# API documentation
PluralKit has a basic HTTP REST API for querying and modifying your system.
The root endpoint of the API is `https://api.pluralkit.me/v1/`.

Endpoints will always return all fields, using `null` when a value is missing. On `PATCH` endpoints, you *must* include
all fields, too. Missing fields will be interpreted as `null`, and `null` fields will have their value removed. To
preserve a value, pass the existing value again.

## Authentication
Authentication is done with a simple "system token". You can get your system token by running `pk;token` using the
Discord bot, either in a channel with the bot or in DMs. Then, pass this token in the `Authorization` HTTP header
on requests that require it. Failure to do so on endpoints that require authentication will return a `401 Unauthorized`.

## Models
The following three models (usually represented in JSON format) represent the various objects in PluralKit's API. A `?` after the column type indicates an optional (nullable) parameter.

### System model

|Key|Type|Patchable?|Notes|
|---|---|---|---|
|id|string|No||
|name|string?|Yes|100-character limit.|
|description|string?|Yes|1000-character limit.|
|tag|string?|Yes||
|avatar_url|url?|Yes|Not validated server-side.|
|tz|string?|Yes|Tzdb identifier. Patching with `null` will store `"UTC"`.|
|created|datetime|No||

### Member model

|Key|Type|Patchable?|Notes|
|---|---|---|---|
|id|string|No||
|name|string?|Yes|50-character limit.|
|description|string?|Yes|1000-character limit.|
|color|color?|Yes|6-char hex (eg. `ff7000`), sans `#`.|
|avatar_url|url?|Yes|Not validated server-side.|
|birthday|date?|Yes|ISO-8601 (`YYYY-MM-DD`) format, year of `0001` means hidden year.|
|prefix|string?|Yes||
|suffix|string?|Yes||
|created|datetime|No||

### Switch model

|Key|Type|Notes|
|---|---|---|
|timestamp|datetime||
|members|list of id/Member|Is sometimes in plain ID list form (eg. `GET /s/<id>/switches`), sometimes includes the full Member model (eg. `GET /s/<id>/fronters`).|

### Message model
|Key|Type|Notes|
|---|---|---
|timestamp|datetime||
|id|snowflake|The ID of the message sent by the webhook. Encoded as string for precision reasons.|
|sender|snowflake|The user ID of the account that triggered the proxy. Encoded as string for precision reasons.|
|channel|snowflake|The ID of the channel the message was sent in. Encoded as string for precision reasons.|
|system|full System object|The system that proxied the message.|
|member|full Member object|The member that proxied the message.|
