How can I make fields required when creating forms

[Alex John]

Hello - I am trying to make it so that my individual teams can customize the way tickets are created for their projects by having them create required fields for internal customers when making tickets (such as due date).  I don't want these to be optional - if someone makes a certain type of ticket they will have to fill out all fields associated.  Is this possible with forms, or should I be doing this some other way?

Correct. In addition, Atlassian Support discourages direct database modification as this can cause corruption.

Not everything can be changed using the API. Changing the JIRA license is one example.

Since this is a staging instance we are OK with making direct changes to the database and are looking to see if anyone else has done this and what suggestions they might have.

Pretty much every admin really discourages working directly in the database. Have you tried using the REST API?
