Subscription cancellation by agent

Cancelling a subscription is one of the errands people most want to hand to an agent, and one of the few where the business on the other side does not want it to be fast. This page covers what a direct agent-to-agent cancellation would need, and where the law stood when we checked on 2026-09-26.

How it works today

Sign-up takes a click. Cancellation usually runs through account settings, a chat, or a phone line, often with a retention step: a discount, a pause option, or a survey before the final button. Agents acting for people today work through those same flows with browser automation or phone calls.

This is a use case where businesses resist. A cancellation is lost revenue, and retention flows are designed to recover some of it. A business has little incentive to publish an agent endpoint that cancels in one request. Where easy cancellation exists, it is mostly because the law requires it.

United States, federal. The Restore Online Shoppers’ Confidence Act (15 U.S.C. 8403) requires sellers using an online negative option feature to disclose material terms, get express informed consent before charging, and provide simple mechanisms to stop recurring charges. The FTC’s 2024 amendments to its Negative Option Rule (16 CFR Part 425) went further, requiring cancellation at least as easy as sign-up. The 8th Circuit vacated those amendments in full on 8 July 2025 in Custom Communications, Inc. v. FTC, holding that the FTC skipped a required preliminary regulatory analysis. On 12 February 2026 the FTC recodified the rule’s pre-2024 text, which covers only prenotification plans. On 13 March 2026 it published an advance notice of proposed rulemaking asking whether and how to amend the rule again; comments closed on 13 April 2026. As of 2026-09-26 no new rule has been proposed or issued.

California. The Automatic Renewal Law (Business and Professions Code section 17602), as amended by AB 2863 for contracts entered, amended or extended on or after 1 July 2025, requires that a consumer who signed up online can cancel online, at will, through a direct link or button or a termination email. Cancellation must be available in the same medium the consumer used. A business may present a retention offer during cancellation only while telling the consumer they can still cancel or showing the cancel option at the same time. Annual subscriptions need an annual reminder, and price changes need advance notice.

Canada. Cancellation rules are provincial. In Ontario, the Consumer Protection Act, 2002 still applies: the government’s guidance says a business must give written notice of changes, renewals or extensions and offer the option not to accept them. The Consumer Protection Act, 2023 is marked “not yet in force” on e-Laws (checked 2026-09-26). In Quebec, Bill 10 (2026, c. 16) received assent on 12 June 2026, and its coming-into-force section puts most provisions in force on 12 September 2026. It adds two rules to the Consumer Protection Act. Section 187.28 requires a merchant that concludes an online contract involving sequential performance, which the consumer may cancel without cause, to offer cancellation through a readily identifiable online button. Section 187.29 requires written notice, within a time set by regulation, before a free or reduced-price period ends, stating the end date and the price that will apply.

The agent-to-agent version

Illustrative. The person has told their agent to cancel a streaming plan at the end of the current billing period and to decline any retention offer.

1. The agent sends a cancellation request with the subscription ID, the effective date (end_of_term) and a flag declining offers.
2. The provider’s agent moves the task to TASK_STATE_AUTH_REQUIRED and asks for proof the account holder approved the cancellation.
3. The agent presents a credential scoped to “cancel subscription SUB-3310”, obtained from the person out of band.
4. The provider’s agent completes the task and returns a confirmation artifact: confirmation number, effective date, and whether any further charge will post.

The request in step 1:

{
  "jsonrpc": "2.0",
  "id": "req-cxl-1",
  "method": "SendMessage",
  "params": {
    "message": {
      "messageId": "msg-cxl-01",
      "role": "ROLE_USER",
      "parts": [
        { "text": "Cancel this subscription at the end of the current term. The account holder declines retention offers." },
        {
          "data": {
            "subscriptionId": "SUB-3310",
            "effective": "end_of_term",
            "retentionOffers": "decline"
          },
          "mediaType": "application/json"
        }
      ]
    }
  }
}

What has to be true

Identity. The provider needs to know which agent is calling and which account holder it represents. The account holder’s login credentials are the wrong tool: handing them to an agent makes the agent indistinguishable from the person.

Authority. The credential should allow exactly one action on one subscription, expire soon, and be revocable. A2A gives the signal (TASK_STATE_AUTH_REQUIRED) and, in section 7.6 of the specification, leaves the credential’s scope, format, validity and revocation to implementations or extensions. A credential that permits “cancel SUB-3310” must not permit a plan change or a new payment method.

Record. The confirmation number, effective date and final-charge statement are what the person needs if charges continue. That record is also the evidence for a card dispute if the business keeps billing. See billing disputes.

Retention offers. California’s rule on retention offers is written for a person looking at a screen. How an offer should be presented to an agent, and whether a pre-declared “decline offers” instruction satisfies anyone’s rule, is not addressed in the texts we reviewed.

Where Emissar fits

• Mandate (spec in progress): a scoped, revocable credential stating that the account holder authorized this cancellation and nothing else.
• Ledger (spec in progress): a signed receipt of the cancellation and its effective date, retrievable by both sides.
• Verify (in development): lets the provider check the calling agent before acting.
• Front Door (open to design partners): only relevant if the subscription business chooses to accept agent requests. For the reasons above, few will volunteer.

Open questions

• Would a cancellation sent by a verified agent count as the consumer using the “simple mechanism” ROSCA requires, or the online button Quebec’s section 187.28 requires? The texts are written for people, and we found no guidance addressing agents.
• If the FTC proposes a new negative option rule after its March 2026 notice, will it say anything about agents acting for consumers?
• Should a provider be able to require a live confirmation from the person, and if so, how does that differ from a retention obstacle?
• Can a consumer’s agent rely on Quebec’s button and California’s online path through browser automation when no agent endpoint exists, and how will businesses treat that traffic?
