Rest APIs for Export and Import of Jira issues

[Rutvi Sukhadia]

We want to explore and use the Jira issues export and import functionalities provided by the Jira Importers plugin through Rest APIs to avoid manual efforts.

I checked the comments on the following post and tested the same with our Jira instances:

https://community.atlassian.com/t5/Jira-Software-questions/REST-Import-API/qaq-p/433878

We can export the issues one by one via the following REST API from our Jira server instance, but the same is not working for the Jira cloud

GET {{jiraURL}}/si/com.atlassian.jira.plugins.jira-importers-plugin:issue-json/{{issueKey}}/{{issueKey}}.json

Could someone please suggest if any additional setting is required to enable the JSON export for Jira cloud?

We can import the Jira issues by providing the issue details JSON request body (format being same as mentioned in the documentation) using the following REST API:

POST {{jiraURL}}/rest/jira-importers-plugin/1.0/importer/json

However, I could not find these Rest APIs documented anywhere else than the above community post. Can we use these rest endpoints for production migrations or are these private APIs? Can we get the reference documentation for the same?

Thanks

Any updates on this?
