Redmine

I have been trying to batch import multiple issues to Redmine without success. Initially I tried redmine_importer but this does not seem to work with v2.3

I am now experimenting with the REST api using curl. Following the instructions here I can post issues individually but cannot understand how I can import a whole load at the same time? I was hoping to just be able to convert an excel file to one big json file and import everything in one go however when I try putting more than one issue in to the file it will only import the last one.

this is the curl command I am using:

curl -v -H "Content-Type: application/json" -X POST --data "@test2.json" -u asami morita localhost/redmine/issues.json

and this is the test2.json file:

{
  "issue": {
  "project_id": 9,
    "subject": "TEST5",
    "notes": "foobar",
    "priority_id": 2
  },
   "issue": {
  "project_id": 9,
    "subject": "TEST6",
    "notes": "barfoo",
    "priority_id": 3
  }

}

Can anybody suggest what I may be doing wrong or a better alternative?

Many thanks
