How can I run custom scripts or automate advanced workflows in Jira Cloud?

[Gabriel Baldwin]

I’m trying to extend Jira Cloud functionality by running custom scripts or advanced automation beyond the built-in rules. I’ve explored native automation features, but they seem limited for my use case. What are the recommended approaches (e.g., ScriptRunner, REST API, or Forge apps) to achieve more complex logic? Also, are there any limitations or best practices I should be aware of?

Hi @Gabriel Baldwin 

@Arkadiusz Wroblewski is providing solid points here.

Another great app I like to suggest is JWME, find this one on the marketplace.

Hello @Gabriel Baldwin 

In Jira Cloud I would split this into a few different paths.

If your requirement is still within normal Jira logic, native Automation is usually the first place to start. For many cases that is already enough.

If you need more advanced custom logic, then for Cloud I would look more at Forge or an external integration using the REST API.

If you are thinking about something like classic server-side scripting from Server/Data Center days, then that is where people often get surprised. Jira Cloud does not work the same way, so tools like ScriptRunner Cloud can help, but they do not have the same depth and freedom as on DC.

1. For small to medium complexity, use Automation.
2. For real custom business logic, look at Forge or an external service.
3. For admin-style scripting, ScriptRunner Cloud may help, but with Cloud limitations compared to DC.
