The subscriptionContractUpdate mutation allows you to create a draft of an existing subscription contract. This [draft](https://shopify.dev/api/admin-graphql/latest/objects/SubscriptionDraft) can be reviewed and modified as needed. Once the draft is committed with [subscriptionDraftCommit](https://shopify.dev/api/admin-graphql/latest/mutations/subscriptionDraftCommit), the changes are applied to the original subscription contract.
