# API reference
|
||||||
|
|
||||||
|
Lemmy has two, intertwined APIs:
|
||||||
|
- WebSocket [](Add_link)
|
||||||
|
- [HTTP](http_api.md)
|
||||||
|
|
||||||
|
This page describes concepts that are common to both.

|
<!-- tocstop -->
|
||||||
|
|
||||||
|
## Basic usage
|
||||||
|
|
||||||
|
Request and response strings are in [JSON format](https://www.json.org).
|
||||||
|
|
||||||
|
## Data types
|
||||||
|
|
||||||
|
### Lemmy types
|
||||||
|
|
||||||
|
- [Source tables, that have the columns / fields](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/source.ts)
|
||||||
|
- [Aggregates (for things like scores)](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/aggregates.ts)
|
||||||
|
- [Views - The main lemmy return types](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/views.ts)
|
||||||
|
- [Request Forms / Responses are in this folder](https://github.com/LemmyNet/lemmy-js-client/tree/main/src/interfaces/api)
|
||||||
|
|
||||||
|
### Lower-level types
|
||||||
|
|
||||||
|
- `?` designates an option which may be omitted in requests and not be present in responses. It will be of type ***SomeType***.
|
||||||
|
- `[SomeType]` is a list which contains objects of type ***SomeType***.
|
||||||
|
- Times and dates are timestamp strings in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format. Timestamps will be UTC, your client must do the UTC to local conversion.
|
||||||
|
|
||||||
|
## Default rate limits
|
||||||
|
|
||||||
|
These can be edited in your `lemmy.hjson` file, by copying the relevant section from [defaults.hjson](https://github.com/LemmyNet/lemmy/blob/main/config/defaults.hjson).
|
||||||
|
|
||||||
|
- 3 per hour for signups and community creation.
|
||||||
|
- 6 per hour for image posting.
|
||||||
|
- 6 per 10 minutes for post creation.
|
||||||
|
- 180 actions per minute for post voting and comment creation.
|
||||||
|
|
||||||
|
Everything else is not rate-limited.
|
||||||
|
|
||||||
|
**See also:** [rate limiting for custom front-ends](custom_frontend.md#rate-limiting).

|
|
||||||
|
## WebSocket vs HTTP API
|
||||||
|
Lemmy's HTTP API is almost identical to its WebSocket API:
|
||||||
|
- **WebSocket API** needs `let send = { op: userOperation[op], data: form}` as shown in [the WebSocketAPI specification](add_link)
|
||||||
|
- **HTTP API** needs the form (data) at the top level, an HTTP operation (GET, PUT or POST) and endpoint (at `http(s)://host/api/v2/endpoint`). For example:
|
||||||
|
|
||||||
|
> `POST {username_or_email: X, password: X}`
|
||||||
|
|
||||||
|
For more information, see the [http.ts](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/http.ts) file.
|
||||||
|
|
||||||
|
[The WebSocket API](Add_link) should be regarded as the primary source for the HTTP API since it also provides information about how to form HTTP API calls.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
### TypeScript
|
||||||
|
|
||||||
|
```ts
|
||||||
|
async editComment(form: EditComment): Promise<CommentResponse> {
|
||||||
|
return this.wrapper(HttpType.Put, '/comment', form);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
| Type | URL | Body type | Return type |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| `PUT` | `/comment` | `EditComment` | `CommentResponse` |
|
||||||
|
|
||||||
|
### Curl
|
||||||
|
|
||||||
|
**GET example**
|
||||||
|
|
||||||
|
```
|
||||||
|
curl "http://localhost:8536/api/v2/community/list?sort=Hot"`
|
||||||
|
```
|
||||||
|
|
||||||
|
**POST example**
|
||||||
|
|
||||||
|
```
|
||||||
|
curl -i -H \
|
||||||
|
"Content-Type: application/json" \
|
||||||
|
-X POST \
|
||||||
|
-d '{
|
||||||
|
"comment_id": 374,
|
||||||
|
"score": 1,
|
||||||
|
"auth": eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6MiwiaXNzIjoidGVzdC5sZW1teS5tbCJ9.P77RX_kpz1a_geY5eCp29sl_5mAm-k27Cwnk8JcIZJk
|
||||||
|
}' \
|
||||||
|
http://localhost:8536/api/v2/comment/like
|
||||||
|
```
|
||||||
|
|
||||||
|
## HTTP API exclusive features
|
||||||
|
|
||||||
|
These features cannot be accessed from the WebSocket API:
|
||||||
|
- [RSS/Atom feeds](#rss-atom-feeds)
|
||||||
|
- [Images](#images)
|
||||||
|
### RSS/Atom feeds
|
||||||
|
|
||||||
|
- All - `/feeds/all.xml?sort=Hot`
|
||||||
|
- Community - `/feeds/c/community-name.xml?sort=Hot`
|
||||||
|
- User - `/feeds/u/user-name.xml?sort=Hot`
|
||||||
|
|
||||||
|
### Images
|
||||||
|
|
||||||
|
Lemmy forwards image requests to a locally running Pictrs.
