They are not the same as direct messages and they are not `Status`es, even though they have a lot in common. + +## Why Chats? + +There are no 'visibility levels' in ActivityPub, their definition is purely a Mastodon convention. Direct Messaging between users on the fediverse has mostly been modeled by using ActivityPub addressing following Mastodon conventions on normal `Note` objects. In this case, a 'direct message' would be a message that has no followers addressed and also does not address the special public actor, but just the recipients in the `to` field. It would still be a `Note` and is presented with other `Note`s as a `Status` in the API. + +This is an awkward setup for a few reasons: + +- As DMs generally still follow the usual `Status` conventions, it is easy to accidentally pull somebody into a DM thread by mentioning them. (e.g. "I hate @badguy so much") +- It is possible to go from a publicly addressed `Status` to a DM reply, back to public, then to a 'followers only' reply, and so on. This can be become very confusing, as it is unclear which user can see which part of the conversation. +- The standard `Status` format of implicit addressing also leads to rather ugly results if you try to display the messages as a chat, because all the recipients are always mentioned by name in the message. +- As direct messages are posted with the same api call (and usually same frontend component) as public messages, accidentally making a public message private or vice versa can happen easily. Client bugs can also lead to this, accidentally making private messages public. + +As a measure to improve this situation, the `Conversation` concept and related Pleroma extensions were introduced. While it made it possible to work around a few of the issues, many of the problems remained and it didn't see much adoption because it was too complicated to use correctly. + +## Chats explained +For this reasons, Chats are a new and different entity, both in the API as well as in ActivityPub. A quick overview: + +- Chats are meant to represent an instant message conversation between two actors. For now these are only 1-on-1 conversations, but the other actor can be a group in the future. +- Chat messages have the ActivityPub type `ChatMessage`. They are not `Note`s. Servers that don't understand them will just drop them. +- The only addressing allowed in `ChatMessage`s is one single ActivityPub actor in the `to` field. +- There's always only one Chat between two actors. If you start chatting with someone and later start a 'new' Chat, the old Chat will be continued. +- `ChatMessage`s are posted with a different api, making it very hard to accidentally send a message to the wrong person. +- `ChatMessage`s don't show up in the existing timelines. +- Chats can never go from private to public. They are always private between the two actors. + +## Caveats + +- Chats are NOT E2E encrypted (yet). Security is still the same as email. + +## API + +In general, the way to send a `ChatMessage` is to first create a `Chat`, then post a message to that `Chat`. `Group`s will later be supported by making them a sub-type of `Account`. + +This is the overview of using the API. The API is also documented via OpenAPI, so you can view it and play with it by pointing SwaggerUI or a similar OpenAPI tool to `https://yourinstance.tld/api/openapi`. + +### Creating or getting a chat. + +To create or get an existing Chat for a certain recipient (identified by Account ID) +you can call: + +`POST /api/v1/pleroma/chats/by-account-id/{account_id}` + +The account id is the normal FlakeId of the user +``` +POST /api/v1/pleroma/chats/by-account-id/someflakeid +``` + +If you already have the id of a chat, you can also use + +``` +GET /api/v1/pleroma/chats/:id +``` + +There will only ever be ONE Chat for you and a given recipient, so this call +will return the same Chat if you already have one with that user. + +Returned data: + +```json +{ + "account": { + "id": "someflakeid", + "username": "somenick", + ... + }, + "id" : "1", + "unread" : 2, + "last_message" : {...}, // The last message in that chat + "updated_at": "2020-04-21T15:11:46.000Z" +} +``` + +### Marking a chat as read + +To set the `unread` count of a chat to 0, call + +`POST /api/v1/pleroma/chats/:id/read` + +Returned data: + +```json +{ + "account": { + "id": "someflakeid", + "username": "somenick", + ... + }, + "id" : "1", + "unread" : 0, + "updated_at": "2020-04-21T15:11:46.000Z" +} +``` + + +### Getting a list of Chats + +`GET /api/v1/pleroma/chats` + +This will return a list of chats that you have been involved in, sorted by their +last update (so new chats will be at the top). + +Returned data: + +```json +[ + { + "account": { + "id": "someflakeid", + "username": "somenick", + ... + }, + "id" : "1", + "unread" : 2, + "last_message" : {...}, // The last message in that chat + "updated_at": "2020-04-21T15:11:46.000Z" + } +] +``` + +The recipient of messages that are sent to this chat is given by their AP ID. +The usual pagination options are implemented. + +### Getting the messages for a Chat + +For a given Chat id, you can get the associated messages with + +`GET /api/v1/pleroma/chats/{id}/messages` + +This will return all messages, sorted by most recent to least recent.
