# createBulk()

Creates multiple [`WaitlistEntry`](https://clerk.com/docs/reference/backend/types/backend-waitlist-entry.md)s in bulk for the given email addresses.

If an email address is already on the waitlist, no new entry will be created and the existing waitlist entry will be returned.

```ts
function createBulk(params: WaitlistEntryBulkCreateParams): Promise<WaitlistEntry[]>
```

## Example

> Using `clerkClient` varies based on the SDK you're using. Refer to the [overview](https://clerk.com/docs/reference/backend/overview.md) for usage details, including guidance on [how to access the `userId` and other properties](https://clerk.com/docs/reference/backend/overview.md#example-get-the-user-id-and-other-properties).

```tsx
// Each object in the array represents a single waitlist entry
const params = [
  {
    emailAddress: 'user1@example.com',
  },
  {
    emailAddress: 'user2@example.com',
    notify: true,
  },
]

const response = await clerkClient.waitlistEntries.createBulk(params)
```

## Backend API (BAPI) endpoint

This method in the SDK is a wrapper around the BAPI endpoint `POST/waitlist_entries/bulk`. See the [BAPI reference](https://clerk.com/docs/reference/backend-api/tag/waitlist-entries/POST/waitlist_entries/bulk){{ target: '_blank' }} for more information.
