If you want to send a text message to a large contact list on the go, you can save time by sending your message to a dedicated virtual number, which will rebroadcast your message to your list via Zapier.


Before we dive into this Zapier integration, make sure that you have:

  1. A Burst SMS account - Sign up for a free 14-day Burst SMS account
  2. A dedicated virtual number from Burst SMS
  3. A Zapier account - Sign up

Step 1 - Create a new Zap

After you log into Zapier, click on 'Make a Zap!' on your Zapier dashboard.

Step 2 - Choose a Trigger App

Find and select Burst SMS as the trigger app, and then change the 'Trigger Event' field to 'SMS Received to Virtual Number'.

Click on the 'Continue' button below to proceed.

Step 3 - Connect Burst SMS to Zapier

If you haven't connected your Burst SMS account with Zapier, then it will ask you for your Burst SMS API Key and API Secret.

To retrieve your Burst SMS API Key and API Secret, log in and go to Settings and scroll down to the API Settings section.

Note: API Secret is like a password. You'll need to type in your own API Secret, then click the Update Profile button at the bottom of the page. 

Next, paste your API Key and API Secret in Zapier.

Step 4 - Set up Zapier Webhook URL in your Burst SMS Account Settings

Next, copy the Webhook URL that Zapier provides you.

Go to your Burst SMS Account Settings and paste it into the "DLR Callback URL" field. 

For 'DLR Callback Firing,' select 'All Messages'.

Follow the rest of the instructions to make sure that your account has successfully been added to Zapier.

Step 5 - Add Action Send SMS to List

Click on the '+' symbol to add a new Action and select Burst SMS.

Change the 'Action Event' to 'Send SMS to List'.

Follow the steps until you get to 'Set up action' section. Here, in the 'Message' field, find and select the 'Response' variable. This is the variable that stores the message you send to your dedicated virtual number.

Next, under the 'List' field, choose the contact list that you want this message to be rebroadcasted to.

Last but not least, for the 'Caller ID', choose your dedicated virtual number by finding your 'Longcode' variable as seen below.

Now whenever you send a message to your dedicated virtual number, it will rebroadcast your message to the list that you chose.

Once you've tested the integration and you think it's ready to go, your final step is to turn Zap on. Happy messaging!
