An application programming interface API is an interface implemented by a software program to enable interaction with other software, much in the same way that a user interface facilitates interaction between humans and computers. What is an API? APIs are implemented by applications, libraries and operating systems to determine the vocabulary and calling conventions the programmer should employ to use their services.

By using third party APIs in your products or services, you have access to a ton of useful features — such as authentication or storage services — that can benefit both you and your users.
The full source code of this project will be available at the end of part 2. A good summary can be: Our application is a simple contact list service that manages contacts with linked notes. It has two object types, contacts and notes. Each contact has basic attributes such as first name, last name, and email address.
Also, each contact can have a number of markdown-formatted notes linked to it. This can be seen as the equivalent of wireframing for visual applications. The full list of methods is displayed below: Our custom classes are under the namespace of API and sit inside the lib directory.
At this point our working directory structure would look like this: The share directory contains data such as logs, configuration files, the SQLite databases and dump files, and the SSL certificates. The bin directory contains utility scripts that create the database and import some data using the provided.
This simplifies the authentication logic and prevents poorly configured clients to access non encrypted endpoints. The easiest and more logical way to set this up is acting directly on the web server or through a proxy server.
For more information on how to create a self signed certificate an install it on your Apache see this article on SSLShopper.
Bootstrap and Front Controller As said before, the bootstrap. For example the statement: Then, after some refinements you can see them in the sourceI get the generated log writer and try to connect to the database: Cache the innermost ; ContentTypes: We will write all these except for the pre-existing ContentTypes.
The file is loaded by our front controller index. Routing structure Slim has a nice feature called Route Groups.
With this feature we can define our application routes like this: This middleware is run first in the chain so it is added as last, and it takes an optional root path parameter in the constructor.
The verify method is protected so that it can be overridden by child classes; my version here is simple: You can modify or extend this class to inject your own authentication logic or use an OAuth module. We need a minimal payload that contains an error code and message.
In addition, validation errors require more breakdown. We need a way to give a useful error to the client without exposing too much of our internal mechanism in order to avoid security flaws. The custom ValidationException class has a custom getData method that returns an array of validation errors that are added to the final payload.
On the API side we can have a simple error like this: Meet the author Vito Tardia Vito Tardia a. Ragmanis a freelance web designer and full stack developer. He works for various types of clients, from small and medium businesses to well-known web agencies.

API documentation (API docs) or API specifications (API specs) On-line or hardcopy descriptions of the API, intended primarily for programmers writing in Java.
These can be generated using the Javadoc tool or created some other way. Generally, a help authoring tool is the best way to generate documentation for multiple targets.
And ff you are a Windows user, HelpNDoc is one strong candidate to consider as it will generate multiple documentation formats from a single source, including. DO YOU WANT TO BUILD AND WRITE GLORIOUS TECHNICAL DOCUMENTATION FULL TIME? EMAIL [email protected] NEED YOU.
Beautiful Docs. I love documentation. If you work with/are writing code intended for usage and consumption by more than one person, you should love it, too.
Developers often have a certain user persona in mind when they write documentation. They make assumptions about API consumers' knowledge base and how much they're willing to put up with to get a good understanding of how the API works.
