REST API for issue fields maximum character length

[Victor Cheung]

Hello,

How can I determine the maximum characters length for all (text based) fields on my issue type using REST API?  (How can I determine the maximum character length for a text field programmatically?)

Use case:  I want to preempt the JIRA issue update/creation errors due to exceeding the maximum character length.

I am using JIRA 8.5.0 and I have looked at the JIRA 8.5.0 REST API but didn't see anything.

Thanks!

Hi Victor,

I don't think there is public API for this, but if you open the advanced properties page you can find that it fetches the configuration via REST at {{ baseurl }}/rest/api/latest/application-properties/advanced-settings

This returns json with configuration including the text character limit:

{
"defaultValue": "32767",
"desc": "The maximum number of characters to be entered for a single field. Affects Description, Environment, Comments and Text custom fields. 0 means unlimited.",
"id": "jira.text.field.character.limit",
"key": "jira.text.field.character.limit",
"name": "jira.text.field.character.limit",
"type": "uint",
"value": "2393740"
},

If there is not a better method, I would go down this road and grep the value from that json.

Fingers crossed for a more "programmatic" way though, just an idea.

Thank you, Radek!  This is what I was looking for!  

Cheers!

Hi Victor,
This is an advanced setting in the Jira UI. Check out the jira.text.field.character.limit per Atlassian's Configuring advanced settings page. Cheers!

Hi Joshua, not sure how else to say it, but please read the title of my post.  Please re-read my entire post content carefully.  Your reply is something I already know and it is not the answer I am seeking.  But as they say -- thanks for coming out!
