I want to send different messages to multiple users at once. I read the article here: https://www.twilio.com/blog/send-bulk-sms-twilio-node-js-html but it mentions nothing about sending customized messages. The only difference in my messages is the user's name.
The best solution I can think of is to create x number of API calls to send messages to x numbers. I believe that's going to be time taking. Is it possible to do it with one API call?

You are right, there is not currently a Twilio service that allows you to send bulk messages with customised messages with one single API call. You will have to make an API call to the messages resource for each message you want to send.
When sending messages in bulk, I recommend you read and understand this article on Twilio rate limits and message queues. That will ensure you are successful in sending your messages.
