An agent can complete checkout while the purchase still needs attention. The merchant must accept the order, the item must arrive, and any cancellation or refund must produce evidence outside the chat. A useful shopping agent should keep those states distinct and tell the buyer which party can take the next action.
Meta Muse’s Link integration provides a concrete example. Stripe’s September 8 announcement describes payment using a saved Link method at participating businesses or a single-use virtual card scoped to the approved purchase elsewhere. The user approves the transaction total in chat. That approval does not establish delivery, return acceptance or protection eligibility.
- 01Payment is one state in the purchase.Preserve the merchant order reference as well as the payment result.
- 02A request is not a completed remedy.Cancellation, return and refund each need their own acknowledgement.
- 03Muse has specific coverage terms.Use the guide assigned to the purchase, not a generic headline benefit.
- 04The buyer still needs evidence.An agent can assist, but missing receipts or deadlines cannot be replaced by a confident summary.
01 — Practical decisionWho acts at each purchase state #
The matrix is an operational map for evaluating a shopping workflow. It identifies the actor to check and evidence worth preserving; it is not a universal allocation of legal liability. The merchant of record must be identified from the actual sale. These sources do not establish that Muse becomes the seller.

|---|---|---|---|
| State | User / agent | Merchant / payment or claims provider | Evidence to retain |
| --- | --- | --- | --- |
| Approval | User: approve the total. Agent: submit only the agreed purchase. | Merchant: present the order. Payment provider: enable the approved payment. | Approved total, item, seller, address and time. |
| Merchant acceptance | User: check the result. Agent: preserve the merchant response. | Merchant: confirm or reject the order. Provider: report payment status. | Order reference plus payment status; neither replaces the other. |
| Delivery | User: inspect receipt and condition. Agent: track if authorized. | Merchant/carrier: provide delivery evidence. Provider: no delivery conclusion from payment alone. | Tracking, delivery record and item-condition evidence. |
| Cancellation | User: request cancellation. Agent: send it if authorized. | Merchant: confirm whether cancellation took effect. Provider: reflect any payment change. | Request time and merchant acknowledgement. |
| Return request | User: state the reason. Agent: assist with the request. | Merchant: apply the return process. Provider: separate protection review where eligible. | Policy, correspondence, return authorization and shipping evidence. |
| Refund | User: verify the credit. Agent: report what was confirmed. | Merchant: confirm refund initiation. Payment provider: expose the credit’s status. | Refund reference, amount, destination and posted credit. |
| Protection claim | User: provide accurate evidence. Agent: organize it if authorized. | Cover Genius: administer the claim. Stripe: does not adjudicate it under the terms. | Applicable coverage guide, claim reference and supporting documents. |

