A repository of the technical terms and jargon intrepid Twilio developers may encounter on their building journey.
An Application Programming Interface (API) is provided by a service or program so that others may use the features and functions of the system. APIs are like a contract that describes how a consumer will make requests of the system, and what they will receive in return.
C# (pronounced "see sharp") is a computer programming language created by Microsoft for use on the .NET platform. It is an object oriented programming (OOP) language and is statically typed. Its name comes from the C language, from which it inherits a similar syntax.
Call Tracking is a software-based performance marketing technique that generates and assigns a unique phone number to a specific advertisement or marketing campaign. Call Tracking systems then follow and analyze leads through that phone number “channel” to understand the channel’s true effectiveness and ROI or receive a commission for driving that lead.
Call whisper, also commonly referred to as call screening, involves playing a message to the callee while the caller continues to hear ringing. It can provide additional information such as the source or purpose of the call to the callee before the call begins and even allow the callee to accept or reject the call based on that information.
Interactive Voice Response (IVR) is an automated telephony system that interacts with human callers through the use of voice and touch-tone keypad selections (DTMF tones). It’s also commonly known as a phone tree.
Masked calling is a technique used in ecommerce to protect buyers' and sellers' personal phone numbers private. It uses a short-lived phone number for each party, allowing them to communicate seamlessly during a specified time period. After the time period has expired, the numbers are recycled and reassigned to other parties on the platform, which helps keep transactions from happening outside the platform.
The PSTN (Publicly Switched Telephone Network) is the network that carries your voice calls when you call from a landline or cell phone. It refers to the worldwide network of voice-carrying telephone infrastructure, including privately-owned and government-owned infrastrucure.
A REST API allows software programs to expose functionality and data to other programs over the Internet in a consistent format. APIs are considered RESTful if the means of accessing the API provider's functionality adhere to the architectural style of REST.
A software development kit, or SDK, is a downloadable software package that contains the tools you need to build on a platform.
A short code is a special 5 or 6 digit telephone number that's shorter than a full phone number. Short codes are used to send and receive SMS and MMS messages to and from mobile phones.
A Voice API is a tool for software developers to make and receive phone calls with a simple, easy to understand API. Behind the scenes, a Voice API bridges the Public Switched Telephone Network (PSTN) and applications connected to the internet. By using a Voice API, software developers can program voice calling into their applications without specialized telecommunications knowledge and hardware.
Voice Proxy is also known as Masked Calling. It refers to the technique used to protect users' private information by providing an intermediary number so that neither party can see the other's true phone number for voice calls or SMS.
Voice Over Internet Protocol (VoIP) is a category of hardware and software that enables voice calls to be made and received over the internet.
Webhooks are user-defined HTTP callbacks. They are triggered by some event in a web application and can facilitate integrating different applications or third-party APIs, like Twilio.
Web Real-Time Communication (WebRTC) is a collection of communications protocols and APIs originally developed by Google that enable real-time voice and video communication over peer-to-peer connections.
A WebSocket is a persistent bi-directional communication channel between a client (e.g. a browser) and a backend service. In contrast with HTTP request/response connections, websockets can transport any number of protocols and provide server-to-client message delivery without polling.
