Release a reservation
The reservations.release operation: POST /api/v1/reservations/{id}/release in the REST API and the reservations_release tool in the MCP server.
/api/v1/reservations/{id}/releaseGives what a reservation still holds back to the wallet (each part to the credits it came from) and closes it
as released. Releasing a released reservation returns it unchanged; a captured or expired one can't be
released (reservation_not_open). Releasing changes no balance: the credits only stop being held.

Errors
| Code | HTTP status | When | What to do |
|---|---|---|---|
validation_failed | 400 | id isn't a reservation ID (res_…). | Fix the fields listed in details.issues and send the request again. |
resource_not_found | 404 | This brand has no such reservation in this mode. | Check the ID and that your credentials are scoped to the right organization, entity, brand and mode. |
reservation_not_open | 409 | The reservation was already captured or expired. | Create a new reservation. A reservation is closed once it is captured, released or expired (details.status). |
version_conflict | 409 | The wallet changed at the same moment (another reservation, capture or grant); retry. | Fetch the object again and retry the change. |
scope_required | 400 | The request names no brand (an org or entity key without Ownrecord-Brand). | Call the operation with credentials or a target at its level: an organization, a legal entity, a brand or the platform (details.required_scope). |
permission_denied | 403 | You can't change this brand's wallets (wallets:write: owners, admins and support). | Ask an organization owner or admin for a role or scope that allows this action. |
livemode_not_allowed | 403 | You have no live-mode access, so you can't use live wallets. | Use test mode, or credentials for the target's mode. Developers need live access granted by an organization owner or admin. |
