Bandwidth Consumer Preferences Survey
Read the research report
Read theShort Message Service (SMS) is the most widely used form of text messaging—leveraging both wireless and traditional telecom infrastructure to transmit, while being universally accessible across mobile devices. Any software developer can use an SMS application programming interface (API) to easily integrate messaging (both sending and receiving) into their software without complicated telecom infrastructure or knowledge.
An SMS API works similarly to any other application programming interface that triggers API calls to utilize a functionality like sending or receiving a text message. These SMS API callbacks, also called webhooks, are extremely robust allowing for customization of messaging services within an application, limited only by the imagination.
A successful integration to Bandwidth’s SMS API is usually managed by a software developer programming in a modern programming language. Traditionally, an integration involves some level of testing, data modeling, and server configuration to communicate with Bandwidth’s texting API. Most web developers are able to build a test integration in under a day, with production integrations scaling in time with the complexity of the messaging service.
The best SMS APIs can integrate with most modern programming languages that have the ability to reach the web. Bandwidth provides SDKs for PHP, C#, NodeJS, Java, Ruby, and Python.
Yes, for NodeJS, Java, Ruby, Python, PHP, and C#.
No. If you need access to our SMS API for proof of concept development or testing, please request a trial account.
An SMS gateway allows you to use your existing SMPP servers to send messages without having to migrate your infrastructure to the cloud. You can learn more about Bandwidth’s SMS Gateway.
Using a texting API allows you to add the ability to send and receive text messages to your application or software without the need for expensive telecom infrastructure. With just a few lines of code your customers can be texting from with your application.
Yes. Every message you send costs money, which is why having a high message deliverability rate is so important for getting a good ROI. Visit our Message Deliverability page to learn more about what impacts deliverability, how to calculate ROI, and how to improve your deliverability.
No, but our SMS API allows you to build the solution that’s right for you and your customers. Whether that includes sending, receiving, or both, our texting API enables you to power the right solution for you.
Yes. Bandwidth supports both plain text messaging (SMS) and rich media texting (MMS). For other rich media options, check out RCS beta.

Depending on the type of number you use, there are limitations to the number of messages that can be sent per second (also known as MPS). Person-to-Person use cases are typically limited to about 1 MPS, while Application-to-Person channels can have much higher MPS rates based on your specific needs. Talk to a member of our team to learn more and to find out how Bandwidth can meet your messaging needs.
