# Replace an uploaded page bundle

> Requires page.update. Replaces files only for HTML pages whose source is upload. Accepts HTML or ZIP with server-configured size limits. Returns the existing page publication timestamp; this operation does not clear it.

info:
  title: Trackup API
  description: >-
    API-key-accessible Trackup operations. Send your key in the `X-Api-Key`
    header.


    Keys belong to a team. `X-Team-Id` is not required; if supplied, it must
    match that team.


    Each operation lists its required key permission. The key creator must
    remain a team member and normally hold that permission. The ingest-only
    permissions `visitor.create`, `conversion.create`, and `request.create` do
    not need to be held by the creator.


    Project access and selection are described per operation. Session-only
    account, administration and OAuth operations are not part of this reference.


    The same operations are available as MCP tools at `/mcp` (Streamable HTTP).
    Authenticate with `X-Api-Key` or connect through OAuth, which issues an API
    key on consent.


    Schema validation errors return HTTP 422 with an `errors` object. Other
    errors generally contain `error` and `message`; operation-specific responses
    describe exceptions.
