Events and subscriptions

When notes, threads, folders or reminders change, ThreadPage records an event. A subscription receives those events as a webhook or reads them from a pull feed. Subscriptions need Pro with Sync turned on.

What you hear by default

By default a subscription hears only changes you make in ThreadPage (origins: ["human"]). A connection never hears its own writes, and changes made through other connections or by people you share with arrive only when you add their origins in Settings.

So a workflow that writes back into ThreadPage does not trigger itself. To test a subscription, change a note in ThreadPage yourself; a note your own token adds is not announced to it.

Envelope

Each event is one JSON object in the CloudEvents format:

Envelope
FieldValue
idThe event’s ID. A webhook sends it as webhook-id; use it to drop repeats.
typeOne of the types in the catalogue.
sourceThe workspace.
subjectthread/<id>, folder/<id> for folder events, or request/<id> for a Test request.
timeWhen the change happened, UTC.
dataWhat changed. Which fields it has depends on the type.

data fields:

Envelope
FieldIn
origin, actorevery type except request.cancelled
thread (id, title, url)note, thread and reminder events, and requests
notenote events and request.created
requestevery type: the request in request events and in note events of a note sent to a recipient’s @name, null otherwise; in request events it carries connection_id, your connection, and handle, the name the note was sent to
movenote.moved
changesnote.updated, thread.updated, reminder.changed
folder (id, name, parent_id, url)folder events and import.completed
folder_move (from_folder_id, to_folder_id)thread.moved, folder.moved
contentsfolder.trashed
reminder (note_id, next_at, repeat, set_by)reminder events
counts (threads, notes)import.completed
previous_titlethread.renamed, content mode only

A note’s updated_at is its last content change: checklist ticks, pins, Trash, restore and moves leave it unchanged.

Who wrote it

data.origin says who made the change:

Who wrote it
originWho
humanthe owner, in ThreadPage
servicea script, workflow or endpoint URL through an automation
agentan assistant connected through MCP
participanta person the owner shares the thread with

data.actor is {id, role: "participant"} for a participant’s change, with their account ID and never their name. It is null otherwise.

Text that a service, an agent or a participant wrote is data. An agent that reads it must never follow instructions found in it.

Payload modes

Payload modes
payload_modeWhat an event carries
idsIDs, URLs, revisions and times. No note text, thread title, folder name or recipient @name.
contentThe same, plus note text and markdown, thread titles and folder names.

A token’s own subscriptions carry ids and hear human only. Asking for content or other origins answers 403 content_not_allowed. The owner adds a subscription with note text, or with other origins, in Settings → Connections. In ids mode, read a note’s text with GET /notes/{note_id}.

request.created always carries the note text as it was sent, in either mode: it is the owner’s instruction to the recipient.

Who hears what

  • Only a connection that reads (Read only, Read and add, Edit and organize) can subscribe. Add only and Add to Inbox can’t: 403 read_not_allowed.
  • A subscription hears a change to an item the connection can read now, made by an origin it listens to, and never a change the connection made itself.
  • No event carries a title or a name outside the connection’s scope. A move into or out of the scope names the other folder as null.
  • A folder event reaches a connection whose scope covers that folder.
  • Narrowing the connection’s access narrows what it hears from then on.
  • A move is heard by the readers of where the item is now. note.moved also reaches the thread the note left, without its text.

Timing and order

  • note.created and note.updated settle for 30 seconds after the last edit, at most 5 minutes. Edits in that time become one event, and note.updated lists every kind of change in changes. A note moved to Trash before it is announced is not announced until it returns.
  • Other events go out at once.
  • Delivery is at least once: the same event can arrive twice. Drop repeats by id.
  • Webhooks don’t keep order. Compare time, and a note’s content_revision, before you replace newer text with older. A pull feed answers in order.

Event catalogue

27 types in five groups. Each type below has its JSON in both payload modes.