|
||||||
|
|
||||||
|
`GET /pictrs/image/{filename}?format={webp, jpg, ...}&thumbnail={96}`
|
||||||
|
|
||||||
|
*Format and thumbnail are optional.*
|
||||||
|
|
||||||
|
#### Create (request)
|
||||||
|
|
||||||
|
Uploaded content must be valid multipart/form-data with an image array located within the images[] key.
|
||||||
|
|
||||||
|
`POST /pictrs/image`
|
||||||
|
|
||||||
|
#### Create (response)
|
||||||
|
|
||||||
|
```
|
||||||
|
{
|
||||||
|
"files": [
|
||||||
|
{
|
||||||
|
"delete_token": "{token}",
|
||||||
|
"file": "{file}.jpg"
|
||||||
|
}
|
||||||
|
],
|
||||||
|
"msg": "ok"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Delete
|
||||||
|
|
||||||
|
`GET /pictrs/image/delete/{delete_token}/{file}`
|
||||||
|
|
||||||
|
|
||||||

## Basic usage
|
|
||||||
|
|
||||||
Request and response strings are in [JSON format](https://www.json.org).
|
|
||||||
|
|
||||||
## Data types
|
|
||||||
|
|
||||||
### Lemmy Types
|
|
||||||
|
|
||||||
- [Source tables, that have the columns / fields](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/source.ts)
|
|
||||||
- [Aggregates (for things like scores)](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/aggregates.ts)
|
|
||||||
- [Views - The main lemmy return types](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/interfaces/views.ts)
|
|
||||||
- [Request Forms / Responses are in this folder](https://github.com/LemmyNet/lemmy-js-client/tree/main/src/interfaces/api)
|
|
||||||
|
|
||||||
### Lower-level types
|
|
||||||
|
|
||||||
- `?` designates an option which may be omitted in requests and not be present in responses. It will be of type ***SomeType***.
|
|
||||||
- `[SomeType]` is a list which contains objects of type ***SomeType***.
|
|
||||||
- The fields published, and updated are timestamp strings in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format. Timestamps will be UTC, your client must do the UTC -> local conversion.
|
|
||||||
|
|
||||||
### Sort Types
|
|
||||||
|
|
||||||
These go wherever there is a `sort` field. The available sort types are:
|
|
||||||
|
|
||||||
- `Active` - the hottest posts/communities, depending on votes, and newest comment publish date.
|
|
||||||
- `Hot` - the hottest posts/communities, depending on votes and publish date.
|
|
||||||
- `New` - the newest posts/communities
|
|
||||||
- `TopDay` - the most upvoted posts/communities of the current day.
|
|
||||||
- `TopWeek` - the most upvoted posts/communities of the current week.
|
|
||||||
- `TopMonth` - the most upvoted posts/communities of the current month.
|
|
||||||
- `TopYear` - the most upvoted posts/communities of the current year.
|
|
||||||
- `TopAll` - the most upvoted posts/communities on the current instance.
|
|
||||||
|
|
||||||
## Default Rate limits
|
|
||||||
|
|
||||||
These can be edited in your `lemmy.hjson` file, by copying the relevant section from [defaults.hjson](https://github.com/LemmyNet/lemmy/blob/main/config/defaults.hjson).
|
|
||||||
|
|
||||||
- 3 per hour for signups and community creation.
|
|
||||||
- 6 per hour for image posting.
|
|
||||||
- 6 per 10 minutes for post creation.
|
|
||||||
- 180 actions per minute for post voting and comment creation.
|
|
||||||
-
|
|
||||||
- Everything else is not rate-limited.
