# cancellation_revertable

> Subscription is canceled but the cancellation has not yet taken effect — resume to undo it

|                    |                           |
| ------------------ | ------------------------- |
| **HTTP status**    | `409 Conflict`            |
| **Error code**     | `cancellation_revertable` |
| **Resolve action** | `resume_subscription`     |

## What happened

`POST /v1/organizations/{orgId}/billing/subscription` (select-plan) or `PUT /v1/organizations/{orgId}/billing/subscription` (change-plan) was called on an organization whose subscription is canceled but the cancellation has not yet taken effect — the underlying Orb subscription is still active with a scheduled end date in the future. This is the typical state for paid plans (e.g. Growth) canceled mid-billing-period.

Selecting or changing a plan in this state would strand the still-active Orb subscription with a pending cancellation, so the API rejects the request and points you at the resume endpoint instead.

## How to fix

Call `POST /v1/organizations/{orgId}/billing/subscription/resume` to unschedule the cancellation. This restores `subscription_status` to `ACTIVE` and clears `canceled_at` — no new credit is granted, and the previous plan is preserved. To switch plans after resuming, follow up with `PUT /v1/organizations/{orgId}/billing/subscription`.
