Every developer should be familiar with the term
API
which is the convention for connecting software systems or between different components.
API
Especially with the growing popularity of mobile applications and microservices architectures,
API
are the key to their success, and how
API
are designed and developed is especially important, and today's article is a complete
API
development guide that describes content, tools, and best practices in the development of
API
API
whose full name is
Application Programming Interface
is an application programming interface that is a set of instructions, standards, or requirements that enable software or applications to take advantage of the capabilities/services of another application, platform, or device for better service. I
n short, it allows applications to communicate with each other.
For example, when we use Alipay and WeChat APP, we request data on the background server through the API and display it on the APP.
API
is the basis for all applications that process data or initiate communication between two products or services. I
t enables mobile applications or platforms to share their data with other applications or platforms and simplifies the user experience without involving developers. M
ost importantly,
API
eliminates the need to build a similar program or platform from scratch. Y
ou can use some other applications/existing applications in the platform.
For these reasons, both application developers and business leaders focus on
API
development.
Before we dive into it, let's look at the basic terms that make it easier for you to understand the concept.
Header
or parameters, the authorization code passed to the request is
API Key
API
interacts with another system, both ends of the communication channel are considered
Endpoint
API
request parameters and response principals.
HTTP
METHOD OF THE
RESTful API
FOR OBTAINING RESOURCES.
HTTP
method of the
RESTful API
to create resources.
REST
(Representative State Transfer) is an implementation of a programming architecture that provides communication efficiency between two devices/systems.
It is lightweight, he shares data by reference rather than copy of the data, and the system created based on this architecture is called the
RESTful
system, and the most famous example of
RESTful
system is the World Wide Web.
SOAP
or simple object access protocol is a message protocol that shares structured information when performing
Web
services on a computer network.
It is used in conjunction with
XML
information sets and application layer protocols such as
HTTP
and
SMTP
for message formatting and message negotiation and transport, respectively.
API
from the request to the response process.
API
rate limiting is the process of defining the rate at which end users can access the
API
This means limiting the number of requests a user can send to the
API
at a time.
API
over a specific period of time is called a current limit.
This can be used for
API
restrictions, such as setting a daily limit of 1,000
API
requests, and when a user clicks on 1001 requests, the server returns an
HTTP
status code of
429
with a message that says "Too many requests."
If you open some travel apps/websites to book your flight, fill out the form - enter the departure and return dates, city, flight and other relevant details - and submit them. In just a few seconds, a list of flights and prices, time, seat availability and other details are displayed on the screen.
To provide such rigorous data, the platform sends requests to airlines' websites to access their databases and obtain relevant data through
API
In response to the
API
api-to-platform data, the platform displays it on the screen, as follows:
Here, flight booking applications/platforms and airline websites act as endpoints
EndPoint
while
API
act as intermediaries to simplify the data sharing process. W
hen talking about endpoint communication,
API
takes two forms,
REST
and
SOAP
Although both approaches can lead to effective results, mobile app developers today prefer
REST
to
SOAP
because
SOAP API
are heavy and platform-dependent.
Here's how to develop an API? Which tools and technologies are selected?
There are many tools and techniques available during
API
development, and here are a few popular tools for developing APIs for developers:
Google
API
management tool that helps developers and entrepreneurs succeed in digital transformation by re-establishing
API
approach.
SDK
and snippets in
API
formats and convert them into other specifications, such as
RAML
API Blueprint
and more.
API
internal and external APIs.
PHP
framework for
Web API
development.
API
API
management program that incorporates
IOT
technology into the process.
Git
repository that hosts code services that can submit code, publish requests, and version control.
You can also save your code in a private repository.
API
tool chain that enables developers to run, test, document, and evaluate the performance of their
API
API
should allow users to search for data based on different criteria, such as dates, and be able to modify (update, edit, and delete) the retrieved data, and record the timestamp of the modification.
API
should be able to determine how much data is displayed at a time and the total number of pages, and should also inform the end user of the number of data pages remaining.
API
should authorize users to sort data based on the timing of the modification or other criteria.
RESTful
style for effective
API
development.
REST API
are stateless and lightweight.
In addition,
JSON
syntax is similar to that of most programming languages, which makes it easy for mobile application developers to parse it into any other language.
API
need to be exposed, they also need to be licensed through
OAuth
- you can do it with the click of a button.
Dos攻击
API
keys, and
OAuth
apps, you must consider
API
gateway as the best point to implement them.
Only the right, legitimate users can access the data that follows, and the
API
can be analyzed and managed by encrypting messages or editing private messages at the gateway.
GET
and
POST
methods, you need to have
RESTful API
overwrite
HTTP
method, and you can use the automatic
HTTP
header
X-HTTP-Method-Override
API
server has memory leaks,
CPU
exhaustion, or other problems?
With this in mind, there are tools you can use to evaluate and troubleshoot the
API
API
can be formatted using
OpenAPI
specifications so that other application developers can easily understand the entire process and leverage this information to provide a better user experience.
In summary, good
API
documentation reduces project time and provides efficiency in
API
development.
The above is a guide document on API development, I hope to help you. To learn more, take a look at the documentation
