Exotel supports bulk SMS. The API remains the same as sending a single SMS (see [How to send an SMS](/messaging-apis/sms)). To send bulk SMS, specify an array of "To" numbers instead of a single number — the API contract remains the same.

## Send bulk SMS with static content

[This API](https://developer.exotel.com/api-console/product-sms#send-bulk-static-sms) sends SMSes with the same content to the array of numbers specified in the `To` parameter. To send SMS through the API, you make an HTTP POST request. Refer to the [API reference](https://developer.exotel.com/api/sms#send-bulk-static-sms) for the full contract.

## Send bulk SMS with dynamic content

[This API](https://developer.exotel.com/api-console/product-sms#send-bulk-dynamic-sms) sends SMSes to different numbers with different message content for each number. To send SMS through the API, you make an HTTP POST request. Refer to the [API reference](https://developer.exotel.com/api/sms#send-bulk-dynamic-sms) for the full contract.

A sample PHP bulk SMS code sample is available at [Sample Bulk Code](https://github.com/exotel/ExotelAPI/blob/master/PHP_Samples/sendBulkSms.php).

## Response

Once the APIs are run, you will get a response.

- On success, the HTTP response status code will be `200`.
- The `Sid` is the unique identifier of the SMS. It is useful to log this for future debugging.
