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 sortable strings

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.

Timelines

Adding the parameter with_muted=true to the timeline queries will also return activities by muted (not by blocked!) users.

Statuses

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 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

Attachments

Has these additional fields under the pleroma object:

• mime_type: mime type of the attachment.

Accounts

• /api/v1/accounts/:id: The id parameter can also be the nickname of the user. This only works in this endpoint, not the deeper nested ones for following etc.

Has these additional fields under the pleroma object:

• tags: Lists an array of tags for the user
• relationship{}: Includes fields as documented for Mastodon API https://docs.joinmastodon.org/api/entities/#relationship
• is_moderator: boolean, nullable, true if user is a moderator
• is_admin: boolean, nullable, true if user is an admin
• confirmation_pending: boolean, true if a new user account is waiting on email confirmation to be activated
• hide_followers: boolean, true when the user has follower hiding enabled
• hide_follows: boolean, true when the user has follow hiding enabled

Source

Has these additional fields under the pleroma object:

• show_role: boolean, nullable, true when the user wants his role (e.g admin, moderator) to be shown
• no_rich_text - boolean, nullable, true when html tags are stripped from all statuses requested from the API

Account Search

Behavior has changed:

• /api/v1/accounts/search: Does not require authentication

Notifications

Has these additional fields under the pleroma object:

• is_seen: true if the notification was read by the user

POST /api/v1/statuses

Additional parameters can be added to the JSON body/Form data:

• preview: boolean, if set to true the post won't be actually posted, but the status entitiy would still be rendered back. This could be useful for previewing rich text/custom emoji, for example.
• content_type: string, contain the MIME type of the status, it is transformed into HTML by the backend. You can get the list of the supported MIME types with the nodeinfo endpoint.

PATCH /api/v1/update_credentials

Additional parameters can be added to the JSON body/Form data:

• no_rich_text - if true, html tags are stripped from all statuses requested from the API
• hide_followers - if true, user's followers will be hidden
• hide_follows - if true, user's follows will be hidden
• hide_favorites - if true, user's favorites timeline will be hidden
• show_role - if true, user's role (e.g admin, moderator) will be exposed to anyone in the API
