    "incantation": "When a subscription change should wait for payment, update the Subscription or SubscriptionItem with `payment_behavior=pending_if_incomplete` and `metadata`; Stripe applies the metadata when the pending update resolves, merging keys into subscription metadata.",

      "curl https://api.stripe.com/v1/subscriptions/<SUBSCRIPTION_ID> -u \"<YOUR_SECRET_KEY>\" -H \"Stripe-Version: 2026-05-27.dahlia\" -d payment_behavior=pending_if_incomplete -d \"metadata[<KEY>]=<VALUE>\"",

    "gotchas": [
      "payment_behavior: Optional enum; set to `pending_if_incomplete` to create a pending update when payment fails. Only supported pending-update attributes can be passed.",
      "metadata: Optional key-value object; attach keys to the pending update. Applied to subscription metadata when resolved; new and updated keys merge while unrelated keys are preserved.",
      "<SUBSCRIPTION_ID> (required): ID in the Subscription update path.",
      "<SUBSCRIPTION_ITEM_ID> (required): ID in the SubscriptionItem update path.",
      "<YOUR_SECRET_KEY> (required): Stripe secret API key used for request authentication.",
      "Prerequisite: The update endpoint requires an existing subscription; the SubscriptionItem endpoint requires an existing subscription item. API reference setup examples create a payment method, customer, product, price, and subscription (and a subscription item for the item endpoint).",
      "Prerequisite: `pending_if_incomplete` is for updates, and applies only when payment fails; supported attributes and payment methods are limited.",
      "Metadata is applied when the pending update is resolved.",
      "Existing integrations that do not pass `metadata` are unaffected."

  "why_it_matters": "When implementing a subscription update that should remain pending until payment succeeds, attach metadata to the pending update.",
  "before": "Previously, passing `metadata` with `payment_behavior=pending_if_incomplete` returned an error.",
