}Update a page
Replaces a page’s HTML and/or renames it as a new revision under the same id: its link, share link and Library row stay, so one page stays one page. Works on any page you may see, from any Session, as the agent’s app_show with page_id does; send the whole new page (getPage with include=source gives back the current one). Checked as createPage checks a page. Requires pages:write and a member who may write.

}Authorizations
Your Reason API key from Settings › API keys. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, devices:read, devices:write, devices:use, computers:read, computers:write, ssh:write, knowledge:read, memory:read, memory:write, skills:read, skills:write, pages:read, pages:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, network:read, network:write, automations:read, automations:write, agent_auth:read. devices:write, devices:use, computers:read, computers:write, ssh:write, network:read and network:write are opt-in, excluded from default keys. computers:read lists visible cloud and connected computers without waking them or granting execution access. devices:read discovers local Device targets; devices:use separately consents to local execution, so a discover-and-run local workflow needs both. devices:write manages enrollment and device grants; computers:write creates or deletes cloud computers; ssh:write manages retained SSH access. network:read reads the saved workspace network policy; network:write replaces custom allowed hosts and requires a current organization owner/admin. Legacy project PATCH requests containing network_allowed_hosts also require network:write plus their existing run scope and project management permission; saved project hosts do not affect current session egress. Only owners/admins can mint or manage keys with network:write; keys cannot grant themselves more authority. See /docs/network-policies for replacement semantics and runtime applicability. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:read reads sessions, including the assistant, reasoning and tool activity in their events. sessions:debug is privileged: only for organization owners/admins, it expands session events to the full diagnostic projection (diagnostic event kinds, status text and raw event metadata).
Path Parameters
Organization id or slug. Resolve it with GET /v3/self.
The page id, returned as id by listPages and createPage, or the page= parameter of a page link.
Body
Response
The page at its new revision (the same revision when nothing changed).
The page's id, from listPages, createPage or a page link's page= parameter.
The page's name.
1 when made, one more for each update under the same id.
page for an HTML page; document for a Markdown document page, which this API reads but does not write.
page, document The Session the page lives in.
The page's link in Reason: its Session opened on the page, for anyone who may read that Session. It never changes.
A short-lived URL that serves the page itself for the caller (sandboxed HTML); null for a document.
When view_url stops loading.
The hero picture of the current revision; null until one is captured (the Library then renders the page live).
Show child attributes
Show child attributes
On create and update: scheduled when the page's Session has a running turn of yours whose machine takes the hero picture now; not_running when it has none, so the Library renders the page live until a later turn shows it.

With include=source: the page's HTML as written (local images inlined), or a document's Markdown.
