# POST /v1/{+name}:split

`POST /v1/{+name}:split`

Splits capacity commitment to two commitments of the same plan and `commitment_end_time`. A common use case is to enable downgrading commitments. For example, in order to downgrade from 10000 slots to 8000, you might split a 10000 capacity commitment into commitments of 2000 and 8000. Then, you delete the first one after the commitment end time passes.

## Request body

- SplitCapacityCommitmentRequest — The request for ReservationService.SplitCapacityCommitment.
  - `slotCount` string, int64 — Number of slots in the capacity commitment after the split.