|
|
||||||
|
|
||||||
## Errors
|
|
||||||
|
|
||||||
```rust
|
|
||||||
{
|
|
||||||
op: String,
|
|
||||||
message: String,
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Undoing actions
|
|
||||||
|
|
||||||
Whenever you see a `deleted: bool`, `removed: bool`, `read: bool`, `locked: bool`, etc, you can undo this action by sending `false`:
|
|
||||||
|
|
||||||
```ts
|
|
||||||
// Un-delete a post
|
|
||||||
let form: DeletePost = {
|
|
||||||
post_id: ...
|
|
||||||
deleted: false,
|
|
||||||
auth: ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## Websocket vs HTTP
|
|
||||||
|
|
||||||
- Below are the websocket JSON requests / responses. For HTTP, ignore all fields except those inside `data`.
|
|
||||||
- For example, an http login will be a `POST` `{username_or_email: X, password: X}`
|
|
||||||
|
|
||||||
## HTTP
|
|
||||||
|
|
||||||
For documentation of the HTTP API, look at the [http.ts file in lemmy-js-client](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/http.ts).
|
|
||||||
|
|
||||||
Endpoints are at `http(s)://host/api/v2/endpoint`
|
|
||||||
|
|
||||||
### Example
|
|
||||||
|
|
||||||
```ts
|
|
||||||
async editComment(form: EditComment): Promise<CommentResponse> {
|
|
||||||
return this.wrapper(HttpType.Put, '/comment', form);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
| Type | url | Body Type | Return Type |
|
|
||||||
| --- | --- | --- | --- |
|
|
||||||
| `PUT` | `/comment` | `EditComment` | `CommentResponse` |
|
|
||||||
|
|
||||||
### Testing with Curl
|
|
||||||
|
|
||||||
#### Get Example
|
|
||||||
|
|
||||||
`curl "http://localhost:8536/api/v2/community/list?sort=Hot"`
|
|
||||||
|
|
||||||
#### Post Example
|
|
||||||
|
|
||||||
```
|
|
||||||
curl -i -H \
|
|
||||||
"Content-Type: application/json" \
|
|
||||||
-X POST \
|
|
||||||
-d '{
|
|
||||||
"comment_id": X,
|
|
||||||
"score": X,
|
|
||||||
"auth": X
|
|
||||||
}' \
|
|
||||||
http://localhost:8536/api/v2/comment/like
|
|
||||||
```
|
|
||||||
|
|
||||||
## Websocket
|
|
||||||
|
|
||||||
The websocket commands are in [websocket.ts](https://github.com/LemmyNet/lemmy-js-client/blob/main/src/websocket.ts), and exactly match the http commands,
|
|
||||||
|
|
||||||
Connect to <code>ws://***host***/api/v2/ws</code> to get started.
|
|
||||||
|
|
||||||
If the ***`host`*** supports secure connections, you can use <code>wss://***host***/api/v1/ws</code>.
|
|
||||||
|
|
||||||
To receive websocket messages, you must join a room / context. The four available are:
|
|
||||||
|
|
||||||
- UserJoin. Receives replies, private messages, etc.
|
|
||||||
- PostJoin. Receives new comments on a post.
|
|
||||||
- CommunityJoin. Receives front page / community posts.
|
|
||||||
- ModJoin. Receives community moderator updates like reports.
|
|
||||||
|
|
||||||
### Testing with Websocat
|
|
||||||
|
|
||||||
[Websocat link](https://github.com/vi/websocat)
|
|
||||||
|
|
||||||
`websocat ws://127.0.0.1:8536/api/v2/ws -nt`
|
|
||||||
|
|
||||||
A simple test command:
|
|
||||||
`{"op": "ListCategories", "data": {}}`
|
|
||||||
|
|
||||||
### Testing with the WebSocket JavaScript API
|
|
||||||
|
|
||||||
[WebSocket JavaScript API](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)
|
|
||||||
|
|
||||||
```javascript
|
|
||||||
var ws = new WebSocket("ws://" + host + "/api/v2/ws");
|
|
||||||
ws.onopen = function () {
|
|
||||||
console.log("Connection succeed!");
|
|
||||||
ws.send(JSON.stringify({
|
|
||||||
op: "ListCategories",
|
|
||||||
data: {}
|
|
||||||
}));
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
