Subscriptions

Update a subscription

Patches metadata on a subscription: name, description, trial period, billing flags, subscription-level discount, spending thresholds, price escalation, and tags. This endpoint does not modify the priced item set. To change items, see the Updating a Subscription examples. When an edit of a sent subscription saves its terms but the offer is not reissued with them, the call fails with a message that says so and the terms stay saved but cannot be signed; send this request again with an empty body to retry issuing the saved terms. On an active or paused subscription, a change of auto-renewal, the renewal period, payment terms, additional terms or terms of service applies as a subscription change, which can need approval. When the change needs approval, the call fails with the pending approval flow in the error’s approval object: approval.change_id names the subscription change that waits for it and approval.flow_id names the flow, and the subscription’s open_change reports the same change. While a change is open on the subscription, the call fails with approval.reason open_change and approval.change_id; repeating it returns the same answer until a dashboard user approves, rejects or withdraws that change.
