# Vote on Proposal

> Submit approval, rejection, or cancellation votes on a proposal

Submits votes on an existing proposal. Multiple signers can vote in a single request.

## Vote Actions

The available action depends on the proposal's current status:

| Status     | Available Actions   |
| ---------- | ------------------- |
| `Active`   | `approve`, `reject` |
| `Approved` | `cancel`            |

## Reject vs Cancel

<Warning>
  `reject` and `cancel` are **not interchangeable**—they operate at different lifecycle stages.
</Warning>

**`reject`** — Block a proposal during voting (status: `Active`)

* Use when you disagree with the proposed action
* Prevents the proposal from reaching approval

**`cancel`** — Stop an already-approved proposal (status: `Approved`)

* Use when circumstances have changed after approval
* Prevents execution of an approved proposal

```
Active → approve/reject → Approved → cancel → Cancelled
                ↓                       ↓
           Rejected                  Executed
```

## Automatic Duplicate Filtering

The API filters out signers who have already voted with the same action. If all requested signers have already voted, the API returns an error.

```typescript theme={null}
// If signerA already approved, only signerB is included
const response = await grid.vote(accountAddress, proposalAddress, {
  signers: [signerA, signerB],
  action: "approve"
});
// response.signers = [signerB]
```

## Permission Requirements

All signers must have `CAN_VOTE` permission (mask includes value 2).
