Explore or present the complete seller journey in a temporary Storefront without connecting production systems. Demo Storefront uses the same product, readiness, policy, and Brief History surfaces as a live Storefront. Its Seller Dashboard has a separate, explicitly synthetic evaluation view rather than treating rehearsal facts as live seller analytics.
Demo Storefront data is synthetic. A profile may include vendor-shaped inventory or capabilities, but it never connects to or emulates Google Ad Manager, FreeWheel, Epsilon, Cadent, or another vendor API.

Who can create one

This page describes the current Demo Storefront compatibility flow. There is not yet a customer-facing Add sample data action for an ordinary account. Demo creation must not be treated as customer approval for that future account-level action. When that action becomes available, it will require account-administrator approval for the exact synthetic logical-source revision and renewed approval after a material revision change.
An Apostra platform administrator creates a Demo Storefront as a separate seller account from Add account. The administrator names the demo and chooses a Seller capability profile—Listing, Listing + Distribution, Merchandising, or Merchandising + Distribution—plus a Display, CTV, Retail Media, or Mixed Publisher synthetic source pack. New demos default to Merchandising + Distribution. Ordinary customer accounts do not show demo-creation controls. The selected demo organization uses its real account permissions and applicable terms. Apostra cannot accept terms for a presenter, prospect, or another user, and a demo never converts or resets an existing live Storefront. The chosen synthetic source pack and Seller capability profile apply only to that Demo Storefront while its lease is active. The lease captures the exact profile revision and its requirements. It does not create a commercial profile or entitlement assignment. Commercial profiles remain assigned to the billing organization and may apply to its other accounts. Initial creation of a new demo and explicit reset operations also converge one credential-free synthetic managed source for the exact authenticated Demo Storefront. A demo created before this source was available receives it on the next operator-triggered Reset. Retrying create for an existing demo leaves that demo unchanged. The server requires an ACTIVE, unexpired lease and never calls a vendor or uses vendor credentials. Signing in again, returning to the demo, opening a Page, reading its status, or extending its lease does not provision, reactivate, enroll, or create another identity. Deletion or expiration removes only the Demo Storefront and its synthetic data, not your account.

Sample Publisher Display

The initial versioned profile is Sample Publisher Display. It includes:
  • a synthetic modular inventory source;
  • a credential-free synthetic managed source with fixed Inventory component selectors and Signals candidates;
  • two display products and deterministic availability;
  • CPM pricing in USD;
  • audience, context, device, and geography facts;
  • sample approval routing with one pending media buy and one pending creative review;
  • a fictional evaluation brief and its terminal response evidence; and
  • no buyer demand, booking, revenue, attribution, or delivery claim.
The profile and sample-data versions appear with the DEMO status so a presenter can verify exactly which scenario is open.

Review the sample approvals

Open Approvals & operations to review two pending items. The creative is a clearly labelled, fictional 300×250 display example for the sample campaign. Its preview is assembled as static text inside Apostra. It contains no customer data, credentials, trackers, or calls to an external service. The sample creative follows the same review queue, assignment, approval, and rejection workflow as another pending creative. Reset returns both sample approvals to pending without adding duplicate queue items. Expiration and Delete now remove the approval rows, routing, preview, and work items with the rest of the synthetic Storefront. Platform administrators can add CTV and Retail Media sources at creation. The Mixed Publisher pack combines Display, CTV, and Retail Media; it is not a fake vendor adapter.

Synthetic source readiness

Seller Setup reports each code-owned Demo recipe as 9 of 9 ready while the authenticated Storefront’s Demo lease is active and unexpired. Source Diagnostics labels the same source Local synthetic and explains that its persisted recipe replaces live endpoint verification. There are no vendor credentials, capability refreshes, protocol traces, or external source tests to run. If the lease is missing or expired, belongs to another tenant, or the source is not a demo-* recipe, Apostra uses the ordinary live-source checks. Reading readiness does not create or extend a lease or change the selected Seller capability profile.

