# AnkiConnect

The AnkiConnect plugin enables external applications such as [Yomichan](https://foosoft.net/projects/yomichan/) to communicate with
[Anki](https://apps.ankiweb.net/) over a network interface. This software makes it possible to execute queries against
the user's card deck, automatically create new vocabulary and Kanji flash cards, and more. AnkiConnect is compatible
with the latest stable (2.1.x) releases of Anki; older versions (2.0.x and below) are no longer supported.

## Installation

The installation process is similar to that of other Anki plugins and can be accomplished in three steps:

1.  Open the `Install Add-on` dialog by selecting `Tools` | `Add-ons` | `Browse & Install` in Anki.
2.  Input [2055492159](https://ankiweb.net/shared/info/2055492159) into the text box labeled `Code` and press the `OK` button to proceed.
3.  Restart Anki when prompted to do so in order to complete the installation of AnkiConnect.

Anki must be kept running in the background in order for other applications to be able to use AnkiConnect. You can
verify that AnkiConnect is running at any time by accessing [localhost:8765](http://localhost:8765) in your browser. If
the server is running, you should see the message `AnkiConnect v.6` displayed in your browser window.

### Notes for Windows Users

Windows users may see a firewall nag dialog box appear on Anki startup. This occurs because AnkiConnect hosts a local
server in order to enable other applications to connect to it. The host application, Anki, must be unblocked for this
plugin to function correctly.

### Notes for Mac OS X Users

Starting with [Mac OS X Mavericks](https://en.wikipedia.org/wiki/OS_X_Mavericks), a feature named *App Nap* has been
introduced to the operating system. This feature causes certain applications which are open (but not visible) to be
placed in a suspended state. As this behavior causes AnkiConnect to stop working while you have another window in the
foreground, App Nap should be disabled for Anki:

1.  Start the Terminal application.
2.  Execute the following commands in the terminal window:
    ```
    defaults write net.ankiweb.dtop NSAppSleepDisabled -bool true
    defaults write net.ichi2.anki NSAppSleepDisabled -bool true
    defaults write org.qt-project.Qt.QtWebEngineCore NSAppSleepDisabled -bool true
    ```
3.  Restart Anki.

## Application Interface for Developers

AnkiConnect exposes Anki features to external applications via an easy to use
[RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer) API. After it is installed, this plugin will
initialize a minimal HTTP sever running on port 8765 every time Anki executes. Other applications (including browser
extensions) can then communicate with it via HTTP POST requests.

By default, AnkiConnect will only bind the HTTP server to the `127.0.0.1` IP address, so that you will only be able to
access it from the same host on which it is running. If you need to access it over a network, you can set the
environment variable `ANKICONNECT_BIND_ADDRESS` to change the binding address. For example, you can set it to `0.0.0.0`
in order to bind it to all network interfaces on your host.

### Sample Invocation

Every request consists of a JSON-encoded object containing an `action`, a `version`, contextual `params`, and a `key`
value used for authentication (which is optional and can be omitted by default). AnkiConnect will respond with an object
containing two fields: `result` and `error`. The `result` field contains the return value of the executed API, and the
`error` field is a description of any exception thrown during API execution (the value `null` is used if execution
completed successfully).

*Sample successful response*:
```json
{"result": ["Default", "Filtered Deck 1"], "error": null}
```

*Samples of failed responses*:
```json
{"result": null, "error": "unsupported action"}
```
```json
{"result": null, "error": "guiBrowse() got an unexpected keyword argument 'foobar'"}
```

For compatibility with clients designed to work with older versions of AnkiConnect, failing to provide a `version` field
in the request will make the version default to 4. Furthermore, when the provided version is level 4 or below, the API
response will only contain the value of the `result`; no `error` field is available for error handling.

You can use whatever language or tool you like to issue request to AnkiConnect, but a couple of simple examples are
included below as reference.

