Create issue and apply template with Jira REST API

You can use Jira REST API to Create issue and add to the body of the request’s issue.templates.automation property.

{ 
  "properties": [
    { "key": "issue.templates.automation", 
      "value": { 
        "applyTemplate": "TEMPLATE-1"
      }
    }
  ]
}

Provide:

• Project
• Issue type
• Summary
• other required fields from your issue type

Example

TEMPLATE-1 is an issue key of your template. As soon as you click Create, TEMPLATE-1 will be applied to the issue. It may overwrite provided summary based on your template’s scope.

Use the example below to create similar configuration.

{
    "fields": {
        "project": {
            "key": "JSA"
        },
        "summary": "Create issue from Postman",
        "issuetype": {
            "id": "10000"
        }
    },
    "properties": [
            {
                "key": "issue.templates.automation",
                "value": {
                "applyTemplate": "TEMPLATE-1",
                "variables": {
                    "MyDynamicVariable": "abc"
                }
            }
            }
    ]
}

You can also provide values for dynamic variables defined in your primary template as shown above.
