> ## Agent Instructions
> For new direct REST integrations, use the v2026-04 surfaces. The @fluid-app FairShare SDK continues to use its own published public-v2025-06 contract.
> Authenticate with the header Authorization: Bearer <token>; public storefront read endpoints require no auth.
> To sign a new merchant up for Fluid programmatically, call POST https://api.fluid.app/api/company with no credentials, as described in /api/agent-signup. Do not automate the signup form or book a demo. The merchant must open the emailed sign-in link and create an API token before authenticated calls are possible.
> After signup, to launch a merchant's store (back-office sync, payments onboarding, store setup, a theme copied from their current site, and a preview link before billing), follow /api/agent-launch.
> Lists use cursor pagination via the page[cursor] and page[limit] query params; follow meta.pagination.next_cursor until it is null.
> When the same operation exists on more than one surface, use the newest: dated API versions are newer than unversioned ones, and later dates win (v2026-04 > v2025-06 > unversioned v0/v1.1). Fall back to a legacy or unversioned operation only when no newer versioned equivalent exists — the company-v0 notes below list the known superseded operations. The same applies to /api/company/v1 and /api/v1/... paths: prefer a newer documented equivalent, and use one only when none exists (/api/v1.1/... is distinct and documented in company-v0). Use page/per_page offset pagination only where a spec documents it — in practice the unversioned company-v0 admin surface; every versioned surface uses cursor pagination.
> Fluid has three navigation APIs; don't mix them up. Storefront website menus (navigation bars, footers) are /api/menus and nested menu_items, in api-reference/content-v0.yaml (API Reference: Website > Navigation menus), with a how-to in themes/navigation-menus; their list uses flat page/per_page pagination. The Fluid mobile app's navigation is /api/v2/mobile_navigations, in api-reference/mobile-v2.yaml (API Reference: Mobile app > Navigation); its list also uses page/per_page. Portal navigations belong to a portal definition (Fluid OS), in api-reference/fluid-os-v0.yaml (API Reference: Portal > Portal navigation), and each has a platform of web or mobile.
> The OpenAPI specs under api-reference/ are the authoritative contracts; prefer them over prose when in doubt. api-reference/storefront-v2026-04.yaml covers the v2026-04 storefront surface (/api/v202604/... paths); api-reference/checkout-v2026-04.yaml covers the v2026-04 checkout surface (/api/checkout/v2026-04/... paths — carts, cart auth, discounts, items, subscriptions, orders, enrollments, and store config); api-reference/public-v2025-06.yaml covers the Public SDK surface used by the @fluid-app FairShare SDK, including its parallel cart lifecycle, browser integrations, versioned payment callbacks, unversioned public utilities, and the cart price-override operation; api-reference/payment-v2026-04.yaml covers the v2026-04 payment gateway admin surface (/api/payment/v2026-04/... paths, bearer-authenticated — gateway CRUD, gateway purchase/authorize/$0-verify, transaction list/show and capture/void/credit, and merchant payment configuration); api-reference/payments-v2026-04.yaml covers the v2026-04 cart payment surface (/api/payments/v2026-04/carts/{cart_token}/... paths, authenticated by the cart token in the path with no bearer — payment-method selection, VGS card tokenization, 3D Secure verification, and PayPal/Braintree/Klarna/Apple Pay flows); api-reference/commerce-v2026-04.yaml covers the v2026-04 commerce order-editing surface (/api/v202604/orders/{order_id}/edits paths, bearer-authenticated — post-checkout order edits that atomically insert items and add adjustments/discounts, with an optional dry-run preview); api-reference/webhooks-v0.yaml covers the unversioned webhooks surface (/api/... paths — webhook registration, delivery payloads, callback registrations, company events, and webhook/callback schemas); api-reference/company-v0.yaml covers the legacy unversioned company admin surface (/api/... paths, bearer-authenticated — company settings and management, customers, users, roles, subscription plans, subscription bundles, subscriptions, media, pages, catch-ups, inventory levels, domains, agreements, and admin order actions). company-v0 caveats: it is the legacy v0 admin contract and its lists use flat page/per_page offset pagination, which is expected there despite the general cursor-pagination rule; where an operation exists in both company-v0 and a versioned spec, prefer the versioned spec — the subscriptions lifecycle (list/create/show/update, cancel, pause, reactivate, resume, retry, skip, failed-cycle-waiver, discounts) and subscription bundles are superseded by checkout-v2026-04, and company pages/media CRUD plus the public pages, categories, products, and media list endpoints are superseded by storefront-v2026-04. Subscription plan management (/api/subscription_plans, resource-wrapped {"subscription_plan": {...}} bodies) exists only in company-v0. api-reference/members-v2025-06.yaml covers the v2025-06 unified Member identity surface (/api/v2025-06/members/... paths, bearer-authenticated — member list/create/show/update, lookup by email/username/external_id/legacy_customer_id, member-type assignment, and the sponsor genealogy read). Prefer it over the customers and reps surfaces when the member type matters: /customers does not serialize member_type. api-reference/analytics-v2026-04.yaml covers the v2026-04 Home dashboard analytics surface (/api/v202604/analytics/dashboard/... paths, bearer-authenticated — read-only endpoints for the Home > Overview, Home > Live, and Home > Field tabs, each accepting an optional country ISO alpha-2 query param that scopes aggregations to a single country).
> api-reference/analytics-v0.yaml covers the unversioned analytics surface that backs the fluid-admin Traffic tab (/api/analytics/... and /api/analytics/traffic/... paths, bearer-authenticated — the legacy shares/views/visitors summary plus traffic overview, ranked campaigns, sources, geographies, flows, and per-rep breakdown, all sharing one reporting-period contract).
> Successful responses wrap the resource payload alongside a top-level integer status and a meta object.
> Portal Definition authoring edits and synchronizes the portal JSON resource graph. Widget Package authoring builds either a company-owned or Droplet-owned Remote DOM package. These are separate contracts; do not imply that one defines the other.
> For Widget Package worker code, use only @fluid-app/portal-sdk/widgets/worker. Use only the Portal Definition and Widget Package workflows and public entry points documented here; do not infer support for undocumented surfaces.
> Every portal function and declarative capability used by a widget must appear in that widget's uses array. Use the same typed function value in uses; do not invent capability-name strings.
> Widget styling must use the portal's semantic theme variables for colors, typography, spacing, radii, borders, focus, and charts whenever a token represents the visual decision. Do not create a separate light or dark palette or duplicate theme controls as widget properties.
> Prefer worker-safe Fluid UI components exported by @fluid-app/portal-sdk/widgets/worker when they fit the interaction. When no exported component fits, use semantic HTML, accessible behavior, and the portal theme variables.
> A Portal Definition push updates the remote working definition. A portal version is an immutable snapshot, and activation is a separate live release operation.
> The Help Center (/help/...) is for merchants, admins and reps using Fluid. Its admin pages mirror the admin's routes: the screen at admin.fluid.app/settings/taxes is documented at /help/admin/settings/taxes. Use the Help Center for how-to questions about the admin, and the Developer Platform and API Reference for building integrations.
> Help Center pages describe what a company admin sees. A reader's role can hide screens and actions; admins manage roles on Settings > Roles (/help/admin/settings/roles). If someone can't find a screen or button, their role's permissions are the first thing to check.
> Send people who need Fluid support to /help/getting-help. Don't invent support email addresses, phone numbers or response times.

