Creating and Sending SMS Broadcast

This endpoint allows you to create and send multiple SMS messages in a single API request.

Before creating and sending bulk SMS messages you need to:

Create a Subscriber List that contains a column where store the mobile numbers of the subscribers.
Once created the subscriber list, copy the unique identifier of the list ("listId"). This id will help you to send the messages to the subscribers that are added in that list.

In the following request body example, we are going to send this message "Hi [[name]]. This is a test" for each subscriber contained in the list. The message includes a placeholder value. This placeholder can be replaced with dynamic content inside double curly braces ([[...]]) when a message is sent.

Example of a sent SMS message using placeholders:

Hi! {{name}}, your purchase code is {{CODE}}
Hi! Katerina, your purchase code is 242527

📘
NOTE
The placeholder parameter is the name of the column defined when creating the subscriber list. Therefore, the information contained in that column will be sent to each subscriber.

When you create and sending multiple SMS messages (Broadcast), the request body contains the following data:

HTTP Request: POST /broadcasts

{
  "deliveryMethod": "SMS",
  "campaignName": "SMS Broadcast",
  "description": "Sending Broadcast now",
  "listId": 95650,
  "listField": "mobile",
  "message": "Hi [[name]]. This is a test",
  "origin": "14155824559",
  "scheduleWithoutDate": false
}

The parameters presented in the request body example when creating and sending the multiple SMS messages are the following:

Parameter	Required	Description
deliveryMethod	Yes	Specifies the type of delivery channel which the message will be sent: `"SMS"` ,`"EMAIL"`, `"PUSH"`, `"RCS"`, `"WHATSAPP"`. In this case, we enter the `"SMS"` value to send the SMS message.
campaignName	Yes	Name of the campaign, used as the main identifier for the broadcast.
description	Yes	Description of the broadcast.
listId	Yes	Enter the unique identifier of the list which contains the Recipients (subscribers) of the broadcast.
listField	Yes	Name of the column defined when creating the subscriber list that contains the mobile numbers of the subscribers.
message	Yes	Content of the SMS message that will be sent to the subscribers. The maximum length of a short message text is 160 characters using the default GSM 03.38 alphabet. If you use any character that is not in the default alphabet, the message will be encoded in Unicode and will be divided in segments of a maximum of 70 characters each. For example, if you include an emoji in your message and the message is 150 characters long, it will be divided into three segments: the first one with 70 characters, the second one with 70 characters and the third one with just 10 characters. You will be charged per segment, not per message. Placeholder values must be replaced with dynamic content inside double curly braces (`[[...]]`). The placeholder parameter is the name of the column defined when creating the subscriber list. Therefore, the information contained in that column will be sent to each subscriber.
origin	Yes	Source address of the broadcast. Specifies the Shortcode (from 1 to 6 digits), Longcode (from 7 digits on), an alphanumeric shortcode (ex. COMPANY) or a virtual number that will be used to originate and send the SMS message. Any of these codes will appear in the handset as the source of the text message. Virtual numbers will translate to a local shortcode depending on the destination carrier. If you don't have one assigned yet please contact our support team to request one.
scheduleWithoutDate	Yes	Define the Date & Time of your broadcast `true`: Define the date and time when sending the SMS messages. `false`: Send the SMS messages once the API Call is executed. By default is `false`
broadcastDate	No	Applies only when the `"scheduleWithoutDate"` is true. That is, when you want to define the date and time when sending the SMS messages. Set the date and time when the SMS messages will be sent in UTC format: (yyyy-mm-dd-Thh:mm:ss.ssZ). If you do not set the date, the sending of the broadcast will be pending.
segmentId	No	Unique identifier of the segment.
filters	No	Set the filter you want to apply on the message.
filterName	No	Filter Name. The content is the name of the filter applied on the message.
throttle	No	Message delivery speedometer. By default, 250 messages are sent per second.
