Differences in Mastodon API responses from vanilla Mastodon

A Pleroma instance can be identified by " (compatible; Pleroma )" present in version field in response from /api/v1/instance

Flake IDs

Pleroma uses 128-bit ids as opposed to Mastodon's 64 bits. However just like Mastodon's ids they are lexically sortable strings

Timelines

Adding the parameter with_muted=true to the timeline queries will also return activities by muted (not by blocked!) users. Adding the parameter exclude_visibilities to the timeline queries will exclude the statuses with the given visibilities. The parameter accepts an array of visibility types (public, unlisted, private, direct), e.g., exclude_visibilities[]=direct&exclude_visibilities[]=private. Adding the parameter reply_visibility to the public and home timelines queries will filter replies. Possible values: without parameter (default) shows all replies, following - replies directed to you or users you follow, self - replies directed to you.

Statuses

  • visibility: has an additional possible value list

Has these additional fields under the pleroma object:

  • local: true if the post was made on the local instance
  • conversation_id: the ID of the AP context the status is associated with (if any)
  • direct_conversation_id: the ID of the Mastodon direct message conversation the status is associated with (if any)
  • in_reply_to_account_acct: the acct property of User entity for replied user (if any)
  • content: a map consisting of alternate representations of the content property with the key being it's mimetype. Currently the only alternate representation supported is text/plain
  • spoiler_text: a map consisting of alternate representations of the spoiler_text property with the key being it's mimetype. Currently the only alternate representation supported is text/plain
  • expires_at: a datetime (iso8601) that states when the post will expire (be deleted automatically), or empty if the post won't expire
  • thread_muted: true if the thread the post belongs to is muted
  • emoji_reactions: A list with emoji / reaction maps. The format is {name: "☕", count: 1, me: true}. Contains no information about the reacting users, for that use the /statuses/:id/reactions endpoint.
  • parent_visible: If the parent of this post is visible to the user or not.

Media Attachments

Has these additional fields under the pleroma object:

  • mime_type: mime type of the attachment.

Attachment cap

Some apps operate under the assumption that no more than 4 attachments can be returned or uploaded. Pleroma however does not enforce any limits on attachment count neither when returning the status object nor when posting.

Limitations

Pleroma does not process remote images and therefore cannot include fields such as meta and blurhash. It does not support focal points or aspect ratios. The frontend is expected to handle it.

Accounts

The id parameter can also be the nickname of the user. This only works in these endpoints, not the deeper nested ones for following etc.

  • /api/v1/accounts/:id
  • /api/v1/accounts/:id/statuses

  • to: A list of nicknames (like lain@soykaf.club or lain on the local server) that will be used to determine who is going to be addressed by this post. Using this will disable the implicit addressing by mentioned names in the status body, only the people in the to list will be addressed. The normal rules for for post visibility are not affected by this and will still apply.
  • visibility: string, besides standard MastoAPI values (direct, private, unlisted or public) it can be used to address a List by setting it to list:LIST_ID.

Pleroma Settings Store

Pleroma has mechanism that allows frontends to save blobs of json for each user on the backend. This can be used to save frontend-specific settings for a user that the backend does not need to know about.

The parameter should have a form of {frontend_name: {...}}, with frontend_name identifying your type of client, e.g. pleroma_fe. It will overwrite everything under this property, but will not overwrite other frontend's settings.

This information is returned in the /api/v1/accounts/verify_credentials endpoint.

Not implemented

Pleroma is generally compatible with the Mastodon 2.7.2 API, but some newer features and non-essential features are omitted. These features usually return an HTTP 200 status code, but with an empty response. While they may be added in the future, they are considered low priority.