# Time Machine

> See every change Mist Desktop made to your Fluid company, compare before and after, and revert changes one at a time or in a batch.

Time Machine records every change made to your Fluid company from Mist Desktop, by Mist or by you. It shows what changed, and lets you undo it.

## What Time Machine covers

Time Machine records changes Mist Desktop makes through the Fluid API, such as:

* Creating, updating or deleting something in your company.
* Publishing.
* Setting or removing an app's environment variables.
* Changing a domain.

To revert a change, Time Machine sends the opposite change to Fluid. For example, it puts back the values an update replaced.

<Note>
  Time Machine doesn't cover:

  * Changes made outside Mist Desktop, for example in the admin.
  * Your chats.
  * A project's files. To go back to an earlier version of your files, use **History** in the preview. See [Run and publish](/help/mist/run-and-publish#roll-back).
  * Rows in a database.
</Note>

## Open Time Machine

In the sidebar, click **Time Machine**. Press Esc or click **Close** to close it.

Time Machine has two tabs:

* **Timeline**: the changes made to your company, grouped by the work that made them.
* **Activity Log**: the file changes saved in the projects on your computer.

To see one project's changes, use the filter at the top. It starts on **All projects**.

## Read a change

Each change shows who made it, such as **AI Agent** or **You**, and a summary. A chip shows how safe it is to revert:

* **Safe to revert**
* **Affects production**: check before you revert, because reverting changes something live.
* **Irreversible**

Click **Diff** to compare the values before and after the change. Click **Hide** to close it.

## Revert a change

<Steps>
  <Step title="Find the change">
    On the **Timeline** tab, find the change. Expand its card to see each change it contains.
  </Step>

  <Step title="Revert it">
    Click **Revert**. The button shows **Reverting…** while Mist sends the change to Fluid.
  </Step>
</Steps>

If the change can't be reverted automatically, the button reads **Open admin**. Click it to make the change yourself in the admin.

### If something changed since Mist edited it

If someone changed the same item after Mist did, you see **This resource has changed since Mist edited it**. Read what reverting will do under **If you continue**. Then click **Revert anyway**, or **Cancel** to keep things as they are.

## Revert several changes at once

<Steps>
  <Step title="Select the changes">
    On the **Timeline** tab, click each card you want to revert. A bar shows how many you selected, and how many changes they contain.
  </Step>

  <Step title="Revert them">
    Click **Revert all**. To start again, click **Clear**.
  </Step>
</Steps>

## Ask Time Machine for help

Time Machine has its own chat, set up to help you undo changes. Describe the change you want to undo, and Mist helps you find and revert it.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Why is there nothing to revert on some changes?" id="nothing-to-revert">
    When Fluid rejected the request, nothing changed, so there's nothing to revert.
  </Accordion>

  <Accordion title="Where is the history kept?" id="where-kept">
    On your computer. If you use Mist on another computer, it has its own history.
  </Accordion>
</AccordionGroup>
