Migrating from Twilio to Bandwidth: A Quick Guide

So you’re thinking of migrating from Twilio to a new CPaaS provider. Maybe you’re looking for more control over your call quality, or maybe you’ve outgrown Twilio’s pricing structure; no matter the reason, it’s worth your time to explore Twilio alternatives. Like Bandwidth.

But before you dive into migrating, there are a few things to consider and steps to consider.

Reasons to migrate from Twilio to Bandwidth

There are lots of reasons for your business to migrate from Twilio, but what about why you should migrate TO Bandwidth. Well…


There’s no middleman when you partner with Bandwidth, which means that our costs are often lower than Twilio’s (sometimes by 50%!). Since we own the APIs and our own network we can provide the best rates available, which can save your business big over time.


At Bandwidth, we work with enterprise companies, which means we know what’s needed to help your business scale. As your company grows and needs more volume, our owned network will give you the power and flexibility to grow that other CPaaS providers just can’t provide.


Like Twilio, we offer voice, SMS, and phone number services. That’s not all, though. In addition to the telephony services you’re accustomed to, we also offer 911 Access, group messaging, toll-free SMS, and advanced phone number management functionality that you won’t find elsewhere.

How to get started

So you know you want to migrate, but you’re not sure where to start. Fortunately, it’s as easy as one, two, three.

1.Learn & document the API differences

While our APIs have a lot of the basic in common with Twilio, every provider differs in how they allow users to accomplish tasks. These differences can include incoming calls and messages, number ordering, and hangup events.

Additionally, while just about every CPaaS provider as a VoiceXML (VXML), some also offer a REST API and Callback option. Identifying those differences makes the rest of the process smoother.

2.Determine & scope the necessary changes

Once you’ve identified the differences between our APIs and Twilio’s, it’s time to scope out any changes you’ll need to make. While most of the call logic should remain the same, you should focus time around three main areas:

  • CallState Events
  • Message Events
  • Database changes

These areas tend to have the most variation between CPaaS providers, and focusing there will help streamline your migration.

3.Implement the changes

Time to make the switch! After you’ve completed the evaluation process, you’re ready to implement the changes and complete the migration. A few things to keep in mind:

  • A keen eye for detail is the key to success in making the changes
  • For simple migrations the switch can take as little as a week with a single engineer. More complicated call flows can take a month or so with a team of developers
  • Each ‘call event’ has to be handled somewhere or another; each incoming message will always be sent to a callback URL
  • Don’t forget to check out our SDKs along the way. They can help ease the transition
