Why isn't my Jira priority field being set via SNS and Lambda?

[Gustaf Matsson]

Hi,

I’m integrating AWS GuardDuty with Jira Service Management. My Lambda function maps GuardDuty severity (1–8) to Jira priority codes (P1–P4) and sends an SNS message with a payload that includes a “Priority” field. However, Jira doesn’t seem to pick up or display this priority. Everything else works fine, creates alerts with description etc.

Here’s my simplified mapping function:

 function mapSeverityToPriority(severity: number): string { 

  if (severity < 4) return "P4"; 
  else if (severity < 6) return "P3"; 
  else if (severity < 8) return "P2"; 
  else return "P1"; 

} 


Payload: { 
  "Priority": jiraPriority, 
  // ...other fields... 
} 

Could it be a configuration issue on the Jira side, or is there something else I’m missing in the payload format?

Thanks in advance for your help!

Hi @Gustaf Matsson 

Welcome to the community.

What are you trying to create in the Jira side a work item (issue) or an alert?

An alert in jira service management.
