# vote()

**`vote(...args: VoteInputArgs): Promise<Poll>`**

Submit a vote for a poll.

**Parameters:**

* `...args` (VoteInputArgs): An array containing the following information in order:
  * `pollTypeId` (PollTypes): The type of the poll (SingleChoice or MultipleChoice).
  * `pollId` (EntryIdType): The ID of the poll for which to submit the vote.
  * `optionIds` (EntryIdType\[]): An array of option IDs representing the user's vote.
  * `userId` (string): The unique user identifier.

**Returns:**

* A `Promise` resolving to the updated poll object (`Poll`), including information such as the poll ID, name, creation date, associated poll type, and updated vote counts.

**Example:**

```javascript
const voteArgs = [PollTypes.SingleChoice, 1, [1], 'user-123'];

try {
  const updatedPoll = await pollz.polls.vote(...voteArgs);
  console.log('Vote Submitted:', updatedPoll);
} catch (error) {
  console.error('Failed to submit vote:', error.message);
}
```

The `vote` method allows users to submit their votes for a specific poll. Provide the poll type (`pollTypeId`), the poll ID (`pollId`), an array of option IDs representing the user's vote (`optionIds`), and the unique user identifier (`userId`).

The method returns a `Promise` resolving to the updated poll object (`Poll`), which includes details such as the poll ID, name, creation date, associated poll type, and updated vote counts for each option.

**Note:** Ensure that the provided poll type, poll ID, option IDs, and user ID are valid and correspond to an existing poll in the system.
