description: TreasurySpring is a digital platform for institutional cash management that helps organisations holding large
  excess cash balances minimise risk, maximise return and optimise time by diversifying across secure counterparties via standardised
  Fixed Term Funds (FTFs). Its Public API (OpenAPI 3.1) gives an authorised user programmatic access to their entities, fund
  cells, obligor exposures, indications, subscriptions, holdings, tasks and a normalised event stream — the full FTF lifecycle
  from subscription to live holding — with OAuth 2.0 auth, offset and cursor pagination, webhooks, and a published, read-only
  Model Context Protocol (MCP) server for AI agents.

  name: TreasurySpring Event Checkpoints API
  description: 'Server-managed cursors for stateless event stream consumers.


    In most cases, checkpoints are not needed. If your system can persist data locally (e.g. in a database, file, or key-value
    store), store the `cursor` value from `GET /event` yourself and pass it as `start_cursor` on the next request.


    **When to use checkpoints:**


    Use this endpoint if your system runs in an environment that cannot reliably persist state between invocations — for example,
    a stateless function, a script with no backing store, or a system that delegates position tracking to TreasurySpring entirely.


    A checkpoint is a named record stored server-side that remembers where your last successful sync run ended. Instead of
    storing the cursor yourself, you store it here and retrieve it at the start of each sync run:


    1. **Create** a checkpoint once: `PUT /event/checkpoint/{name}` — the cursor is initialised to the current end of the
    event stream.

    2. **Read** the checkpoint at the start of each sync run: `GET /event/checkpoint/{name}` → `cursor`, `checkpointVersion`.

    3. **Fetch events** from that cursor: `GET /event?start_cursor={cursor}`.

    4. **Advance** the checkpoint after successful processing: `PATCH /event/checkpoint/{name}` with `expectedCheckpointVersion`
    and `newCursor`. The `checkpointVersion` acts as a safety check — if another process has already advanced the checkpoint
    since you last read it, the request returns a 409 Conflict with the current state so you can reconcile before retrying.


    Checkpoints are scoped to the authenticated API user.'
