海外TECH	DEV Community	A Guide to the Most Popular Types of APIs: REST, SOAP, GraphQL, and gRPC	https://dev.to/pragativerma18/a-guide-to-the-most-popular-types-of-apis-rest-soap-graphql-and-grpc-4ail	A Guide to the Most Popular Types of APIs REST SOAP GraphQL and gRPCAPIs are the most important component of the modern day software development process helping applications and services communicate and transfer crucial information However with the advancements in the field now there are various choices to go with REST SOAP GraphQL or gRPC That means whether you are an application architect or a backend developer it s essential that you understand which APIs are the best suited to particular applications Each API type has its unique architecture which evolved in response to the needs of the time And as technology has evolved and our relationship with technology has altered we ve seen APIs arise to cover new gaps and serve new uses In this article we ll look at how SOAP REST GraphQL and gRPC APIs compare to each other to give you a sense of their pros and cons common use cases and other considerations when you re choosing the best one for your needs REST APIsREpresentational State Transfer REST is a software architectural style for developing APIs to provide a simple uniform interface These can be used to make data content algorithms media and other digital resources accessible via web URLs allowing them to be consumed via the web mobile and device applications They allow data exchange in simple formats such as JSON and XML REST APIs adhere to the following six specific architectural constraints A uniform interfaceCompletely statelessNative cachingClient server architectureA layered systemThe ability to provide executable code to the clientHere s an example of a REST API message car vin KNDJTAA make kia model soul year links service cars KNDJTAA service sell cars KNDJTAA sell clean cars KNDJTAA sell ProsREST APIs are based on the HTTP protocol which means they are format agnostic allowing you to utilize XML JSON HTML and other formats This makes REST APIs quick and lightweight which is essential for mobile app development internet of things devices and other applications REST APIs can be discovered easily from the URL thus they are very easy for the developers to test and integrate with their applications REST APIs are stateless hence they are very flexible to use as well as highly scalable as per the use case These APIs can be developed in Python JavaScript Node js Ruby C and a variety of other languages making them more accessible to most developers ConsOne downside of RESTful APIs is the loss of the ability to maintain a state such as within sessions It may also be more challenging to utilize for novice developers REST does impose any security thus it is appropriate for public URLs but it is not good for confidential data exchange between the client and the server There is no binding contract on the structure of communication As a result when it comes to execution there is a lot of back and forth which can lead to unnecessary frustration and bottlenecks You can use API Tester to create and send your first REST API request and see for yourself how it works SOAP APIsThe Simple Object Access Protocol SOAP is a protocol for sharing information encoded in Extensible Markup Language XML between a client and an Internet based operation or service It can be used with various transport protocols such as HTTP FTP SMTP etc SOAP is commonly used in conjunction with the Web Service Description Language WSDL The importance of WSDL is that it allows developers and machines to analyze a web service that supports SOAP to learn about the nuances of information exchange over the network Furthermore the WSDL explains how to format the SOAP request and answer messages supported by the provided service SOAP is utilized for enterprise level web services requiring high security and complicated transactions SOAP is frequently used in APIs for financial services payment gateways CRM software identity management and telephony services A SOAP message has a hierarchical structure with the lt soap Envelope gt as the root element Three child elements can be added to the root element These are the child elements lt soap Header gt lt soap Body gt and lt soap Fault gt Here s an example of a SOAP message POST Quotation HTTP Host www xyz orgContent Type text xml charset utf Content Length nnn lt xml version gt lt SOAP ENV Envelope xmlns SOAP ENV SOAP ENV encodingStyle gt lt SOAP ENV Body xmlns m gt lt m GetQuotation gt lt m QuotationsName gt MiscroSoft lt m QuotationsName gt lt m GetQuotation gt lt SOAP ENV Body gt lt SOAP ENV Envelope gt ProsSOAP is completely programming language and processing platform agnostic because of the standardized format SOAP APIs come with built in native error handling helping developers quickly identify and resolve problems SOAP APIs are the best suited for transferring sensitive data to and fro such as financial data as its standardization allows a specific contract to be imposed in form of code throughout all of the APIs Stateful operations are supported by SOAP and may be implemented using the WS Web Services Specifications which are built on top of the basic XML and SOAP standards ConsBecause SOAP can only send messages as XML files your SOAP API will be less performant as XML is a more verbose format than JSON SOAP API requests to your server consume more bandwidth and take longer to process the request and return the result to the client SOAP client server communication is based on WSDL Web Service Description Language contracts implying a close connection As a result it is not suitable for loosely connected applications since you cannot avoid a contract between the client and the server SOAP also has a steeper learning curve is more difficult to develop and cannot be tested in a web browser as opposed to REST SOAP requires you to construct contracts in WSDL establish client stubs adhere to tight requirements and more As a result as a programmer you will have less flexibility in choice API Tester supports sending