Unmatching product

Error message

Unmatching product

What it means

Thrown by the Lemonsqueezy license validator after a license key validates successfully against the Lemonsqueezy API, but the returned meta.product_id is not in the product_ids list fetched from the app's remote config. It prevents a valid-but-wrong-product key (e.g. a key for a different app/SKU) from granting entitlements in this product.

Solutions

1. Verify the license key is the one issued for THIS product (check the purchase email/product name).
2. Ensure the device is online so remote config product_ids is current — a stale/empty list can exclude a valid product_id.
3. If remote config is correct and the key is genuinely for this product, contact support to reconcile the product_id mapping.

const allowedProductIds = (await remote.getRemoteConfig('product_ids')).product_ids
// cannot fully pre-validate without the key's product_id, but ensure remote config loaded:
if (!allowedProductIds?.length) console.warn('product_ids remote config missing; mismatch error likely')

function isLemonsqueezyActivationResponse(json: unknown): json is { meta: { product_id: number }; instance: { id: string } } {
  return !!json && typeof json === 'object' &&
    typeof (json as any).meta?.product_id === 'number' &&
    typeof (json as any).instance?.id === 'string'
}

try {
  await activateLicense(key)
} catch (e) {
  if (e instanceof Error && e.message === 'Unmatching product') {
    // tell user the key is for a different product; ask for the correct key
  }
  throw e
}

When it happens

Trigger: activateLicense/checkLicense succeeds at the Lemonsqueezy layer, then `remoteConfig.product_ids.includes(json.meta.product_id)` is false. Common when a user pastes a license key bought for a different product/bundle.

Common situations: User owns multiple Lemonsqueezy products and pastes the wrong key; remote config product_ids was updated but the user's cached key is from a legacy product; a resold/shared key is for a different SKU.
