How to get Messaging service SID from your Twilio account

To send messages through Twilio acccount, we need a Twilio messaging service with phone number attached to it. Twilio Messaging service is a pool of sender phone numbers having the same features and configurations. It helps in 2 major use cases,

1. Sending to candidate's around different geographical regions. For example - if you want to send to both US and Indian numbers, you can add one sender number for US and one sender mobile number for India in the same messaging service and twilio will automatically choose the number belonging to the nearest region to send to your end users
2. Managing the scale of your notifications. In case of high message volumes, twilio distributes your outbound messaging traffic evenly across the phone numbers in your Messaging Service so that the delivery doesn't get affected

You can refer to Twilio's excellent documentation on messaging service to know more about it

On "Buy a Number" page:

3. Click on "Search". This will load the list of available numbers with SMS capability in your region and the price of each number listed in a table.

If you are new to Twilio, your trial account is initially funded with enough money to purchase a phone number, so you won't have any expenses while completing this guide.

You may be asked to comply with the regulatory requirements associated with the number — thorough regulatory documentation is provided by Twilio. Be sure to use your number responsibly and comply with any requirements.

On "Messaging Services" page:

1. Click on "Create Messaging Service" button

3. The next step is to add the number that we have bought to this messaging service

One of the platform advantage of using SuprSend as a central communication system is that it shows notification analytics for all channels in your SuprSend account together.

By default SuprSend Webhook URL is configured in Twilio. This will help you to track the message delivery status and failure logs on SuprSend dashboard. If you have a requirement where you would want to get the DLR reports in your backend, contact us at [email protected]

Vendor switching not supported

Vendor switching from Twilio to any Indian vendor is currenly not supported due to DLT restrictions. So, if you are using twilio as your default vendor for any of the communication type, you'll not be able to choose a different vendor in other communication type. Though choosing a different vendor in other workspace will still be supported
