## Cancel a payment request

`payment_requests.cancel(strpayment_request_id)  -> PaymentRequest`

**post** `/v3/payment_requests/{paymentRequestId}/cancel`

Cancels an unpaid payment request: the underlying payment intent is
canceled and the request moves to `canceled`. A request that is already
paid, canceled, or expired returns 409.

### Parameters

- `payment_request_id: str`

### Returns

- `class PaymentRequest: …`

  - `id: str`

    Unique identifier of the payment request.

  - `amount: int`

    Amount in the currency's minor units. In `subscription` mode this is
    the recurring amount (price × quantity) the recipient pays per
    interval, starting at checkout.

  - `checkout_url: str`

    URL the recipient opens to pay:
    `https://zero.linqapp.com/pay/{slug}?session=...`, where `{slug}`
    is your partner checkout slug.

  - `created_at: datetime`

  - `currency: str`

  - `mode: Literal["payment", "subscription"]`

    Whether this request collects a one-time charge or starts a subscription.

    - `"payment"`

    - `"subscription"`

  - `object: str`

  - `status: Literal["requested", "succeeded", "canceled", "expired"]`

    Lifecycle status of the payment request.

    - `"requested"`

    - `"succeeded"`

    - `"canceled"`

    - `"expired"`

  - `description: Optional[str]`

  - `expires_at: Optional[datetime]`

    When an unpaid request auto-expires.

  - `interval: Optional[Literal["day", "week", "month", "year"]]`

    Subscription mode — how often the subscription renews.

    - `"day"`

    - `"week"`

    - `"month"`

    - `"year"`

  - `interval_count: Optional[int]`

    Subscription mode — intervals per renewal (e.g. `3` + `month` = quarterly).

  - `metadata: Optional[Dict[str, str]]`

  - `natural: Optional[Natural]`

    Natural-rail join keys, present when `rail: natural`.

    - `payment_request_id: Optional[str]`

      The Natural payment request (`prq_...`).

    - `transaction_id: Optional[str]`

      The settled transaction (`txn_...`).

  - `paid_at: Optional[datetime]`

    When the request was paid. Absent until it succeeds.

  - `price_id: Optional[str]`

    Subscription mode — the recurring price this request subscribes to.

  - `quantity: Optional[int]`

    Subscription mode — units of the price subscribed to.

  - `rail: Optional[Literal["stripe", "natural"]]`

    The rail this request settled on.

    - `"stripe"`

    - `"natural"`

  - `stripe: Optional[Stripe]`

    Ids of the Stripe objects created **on your connected account** —
    your join keys into your own Stripe Dashboard, webhooks, and API.
    After a subscription's first payment succeeds, its ongoing lifecycle
    (renewals, plan changes, cancellation) is managed in your Stripe
    account using `subscription_id`.

    - `customer_id: Optional[str]`

      The Customer this request is attached to (`cus_...`). Always set
      in subscription mode (created for you unless you passed
      `customer_id`); set in payment mode only when you passed one.

    - `payment_intent_id: Optional[str]`

      The PaymentIntent collected at checkout (`pi_...`).

    - `subscription_id: Optional[str]`

      Subscription mode — the Subscription (`sub_...`).

  - `trial_end: Optional[datetime]`

    Subscription mode — when the free trial ends and the first charge
    happens. Present only on trial requests; `paid_at`/`succeeded` mean
    the payment method was collected (no funds move until this time).

  - `updated_at: Optional[datetime]`