requests to SOAP APIs and allows you to test your APIs without any effort in a quick and easy way GraphQL APIsWhen Facebook created GraphQL they required a robust data fetching API that could perform all of Facebook s tasks while being straightforward and easy to learn and use by their product developers GraphQL was created in order to rebuild Facebook s native mobile apps GraphQL is a query language It returns a query in the form of a string which is then submitted to a server The server processes the query and delivers the response to the client in JSON format GraphQL is a strongly typed language in which each level of a GraphQL query corresponds to a different type and each type represents a different set of accessible fields As a result it is similar to SQL in that it offers informative error warnings prior to performing a query hence the name GraphQL has a hierarchical structure in which relationships between objects are defined graphically Every object type represents a component in this context and every related field from one object type to another represents a component wrapping another component A simple GraphQL request looks like this me name friends name When migrating from a monolithic backend application to a microservice design the GraphQL API may assist us in managing communication between numerous microservices by integrating them into a single GraphQL schema ProsGraphQL is significantly faster than other communication APIs because it allows you to narrow down your request query by selecting only the data you wish to query Thus it resolves all over fetching and under fetching problems Using GraphQL s API we can integrate numerous platforms It brings them together while masking their complexities The GraphQL server is also used to retrieve data from existing systems and package it in GraphQL response format This is especially useful for legacy infrastructures or third party APIs that are massive in size and difficult to manage When we send GraphQL queries to the server the server responds in a simple secure and predictable format As a result it makes it easier for you to construct a customized query based on your needs This makes GraphQL extremely simple to learn and use At a higher component level we can share the GraphQL fields used in many queries for reuse This feature is known as fragments and it allows you to obtain diverse data while maintaining the same schema field Because the result set or returned data in GraphQL is highly particular to the client s query it is quite straightforward and easy for the server to generalize it When we add new product features or fields to the server it has no effect on old clients You can continue to utilize the older server without concern because server fields can be deprecated but still operate This compatible procedure does not necessitate the use of an ever increasing version number As you can see Facebook uses the same version of GraphQL API in all of its applications ConsOne downside is that queries always return an HTTP status code of regardless of whether they were successful or not If your query fails your return JSON will include a top level errors key containing error messages and a stack trace This can make error handling considerably more difficult and add to the complexity of things like monitoring It is more complicated to implement a simplified cache with GraphQL than to implement it in REST Rate limiting is another issue with GraphQL In REST API you can easily write we accept just this many requests in one day but in GraphQL this sort of statement is harder to convey GraphQL is difficult to pick up without lots of training and experience GitHub s GraphQL API is the most commonly used free developer API Create and run a GraphQL request in API Tester within minutes and get started to explore more gRPCgRPC Remote Procedure Call gRPC is a cross platform open source contract based communication protocol that streamlines and controls interservice communication by providing a set of functions to external clients The g at the beginning indicates that this is the most advanced version created by Google in On one side a user will pick a remote process to run serialize the required parameters and then attach any additional information to the message This is then transferred to the server which communicates with the other application decoding the message and performing the action The original user is then given a result ProsIt is simple and straightforward GET is used to fetch information and POST for everything else Functions are simple to add and for lightweight payloads overall performance is excellent Thus it is endlessly customizable due to the flexibility to define any type of function ConsThe fact that gRPC is strongly connected to the underlying system limits its reusability in many circumstances is where it falls short Furthermore no abstraction layer exists between the API and the real system functions which raises security problems How to Choose the Right API for Your Use As you might be able to guess from the above discussion there is no “best API type each of the API types have its distinct characteristics that make them well suited for specific applications However the question still remains how to find the one that works the best for you Here are some questions that can help you determine Which programming language would you like to use Which environment will you be developing in What is the most important functionality for this API What skills do you have on staff What skills can you acquire What resources have you set aside for this project Remember that you can always run a simple proof of concept with one or two types to test how they work You can also use API Tester an easy to use mobile app that helps you to test any API on your phone ConclusionWe hope this blog post was helpful in distinguishing between the most popular types of APIs Each has a purpose and when you make a deliberate and considered selection up front you re well on your way to designing an API that is not just effective but also resource conscious	2022-11-26 15:07:56