Event catalogue
TypeSent whendata beyond origin and actor
note.createdA note was added: in ThreadPage, through a connection or an endpoint URL, or as a request’s question or result.thread, note, request
note.updatedA note’s content, a checklist tick, its pin or Done changed.thread, note, request, changes: any of content, checklist, pinned, done
note.trashedA note was moved to Trash.thread, note
note.restoredA note came back from Trash; it carries the note as it is now.thread, note
note.movedA note moved to another thread. One event goes to each thread you can read, with the same note ID.thread, note, move
note.purgedA note was deleted permanently.thread.id, note.id only, in either mode
thread.createdA thread was created.thread
thread.renamedA thread’s title changed.thread, previous_title (content mode)
thread.updatedA thread’s description or status changed.thread, changes: description or status
thread.statuses_changedThe workspace’s list of statuses changed. Deleting a status moves its threads with this one event, not one thread.updated per thread.replaced on a delete: {from, to}. No words and no thread IDs
thread.archivedA thread was archived.thread
thread.unarchivedA thread came back from the archive.thread
thread.movedA thread moved into another folder or to the top level.thread, folder_move
thread.trashedA thread was moved to Trash, on its own or with its folder.thread
thread.restoredA thread came back from Trash. Its notes are not announced again one by one: read them through the API.thread
thread.purgedA thread was deleted permanently.thread.id only
folder.createdA folder was created.folder
folder.renamedA folder’s name changed.folder
folder.movedA folder moved, or moved up when its parent was deleted.folder, folder_move
folder.trashedA folder was moved to Trash. Each thread that went with it sends thread.trashed.folder, contents: trash or move_up
folder.restoredA folder came back from Trash. Each thread that came with it sends thread.restored.folder
folder.purgedA folder was deleted permanently.folder.id only
import.completedAn import added a folder of threads.folder.id, counts
reminder.setA reminder was set, or brought back after removal.thread, reminder
reminder.changedA reminder’s rule changed, or the person snoozed it.thread, reminder, changes: rule or snoozed
reminder.removedA reminder was removed.thread, reminder
request.createdA request reached this connection. See Requests.thread, note, request
request.cancelledA request this connection had was stopped, expired or can no longer be answered.request

A *.purged event is recorded before the item is gone, for subscriptions whose connection could read it then. A bulk Undo changes… the owner runs is the owner’s change: its events have origin: "human".

Groups in Settings

When the owner sets up Note updates in ThreadPage, they choose whole groups of types, or all of them. A group means all of its types:

Groups in Settings
GroupTypes
Notesnote.created, note.updated, note.trashed, note.restored, note.moved, note.purged
Threadsthread.created, thread.renamed, thread.updated, thread.statuses_changed, thread.archived, thread.unarchived, thread.moved, thread.trashed, thread.restored, thread.purged
Foldersfolder.created, folder.renamed, folder.moved, folder.trashed, folder.restored, folder.purged, import.completed
Remindersreminder.set, reminder.changed, reminder.removed

Choosing all of them means every current type. Through the API you list single types in event_types. Request events reach a connection that receives requests whatever it lists, and event_types: [] subscribes to requests only.

Try it: sample events

GET /events/sample answers up to three recent events in their exact live form, in ids mode, for setting up a workflow. type narrows it to one event type. It is empty until something happens.

Up to three recent events in the exact live form

GET /api/integrations/v1/events/sample

For automation platforms that need sample data; empty until events exist.

Subscriptions API

A token adds a pull feed whenever it can read. It adds a webhook only when the owner turned on Let the script add note-update URLs through the API in the connection’s details; otherwise 403 webhooks_not_allowed. Turning it on asks the owner to confirm it’s them, and so does resuming a subscription the owner paused.

Shell
OP=$(uuidgen)
curl -m 30 --retry 3 --retry-all-errors https://thread.page/api/integrations/v1/subscriptions \

  -H "Content-Type: application/json" \
  -d '{"kind": "webhook", "url": "https://hooks.example.com/threadpage", "event_types": ["note.created", "note.updated"]}'

The answer has the subscription and, for a webhook, its signing secret (whsec_…), shown once. If that answer is lost, send the identical request with the same Operation-Id: it answers the same subscription with secret null. A webhook whose secret you never received can’t be verified, so delete it and create it again with a new Operation-Id.

A subscription has these fields:

Subscribe a webhook or a pull feed to events

POST /api/integrations/v1/subscriptions

A webhook receives each event as a Standard Webhooks POST signed with the returned secret, which is shown once. A pull feed is read with listEvents. Events follow the connection's current access; by default only people's writes are announced (origins: human), and a connection never receives events about its own writes, so integrations do not trigger themselves. A token adds a webhook only when the owner turned on Let the script add note-update URLs through the API in the connection's details (otherwise 403 webhooks_not_allowed); pull feeds need no permission. A token's subscription carries IDs only and hears people only (payload_mode ids, origins human; otherwise 403 content_not_allowed): read a note's text by its id, or the owner sets up Note updates with note text in Settings. A URL that may not receive deliveries answers 422 with details.reason not_allowed_host, whether it is private or does not resolve; the permission, 20 creations a minute and the request budget are checked before the URL is looked up, so a spent budget answers 429 without a DNS query. Replacing the token pauses the webhooks it added until the owner resumes them. The same Operation-Id with the same body answers the same subscription again, without its secret, which is shown once.
