts on creating and validating a single input: the JSON file, instead of validating every single endpoint. 

Expected Results

Create rest API endpoint like: /rest/api/3/issues/import/json.... in order to import JSON files compatible with this KB https://confluence.atlassian.com/adminjiracloud/importing-data-from-json-776636779.html

Actual Results

NA

Workaround

Use the User Interface to import JSON files.
