  "how": {
    "incantation": "When an update should cancel a subscription at the current period end after payment succeeds, update it with `payment_behavior=pending_if_incomplete` and `cancel_at_period_end=true`. Stripe stores the setting in `pending_update` if payment fails or requires customer action; a conflicting later cancellation value expires the pending update.",
    "examples": [
      "curl https://api.stripe.com/v1/subscriptions/<subscription_id> \\\n  -u \"<YOUR_SECRET_KEY>:\" \\\n  -d payment_behavior=pending_if_incomplete \\\n  -d proration_behavior=always_invoice \\\n  -d \"items[0][id]=<subscription_item_id>\" \\\n  -d \"items[0][price]=<price_id>\" \\\n  -d cancel_at_period_end=true"

    "gotchas": [
      "subscription_id (required): Subscription ID in the update URL.",
      "payment_behavior (required): Set to `pending_if_incomplete` to use pending updates.",
      "cancel_at_period_end (required): Set to `true` to cancel at the current period end; supported for pending updates.",
      "proration_behavior: `always_invoice` creates an invoice and attempts payment when the update is made.",
      "items[0][id]: Subscription item ID to update; included in the documented example.",
      "items[0][price]: Price ID to apply to the subscription item; included in the documented example.",
      "Prerequisite: Pending updates require `collection_method=charge_automatically` and a supported payment method.",
      "Prerequisite: The update must generate an invoice to trigger a pending update; `proration_behavior=always_invoice` does so in the documented example.",
      "Prerequisite: Authenticate the API request with a Stripe secret key.",
      "cancel_at_period_end is a nullable boolean property of pending_update on a Subscription.",
      "The cancellation takes effect at the end of the current billing period after the pending update applies.",
      "A conflicting cancel_at_period_end value in a subsequent update expires the existing pending update."
    ]
  },
  "why_it_matters": "When scheduling an incomplete Subscription update that should also cancel at the billing period end, set cancel_at_period_end as part of the pending update.",
  "before": "Before this change, passing `cancel_at_period_end` with `payment_behavior=pending_if_incomplete` returned an error.",
