# OpenProject API v3
# Group General
This is the current **DRAFT** of the specification for OpenProject APIv3.
Please note that everything in this document might be **subject to change** in a future version of OpenProject. We intend to keep this specification
as accurate as possible, however as long as the APIv3 is not in a stable state it is possible that there are intermediary differences between
this specification and the real implementation. While we try to only specify what we want to keep, it might also happen that parts of this
specification will be replaced **incompatibly** until the APIv3 is considered *stable*.
# Hypermedia

# Formats
TODO: Description and why only JSON
# HAL+JSON
HAL is a simple format that gives a consistent and easy way to hyperlink between resources in your API.
Read more: http://stateless.co/hal_specification.html
**OpenProject API implementation of HAL+JSON format** enriches JSON and introduces a few meta properties:
- `_type` - specifies the type of the resource (e.g.: WorkPackage, Project)
- `_links` - contains all links available for the resource
- `_embedded` - contains all embedded objects
- `_count` - number of records fetched in the response
- `_total` - number of available records
# API response structure
All API responses contain a single HAL+JSON object. Collections are also represented by a single JSON object that itself
contains its members in its `_embedded` section.
## Simple objects
For example:
{
"id": 1,
"name": "My awesome project",
...
"_type": "Project",
"_links": {
"self": { "href": "/projects/1", "title": "My awesome project" },
"update": { "href": "/projects/1", "method": "patch", "title": "Update My awesome project" },
"delete": { "href": "/projects/1", "method": "delete", "title": "Delete My awesome project" }
},
"_embedded": {
...
}
}
## Collection objects
For example:
{
"_links":
{
"self": { href: "/api/v3/projects" }
},
"_type": "Projects",
"_embedded":
{
"projects": [
{
"self": { "href": "/projects/1" }
"_type": "Project",
// ... etc ...
},
{
"self": { "href": "/projects/2" }
"_type": "Project",
// ... etc ...
}
]
}
}
# Authentication
For now the API only supports **session-based authentication**. This means you have to login to OpenProject via
the Web-Interface to be authenticated in the API. This method is well-suited for clients acting within the browser,
like the Angular-Client built into OpenProject.
However for the future we plan to add authentication modes that are more suitable for **external clients** too.
# Allowed HTTP methods
- `GET` - Get a single resource or collection of resources
- `POST` - Create a new resource or perform
- `PATCH` - Update a resource
- `DELETE` - Delete a resource
# Group Basic Objects
# Errors
In case of an error, the API will respond with an apropriate HTTP status code.
For responses with an HTTP status of `4xx` and `5xx` the body will always contain a single error object.
Error objects shall give the client additional details about the cause of an errorneous response.
## General errors
* Error objects have their `_type` set to `Error`
* The `errorIdentifier` serves as a unique (and machine readable) identifier for a specific error cause
* There *may* be multiple possible error identifiers per HTTP status code
* There *may* be multiple possible HTTP status codes per error identifier
* The "List of Error Identifiers" defines the possible mappings between HTTP status and error identifier
* The `message` contains a human readable concise message describing the error
* It *optionally* includes specific information, for example which permission would have been needed to perform an action
* It it localized depending on the users preferences
* It *must not* include HTML or other kind of markup
* Error messages form complete sentences including punctuation
### Example
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:errors:InternalServerError",
"message": "An internal server error occured. This is not your fault."
}
## Embedded error information
Errors might optionally contain embedded objects that contain further information.
### Error details
Under the embedded key `details` there might be an object describing the error more verbosely. For example if the
error affects a specific field, this field could be defined there.
#### Example
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:examples:ExampleError",
"message": "This is an example error.",
"_embedded": {
"details": {
"_type": "ExampleErrorDetailInformation",
"errorneousField": "subject"
}
}
}
### Multiple error objects
To ease implementation of basic clients it is guaranteed that the response body always only contains a single error object.
However it is allowed that an error object *embeds* other error objects under the key `errors`, thereby aggregating them.
The `errorIdentifier` of such an object is always `urn:openproject-org:api:v3:errors:MultipleErrors`. The message can either describe one of the
embedded errors or simply state that multiple errors occured.
#### Example
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:errors:MultipleErrors",
"message": "Multiple fields violated their constraints.",
"_embedded": {
"errors": [
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:errors:PropertyConstraintViolation",
"...": "..."
},
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:errors:PropertyConstraintViolation",
"...": "..."
}
]
}
}
## List of Error Identifiers
* `urn:openproject-org:api:v3:errors:InvalidRenderContext` (**HTTP 400**) - The client specified a rendering context that does not exist
* `urn:openproject-org:api:v3:errors:MissingPermission` (**HTTP 401** / **HTTP 403**) - The client does not have the needed permissions to perform the requested action
* `urn:openproject-org:api:v3:errors:NotFound` (**HTTP 404**) - Default for HTTP 404 when no further information is available
* `urn:openproject-org:api:v3:errors:UpdateConflict` (**HTTP 409**) - The resource changed between GET-ing it and performing an update on it
* `urn:openproject-org:api:v3:errors:PropertyIsReadOnly` (**HTTP 422**) - The client tried to set or change a property that is not writable
* `urn:openproject-org:api:v3:errors:PropertyConstraintViolation` (**HTTP 422**) - The client tried to set a property to an invalid value
* `urn:openproject-org:api:v3:errors:InternalServerError` (**HTTP 500**) - Default for HTTP 500 when no further information is available
* `urn:openproject-org:api:v3:errors:MultipleErrors` - Multiple errors occured. See the embedded `errors` array for more details.
# Formatable Text
OpenProject supports text formatting in Textile. Other text formats *may* be introduced in the future.
Properties that contain formatable text have a special representation in this API. In this specification their
type is indicated as `Formatable`. Their representation contains the following properties:
| Property | Description | Type | Example | Supported operations |
|:--------:| -------------------------------------------------- | ------ | ---------------------------------- | -------------------- |
| format | Indicates the formatting language of the raw text | String | textile | READ |
| raw | The raw text, as entered by the user | String | `I *am* formatted!` | READ / WRITE |
| html | The text converted to HTML according to the format | String | `I <strong>am</strong> formatted!` | READ |
`format` can as of today have one of the following values:
* `plain` - no formatting at all
* `textile` - formatting using Textile
More formats might be added in the future.
Note that `raw` is the only property supporting the **write** operation. A property of type *Formatable* that
is marked as **read and write**, will only accept changes to the `raw` property. Changes to `format` and `html` will be **silently ignored**.
It is thus sufficient to solely provide the `raw` property for changes.
If the *Formatable* is marked as **read only**, the `raw` attribute also becomes **read only**.
#### Example
{
"format": "textile",
"raw": "I *am* formatted!",
"html": "I <strong>am</strong> formatted!"
}

