The Complete Beginner’s Guide to Voice APIs for Developers

Posted On January 29, 2020 by Alex Macdonald in Blog, SDK

There is a colossal amount of public data that you can access and consume using an API. API is short for Application Programming Interface and it allows you to use the public data available on Twitter, Reddit, Facebook, and countless other web sites.

This blog post covers basic information using APIs to access public data and then will outline some resources to learn more about Voice APIs that can allow you to make voice calls over the internet.

An API is a gateway between you and the data that you want to access. In its simplest usage, you’ll enter an https request in the address bar of your web browser and press Return. The request is formatted to quickly find the data you want and that data is displayed in your browser. 

What are RESTful APIs?

This type of API  is known as a “RESTful” API since you can use a URL to access the data. REST stands for Representational State Transfer. It just means that there are certain rules you need to follow to access data.

The URL is also called a request and the information returned to you is the response. In more complicated examples, you can use such terms as GET, POST, POST and a few other commands to interact with the data.

In most cases, the https request will have “api” in it somewhere to indicate that you are using an API. 

For this blog post, I’m going to show you how to access sunrise and sunset data using an https request to access data from the Sunrise-Sunset organization.

Getting Started

Let’s get started. Working with APIs is extremely fun.

In the address bar of your web browser, you’re going to enter a URL request that looks something like this:

https://api.sunrise-sunset.org/json?lat=20.3484&lng=-57.5522

You can replace the above latitude and longitude with your own or any other location. Once you’ve entered that URL you receive a response that looks a little like this:

{"results":{

"sunrise":"10:27:07 AM",

"sunset":"9:39:11 PM",

"solar_noon":"4:03:09 PM",

"Day_length":"11:12:04",

"civil_twilight_begin":"10:04:02 AM",

"civil_twilight_end":"10:02:17 PM",

"nautical_twilight_begin":"9:37:24 AM",

"nautical_twilight_end":"10:28:55 PM",

"astronomical_twilight_begin":"9:11:00 AM",

"astronomical_twilight_end":"10:55:19 PM"},"status":"OK"}
