## Introduce concatenatedOriginContract to subscriptionLine

As of 2025-01, we've introduced `concatenatedOriginContract` to `subscriptionLine` .

You can now query the origin contract of the lines if you have used the Subscription Billing Cycle APIs to combine multiple contracts. This can be accessed through `subscriptionBillingCycle.editedContract.lines.concatenatedOriginContract`.

Learn more about combining contract on [Shopify.dev](https://shopify.dev/docs/apps/build/purchase-options/subscriptions/contracts/combine-subscription-contracts).