Guided seller preview

A guided seller preview may use a media kit, rate card, or facts supplied in the conversation to draft additional synthetic placements in the existing Demo Storefront source. The guide shows the exact draft rows before the seller confirms the write. A representative brief can then demonstrate a response from those confirmed inputs, including the response artifact and its recorded reasoning. Before asking for an upload, the guide presents the Terms of Service that govern seller-provided material in this preview. Read the agreement’s Data Use and Confidentiality sections for the controlling terms. This product page does not paraphrase or extend those terms with a separate storage-duration or automatic-deletion promise. The reset, expiration, and deletion controls below describe the Demo Storefront and its synthetic resources, not a different contract for the original uploaded document. Seller-provided names, prices, capacity, dates, audience statements, and other facts are not independently verified by this flow. The guide attributes them to the seller, does not silently fill missing commercial values, and does not present the resulting placements as live-synced inventory. The Demo disclosure continues to apply to products and proposals returned from the source. The guided preview does not connect a production inventory system or prove a live booking, transaction, trafficking action, or delivery. If the seller asks about a production source or later lifecycle stages, use the documented source and media-buy workflows rather than projecting the preview result forward. The preview also does not define pricing, billing, data handling, or conversion terms; those come from the applicable agreement and public documentation.

Expiration and controls

New Demo Storefronts expire after seven days. The Demo Storefront card shows the expiration time and supports:
  • Reset — rebuild the selected synthetic inventory and preserve the selected Seller capability profile. Reset does not change the expiration time.
  • Extend 7 days — add seven days to the current expiration time.
  • Delete now — immediately remove the Demo Storefront and its synthetic resources while preserving the account.
Automatic cleanup uses the Demo Storefront’s durable expiration record. If cleanup fails, the status remains visible and the platform retries; it does not silently leave an expired Storefront active.

Evaluation analytics in Seller Dashboard

While the Demo Storefront lease is active, its signed-in seller can open Seller Dashboard to inspect a Synthetic evaluation data view. It reports the current lease generation’s terminal evaluation RFP facts through the same RFP performance calculation used by Seller Dashboard, along with each RFP and turn ID, response state, profile disclosure, and lease expiration. The view is rehearsal evidence only. It does not report or imply buyer demand, commercial outcomes, bookings, revenue, attribution, learned posture, or delivery. Standard Seller Dashboard analytics remain live-only. An evaluation run is not relabeled as live data. The projection is available only to the authenticated owner of the exact active Demo Storefront lease. It excludes another Storefront, another tenant, live and draft RFPs, a previous lease generation, and rows before the last reset. If the lease expires, resets, is missing, or cannot be resolved unambiguously, the evaluation view is not returned. An empty view means that no terminal evaluation runs exist for the current lease generation; it does not say anything about buyer demand.

Open the management Page from an agent

The portable demo management Page works through the shared MCP app contract. An agent on the v3 Seller surface can open an existing demo with open_page({ page: "demo_seller" }). The Page lets an authorized seller inspect the lease and recipes, attach or remove optional synthetic sources, reset the profile, extend the lease, or delete the demo. A provisioned standalone Demo Storefront seller can open the existing Demo Storefront card in the setup rail without a modular inventory source entitlement. This changes seller-side access to the existing management Page only. It does not change what buyers can discover, call, or see from a Demo Storefront. Opening the Page does not grant new permissions and does not create a Demo Storefront. Creation remains an Apostra platform-administrator action in Add account, and legal terms remain accepted by the authorized human for the selected organization.

What a buyer’s agent sees

A Demo Storefront is a real, callable AdCP seller — a buyer’s agent can send it get_products and reach it through ordinary discovery like any other Storefront. Because its inventory is synthetic, every response is marked so an agent never mistakes it for a real seller: Both fields are additive inside the namespaced ext object returned alongside the normal products and proposals in the same get_products response. An agent that does not recognize Scope3 namespace can safely ignore it; one that does should treat any proposal or product from a response where ext.scope3.storefront.demo is true as a demonstration, not a real offer. The same disclosure sentence also appears in the response’s human-readable summary text. Because there is no real seller-side transaction to prove for synthetic inventory, the Storefront’s publish_validation readiness requirement reports complete with method: "demo_mode" instead of pending — a Demo Storefront never gets stuck waiting on a no-spend test campaign it has no real path to run. That exemption only applies while every connected source is part of the demo profile; if a real source is ever attached, the normal requirement resumes for the whole Storefront.

What is real

Account permissions, the Storefront, products, availability, policy, brief history, and expiration use normal platform behavior. Inventory facts, the fictional buyer, campaign, evaluation evidence, delivery examples, and upstream references are synthetic. The special evaluation view is disclosed as synthetic; ordinary seller analytics remain live-only. Wonderstruck is a separate real-integration sandbox and does not back Demo Storefront. Isolated engineering test environments also remain separate.
