Hi Martin,

first, let me tell you that the v3 has been heavily worked on and the following applies mainly to the 5.0 (dev) branch of OpenProject.

you can get a look at the required fields for a new work package of a new project using the /api/v3/projects/:identifier/work_packages/form endpoint [1].
It will return a schema that’s also in use by the frontend to distinguish required and optional parameters as well as getting a list of some potential values (e.g., for the status or work package type).
Note that this schema may be highly different for a given project and type due to the way projects and their types can be customized in OpenProject. If you look at the requests from the frontend, you’ll notice requests to /api/v3/work_packages/schemas/<project-id>-<type-id> that returns the appropriate schema for this project and type.

To create a work package in a given project, you ‘simply’ POST the correct values to the endpoint /api/v3/projects/seeded_project/work_packages/. [2]
In the default Task type, the following JSON hash would be acceptable and creates a WP on my local machine:

{
    "subject":"My subject",
    "description": {
        "format": "textile",
        "raw": "My raw @textile@ formatted description. _Bye guys!_"
    },
    "_links": {
        "type": {"href":"/api/v3/types/1"},
        "status":{"href":"/api/v3/statuses/1"},
        "priority":{"href":"/api/v3/priorities/8"}
    }
}

Best regards,
Oliver from OpenProject

Hello,

I have tried to send a HTTP request to my server to create a work packages and have use your example:

POST http://my.domain.com/api/v3/projects/8/work_packages/form?key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx HTTP/1.1
Content-Type: text/json
Accept-Encoding: gzip, deflate
Host: my.domain.com
Content-Length: 334
Expect: 100-continue

{
subject subject“,
”description“: {
”format“: ”textile“,
”raw“: ”My raw textile formatted description. Bye guys!"
},
“_links”: {
“type”: {href,
status,
priority
}
}
————————————————————————————————-

But I get an error:

HTTP/1.1 406 Not Acceptable
Date: Sun, 06 Dec 2015 13:28:58 GMT
Server: Apache/2.4.7 (Ubuntu)
Status: 406 Not Acceptable
Content-Type: application/hal+json; charset=utf-8
Content-Length: 56
Cache-Control: no-cache
X-Request-Id: ebdb9df2-697c-4073-b4d0-fe25a20c6462
X-Runtime: 0.003627

The requested content-type ‘text/json’ is not supported.
————————————————————————————————-

Unfortunately, I’ve not found in any documentation an example of an whole HTTP request for create a workpackage with API v3.
Have anybody a idee, why this is wrong?

Michael

Hello,

same here, I am not able to create any work packages.
Whatever I send, I get:

type:“Error”
errorIdentifier
message internal error has occured."
embedded

I use 5.0.5, apache httpclient
Anyone has a working example?

Thanks. M.

Works now. The correct content type for posting work_packages is:
“Content-Type: application/json”
not “hal+json”.
