Is it possible to create subtasks on an existing issues using JSON

We have teams that have created a ton of parent issues and now want to create all the subtasks that need to be associated to them.  I know CSV will not work can they use JSON?

Yes, you can. I just need to provide a parent field when creating the issue through JSON, as per the doc



Sorry I will need to re-clarify.  They are wanting to use the JSON importer as per to import just subtasks for their issues

Based on comment from Przemyslaw Borkowski on the the link provided over you can use the subtasks object for this, but in your case (only import of subtasks) you are looking the parent id described under Creating sub-tasks as per

CSV cannot import sub-tasks unless you import the parent at the same time.  This team ONLY wants to import sub-tasks since they have ALL the parents already created.  They asked if they can use JSON but we are unsure how to assist them as we have never used the JSON importer before.

Not really, the JSON just offers a more complete option to import data, having more options do described data, but has the same limitations as the CSV importer. I think your best option here would be create your own script to read the data from the CSV ou JSON file you have and create the issues with the JIRA API.

Ahh ok.. What will happen if you export all parents to csv, then add the new subtasks to the same file, and re-import?

Thank you Teilor Soares. I will let me know. Alexander that is one way they could have done it but they were not interested initially but they may be inclined to now.

I don't know about JSON, but importing subtasks to existing issue using CSV works for me. Just make sure that the value of Parent ID is the same as External Issue ID of the existing issue. You can add External Issue ID if the issue doesn't have one and delete it later after finishing the import