02 — Practical decisionKeep the approved purchase and the accepted order together #
Approval should be inspectable after the task ends. Save what the buyer authorized, including the item variant, merchant, total and delivery destination. If the agent later discovers a different price or substitute item, that is a changed purchase to resolve with the buyer, not merely a checkout detail.
Stripe says Muse does not see the underlying payment details and that the virtual card is scoped to the approved purchase. Those controls address payment access. They do not tell the buyer whether the chosen size is correct or whether the merchant has accepted the order.
A robust completion message should distinguish an approved transaction, a submitted checkout and a confirmed order. When a page times out after payment, inspect the merchant and payment records before trying again. An agent that automatically retries an uncertain checkout can create a second order even when its first result looked incomplete.
Our agent-checkout authentication guide covers the permission side. The post-purchase requirement is to preserve the link between that permission and the actual external result.
03 — Practical decisionSeparate cancellation, return and refund #
A cancellation request can arrive after an order is already being fulfilled. A return request can be accepted before the item has been shipped back. A refund can be initiated before the buyer sees a credit. These are useful distinct statuses for a workflow; do not compress them into one resolved label.
For cancellation, keep the merchant’s answer and any conditions. For a return, keep the reason, authorization and shipping evidence. For a refund, keep the amount, reference and destination, then verify what the payment account actually shows. If any stage remains pending, say which party must respond next. This is also where agent permissions should become narrower. Permission to purchase an item does not automatically define the buyer’s preference between a replacement, store credit and cash refund. Ask for the choice when the remedy differs materially from the original instruction.
A merchant evaluating agent orders should ensure the buyer can reach the order record and support channel independently of the agent conversation. That is a practical design recommendation, not a claim that every merchant already exposes such a path. Our agent-checkout trust analysis examines why confidence in checkout does not settle the rest of the experience.
04 — Practical decisionUse the Muse-specific protection guide #
The Link support overview lists general benefits, but the terms effective September 8 assign eligible US purchases made using Muse to section 6.2’s separate Guide to Benefits. Paying through Link alone does not guarantee eligibility. Cover Genius administers claims; Stripe does not adjudicate them under these terms.
The following is a compact summary of the Muse guide linked from section 6.2. Caps are conditional maxima, not promised payments. No-fee returns concerns return shipping and restocking charges. Read the actual guide for the applicable benefit before relying on it.
| Link terms, section 6.2 and its Muse Guide to Benefits ; read September 9, 2026. Amount paid and other conditions can reduce recovery. | ||
|---|---|---|
| Benefit | Limit | Coverage / submission timing |
| --- | --- | --- |
| Damage / theft | $500 per item; $50,000 per 12 months | 90 days from purchase; report within 60 days of loss or as soon as reasonably possible; documents within 180 days of incident. |
| Price protection | $500 per item; 4 items/year | Lower price within 90 days of purchase or delivery, whichever first; submit within 90 days of purchase. |
| No-fee returns | $250 return fees/item; 4/year/account | Return within 90 days of purchase or delivery, whichever first; documents within 30 days of return. |
| Refund guarantee | $1,000 per item; 4 items/year | Merchant refuses return within 60 days of purchase or delivery, whichever first; guide says documents within 30 days of return. |

The guide excludes professional/commercial-use purchases, among other categories; refund and return benefits exclude damaged or defective items. Refund coverage excludes shipping and taxes. This is not the full exclusion list. Its refund submission wording refers to a return date even after merchant refusal: obtain clarification from the administrator rather than infer an extension.
For a business owner, the commercial-use exclusion is a reason to assess the actual purchase purpose before treating consumer protection as a procurement backstop. Do not build an approval flow that assumes the maximum benefit will absorb a mistaken purchase. Keep the coverage version with the purchase record. A generic help article and a guide assigned by transaction date can describe different scopes. The reader’s question is which terms apply to this order, not which headline limit is largest.
05 — Practical decisionDesign the handoff for a person who must resolve a problem #
The most useful handoff is a compact purchase record: what was approved, which merchant accepted it, what remains pending and where the supporting evidence lives. Include the order and payment references without exposing unnecessary card or account data. The buyer should not have to reconstruct the transaction from a long chat.
Test an ordinary failure as well as a successful checkout. For example, evaluate how the workflow reports an unavailable item or a merchant that has not answered a cancellation request. The acceptance criterion is whether the user knows the next action and can take it, not whether the agent maintains a reassuring tone.
Measure post-purchase work separately from checkout time. If a shopper saves time buying but spends longer finding receipts and resolving returns, the overall workflow may not improve. Use the payment-token guide for the payment architecture and the retailer-redirect analysis for another model of merchant handoff.
The same design principle applies to a merchant: make the accepted order, return instructions and refund confirmation understandable to a person. An agent may read those records, but the customer still needs a reliable way to inspect and contest what happened.

06 — Next stepWhat to do next #
Treat the purchase as complete only when the relevant state is confirmed.
Keep approval, order acceptance, delivery and remedies distinct. Preserve evidence at each transition and route an unresolved step to the actor who can resolve it. Check the purchase-specific protection terms before presenting reimbursement as an available remedy.
