REST API Design Rulebook
A REST Application Programming Interface (REST API) is a type of web server that enables a client either user-operated or automated to access resources that model a system’s data and functions This book is a REST API designer’s style guide and reference It proposes a set of rules that you can leverage to design and develop REST APIs |

REST API Developer Guide
Many GET RESTful APIs support sorting using the following syntax without the line breaks: https:///api/endeavour/trigger?sort=[{\"property\":\"name\"\"direction\":\"ASC\"}{ \"property\":\"date\"\"direction\":\"DESC\"}] 3 10 Filtering Filtering of results is supported |
Should you download PDFs from an API?
In modern web applications, it is often necessary to download PDFs from an API. In fact its a core feature in many everyday applications. It could be as often as downloading a bill receipt of your last trip via Uber, resume templates online, or notes from your email.
What is PDF extract API?
PDF Extract API leverages AI technology to accurately identify text objects and understand the natural reading order of different elements such as headings, lists, and paragraphs spanning multiple columns or pages. Extract font styles with identification of metadata such as bold and italic text and their position within your PDF.

A Frame of Reference
When talking about APIs, a lot of the conversation focuses on abstract concepts. To anchor ourselves, let's start with something that is physical: the server. A server is nothing more than a big computer. It has all the same parts as the laptop or desktop you use for work, it’s just faster and more powerful. Typically, servers don't have a monitor,
What An API Is and Why It's Valuable
Websites are designed to cater to people's strengths. Humans have an incredible ability to take visual information, combine it with our experiences to derive meaning, and then act on that meaning. It's why you can look at a form on a website and know that the little box with the phrase "First Name" above it means you are supposed to type in the wor
How An API Is Used
When two systems (websites, desktops, smartphones) link up through an API, we say they are "integrated." In an integration, you have two sides, each with a special name. One side we have already talked about: the server. This is the side that actually provides the API. It helps to remember that the API is simply another program running on the serve
Chapter 1 Recap
This chapter focused on providing some foundational terminology and a mental model of what an API is and how it is used. The key terms we learned were: Server: A powerful computer that runs an API API: The "hidden" portion of a website that is meant for computer consumption Client: A program that exchanges data with a server through an API cdn.zapier.com

Knowing the Rules
People create social etiquette to guide their interactions. One example is how we talk to each other on the phone. Imagine yourself chatting with a friend. While they are speaking, you know to be silent. You know to allow them brief pauses. If they ask a question and then remain quiet, you know they are expecting a response and it is now your turn
The Protocol of the Web
There is a protocol for just about everything; each one tailored to do different jobs. You may have already heard of some: Bluetooth for connecting devices, and POP or IMAP for fetching emails. On the web, the main protocol is the Hyper-Text Transfer Protocol, better known by its acronym, HTTP. When you type an address like http://example.com into
HTTP Requests
Communication in HTTP centers around a concept called the Request-Response Cycle. The client sends the server a request to do something. The server, in turn, sends the client a response saying whether or not the server could do what the client asked. Figure 1. The Request-Response Cycle. To make a valid request, the client needs to include four thi
URL
URLs are familiar to us through our daily use of the web, but have you ever taken a moment to consider their structure? In HTTP, a URL is a unique address for a thing (a noun). Which things get addresses is entirely up to the business running the server. They can make URLs for web pages, images, or even videos of cute animals. APIs extend this idea
Method
The request method tells the server what kind of action the client wants the server to take. In fact, the method is commonly referred to as the request "verb." The four methods most commonly seen in APIs are: GET - Asks the server to retrieve a resource POST - Asks the server to create a new resource PUT - Asks the server to edit/update an existing
Headers
Headers provide meta-information about a request. They are a simple list of items like the time the client sent the request and the size of the request body. Have you ever visited a website on your smartphone that was specially formatted for mobile devices? That is made possible by an HTTP header called "User-Agent." The client uses this header to
Body
The request body contains the data the client wants to send the server. Continuing our pizza ordering example above, the body is where the order details go. A unique trait about the body is that the client has complete control over this part of the request. Unlike the method, URL, or headers, where the HTTP protocol requires a rigid structure, the
HTTP Responses
After the server receives a request from the client, it attempts to fulfill the request and send the client back a response. HTTP responses have a very similar structure to requests. The main difference is that instead of a method and a URL, the response includes a status code. Beyond that, the response headers and body follow the same format as re
How APIs Build on HTTP
By now, you can see that HTTP supports a wide range of permutations to help the client and server talk. So, how does this help us with APIs? The flexibility of HTTP means that APIs built on it can provide clients with a lot of business potential. We saw that potential in the pizza ordering example above. A simple tweak to the request method was the
Instructions
Send a GET request without any body data. Send a POST request and type your favorite kind of pizza in the body field. Send a PUT request and type a new ingredient to add to your pizza in the body field. Send a DELETE request without any body data. cdn.zapier.com
Next
In the next chapter, we explore what kind of data APIs pass between the client and the server. NOTES 1. The HTTP specification actually requires a request to have a URI (Universal Resource Identifier), of which URLs are a subset, along with URNs (Uniform Resource Names). We chose URL because it is the acronym readers already know. The subtle differ
Representing Data
When sharing data with people, the possibilities for how to display the information is limited only by human imagination. Recall the pizza parlor from last chapter — how might they format their menu? It could be a text-only, bulleted list; it could be a series of photos with captions; or it could even be only photos, which foreign patrons could poi
JSON
Many new APIs have adopted JSON as a format because it's built on the popular Javascript programming language, which is ubiquitous on the web and usable on both the front- and back-end of a web app or service. JSON is a very simple format that has two pieces: keys and values. Keys represent an attribute about the object being described. A pizza ord
How Data Formats Are Used In HTTP
Now that we've explored some available data formats, we need to know how to use them in HTTP. To do so, we will say hello again to one of the fundamentals of HTTP: headers. In Chapter 2, we learned that headers are a list of information about a request or response. There is a header for saying what format the data is in: Content-Type. When the clie
Chapter 3 Recap
In this chapter, we learned that for two computers to communicate, they need to be able to understand the data format passed to them. We were introduced to 2 common data formats used by APIs, JSON and XML. We also learned that the Content-Type HTTP header is a useful way to specify what data format is being sent in a request and the Accept header s
Instructions
Send a request with: Content-Type header = "application/json", Accept header = "application/json", and data format = "XML". Send a request with: Content-Type header = "application/json", Accept header = "application/json", and data format = "JSON". Ok, now just try changing things around and seeing what happens :) cdn.zapier.com
Next
In the next chapter, we find out how two computers can establish trust using Authentication in order to pass along sensitive data, like customer details or private content. Notes: 1. http://en.wikipedia.org/wiki/XML Things are starting to pick up in our understanding of APIs. We know who the client and server are, we know they use HTTP to talk to e
Identities in a Virtual World
You've probably registered for an account on a website before. The process involves the site asking you for some personal information, most notably a username and a password. These two pieces of information become your identifying marks. We call these your credentials. When you visit the website again, you can login by providing these credentials.
Basic Authentication
The logging-in example above is the most basic form of authentication. In fact, the official name for it is Basic Authentication ("Basic Auth" to its friends). Though the name has not garnered any creativity awards, the scheme is a perfectly acceptable way for the server to authenticate the client in an API. Basic Auth only requires a username and
Authorization.
Figure 1. The Authorization HTTP header. When the server receives the request, it looks at the Authorization header and compares it to the credentials it has stored. If the username and password match one of the users in the server's list, the server fulfills the client's request as that user. If there is no match, the server returns a special stat