#### Curl

```bash
curl localhost:8765 -X POST -d "{\"action\": \"deckNames\", \"version\": 6}"
```

#### Python

```python
import json
import urllib.request

def request(action, **params):
    return {'action': action, 'params': params, 'version': 6}

def invoke(action, **params):
    requestJson = json.dumps(request(action, **params)).encode('utf-8')
    response = json.load(urllib.request.urlopen(urllib.request.Request('http://localhost:8765', requestJson)))
    if len(response) != 2:
        raise Exception('response has an unexpected number of fields')
    if 'error' not in response:
        raise Exception('response is missing required error field')
    if 'result' not in response:
        raise Exception('response is missing required result field')
    if response['error'] is not None:
        raise Exception(response['error'])
    return response['result']

invoke('createDeck', deck='test1')
result = invoke('deckNames')
print('got list of decks: {}'.format(result))
```

#### JavaScript

```javascript
function invoke(action, version, params={}) {
    return new Promise((resolve, reject) => {
        const xhr = new XMLHttpRequest();
        xhr.addEventListener('error', () => reject('failed to issue request'));
        xhr.addEventListener('load', () => {
            try {
                const response = JSON.parse(xhr.responseText);
                if (Object.getOwnPropertyNames(response).length != 2) {
                    throw 'response has an unexpected number of fields';
                }
                if (!response.hasOwnProperty('error')) {
                    throw 'response is missing required error field';
                }
                if (!response.hasOwnProperty('result')) {
                    throw 'response is missing required result field';
                }
                if (response.error) {
                    throw response.error;
                }
                resolve(response.result);
            } catch (e) {
                reject(e);
            }
        });

        xhr.open('POST', 'http://127.0.0.1:8765');
        xhr.send(JSON.stringify({action, version, params}));
    });
}

await invoke('createDeck', {deck: 'test1'});
const result = await invoke('deckNames', 6);
console.log(`got list of decks: ${result}`);
```

### Supported Actions

Below is a comprehensive list of currently supported actions. Note that deprecated APIs will continue to function
despite not being listed on this page as long as your request is labeled with a version number corresponding to when the
API was available for use.

This page currently documents **version 6** of the API. Make sure to include this version number in your requests to
guarantee that your application continues to function properly in the future.

#### Miscellaneous

*   **version**

    Gets the version of the API exposed by this plugin. Currently versions `1` through `6` are defined.

    This should be the first call you make to make sure that your application and AnkiConnect are able to communicate
    properly with each other. New versions of AnkiConnect are backwards compatible; as long as you are using actions
    which are available in the reported AnkiConnect version or earlier, everything should work fine.

    *Sample request*:
    ```json
    {
        "action": "version",
        "version": 6
    }
    ```

    *Sample result*:
    ```json
    {

    {
        "result": true,
        "error": null
    }
    ```

*   **multi**

    Performs multiple actions in one request, returning an array with the response of each action (in the given order).

    *Sample request*:
    ```json
    {
        "action": "multi",
        "version": 6,
        "params": {

#### Notes

*   **addNote**

    Creates a note using the given deck and model, with the provided field values and tags. Returns the identifier of
    the created note created on success, and `null` on failure.

    AnkiConnect can download audio files and embed them in newly created notes. The corresponding `audio` note member is
    optional and can be omitted. If you choose to include it, it should contain a single object or an array of objects
    with mandatory `url` and `filename` fields. The `skipHash` field can be optionally provided to skip the inclusion of
    downloaded files with an MD5 hash that matches the provided value. This is useful for avoiding the saving of error
    pages and stub files. The `fields` member is a list of fields that should play audio when the card is displayed in
    Anki. The `allowDuplicate` member inside `options` group can be set to true to enable adding duplicate cards.
    Normally duplicate cards can not be added and trigger exception. The `duplicateScope` member inside `options` can be
    used to specify the scope for which duplicates are checked. A value of `"deck"` will only check for duplicates in the
    target deck; any other value will check the entire collection.

    *Sample request*:
    ```json
    {
        "action": "addNote",

#### Media

*   **storeMediaFile**

    Stores a file with the specified base64-encoded contents inside the media folder. alternatively you can specify a
    url from where the file shell be downloaded. If both field `data` and `url` are provided, the `data` field will be
    used. To prevent Anki from removing files not used by any cards (e.g. for configuration files), prefix the filename
    with an underscore. These files are still synchronized to AnkiWeb.

    *Sample request*:
    ```json
    {
        "action": "storeMediaFile",
        "version": 6,

    ```

*   **guiAddCards**

    Invokes the *Add Cards* dialog, presets the note using the given deck and model, with the provided field values and tags.
