# Cancel a Run

`POST /runs/{run}/actions/cancel`

Interrupt a run that is currently planning or applying.

Performing a cancel is roughly equivalent to hitting `ctrl+c` during a Terraform plan or
apply on the CLI. The running Terraform process is sent an `INT` signal, which instructs
Terraform to end its work and wrap up in the safest way possible.

## Path parameters

- `run` string, required

## Request body

- Comment — An optional explanation for why run action was done.
  - `comment` string — The reason.

## Response `202`

Successfully queued a cancel request.

## Other responses

- `204` — Run is already cancelled, nothing should be done.
- `404` — Run not found, or user unauthorized to perform action.
- `409` — Run was not planning or applying. Cancel not allowed.
- `4XX` — Client error.
- `5XX` — Server error.
