# Delete a field

`DELETE https://studio.grid82.app/v1/apps/{appId}/tables/{tableId}/fields/{fieldId}`

Drop a field and its values after sending its current name as `confirm`.

The field, values, and grants naming it go to the app's trash for thirty days; `trash.restore` can restore them with the same id. Record the app's point-in-time bookmark. The operation returns 409 with readers in `details.impact` until you send `acknowledge=true`; `schema.impact` reports the same impact without changing anything.

Requires the `schema:write` scope. Operation `fields.delete`. MCP tool `fields_delete`. CLI: `grid82 fields delete` (`npx grid82`).