# Group Previewing
Throughout OpenProject textile is used to support formatting of user input.
Using the apropriate rendering endpoint it is possible to render custom textile inputs into HTML and thus
receive a preview of the rendered textile.
The request to the endpoint should have a MIME-Type of `text/plain`.
The request body is the actual textile string that shall be rendered as HTML string.
## Textile [/render/textile{?context}]
+ Model
+ Body
<p>Hello world! <a href="http://example.com">This</a> <strong>is</strong> textile!</p>
## Preview Textile document [POST]
+ Parameters
+ context (optional, string, `/api/v3/work_packages/42`)
API-Link to the context in which the rendering occurs, for example a specific work package.
If left out only context-agnostic rendering takes place.
Please note that OpenProject features textile-extensions that can only work given a context (e.g. display attached images).
**Supported contexts:**
* `/api/v3/work_packages/{id}` - an existing work package
+ Request (text/plain)
Hello world! "This":http://example.com *is* textile!
+ Response 200 (text/html)
[Textile][]
+ Response 400 (application/json)
Returned if the context passed by the client is not valid (e.g. unknown).
Note that this response will also occur when the requesting user
is not allowed to see the context resource (e.g. limited work package visibility).
+ Body
{
"_type": "Error",
"errorIdentifier": "urn:openproject-org:api:v3:errors:InvalidRenderContext",
"message": "Could not render textile string in the given context."

[WorkPackage][]
## Edit WorkPackage [PATCH]
When calling this endpoint the client provides a single object, containing the properties and links that it wants to change, in the body.
Note that it is only allowed to provide properties or links supporting the **write** operation.
Additionally to the fields the client wants to change, it is mandatory to provide:
* The `_type` which should as of now always be `WorkPackage`
* The value of `lockVersion` which was received by the `GET` request this change originates from.
The value of `lockVersion` is used to implement [optimistic locking](http://en.wikipedia.org/wiki/Optimistic_concurrency_control).
+ Parameters
+ id (required, integer, `1`) ... Work package id
+ Request (application/json)
{
"_type": "WorkPackage",

"message": "You are not allowed to edit the content of the work package."
}
+ Response 409 (application/hal+json)
Returned if the resource was changed since the client requested it. This is determined using the `lockVersion` property.

}
+ Response 422 (application/hal+json)
Returned if:
* the client tries to modify a read-only property
* a constraint for a property was violated
