What Is a REST API? Examples, Uses, and Challenges Postman Blog

REST APIs can be designed with certain security mechanisms that ensure that only authenticated and authorized users can access them. Common REST API authentication methods are HTTP basic authentication, JSON web tokens, OAuth, and API keys. In addition to requesting resources, clients can use REST APIs to modify and even add new items on a server using HTTP methods.

For REST services, the server typically performs resource identification by using a Uniform Resource Locator . A URL is similar to the website address that you enter into your browser to visit any webpage. The URL is also called the request endpoint and clearly specifies to the server what the client requires. Clients are users who want to access information from the web. The client can be a person or a software system that uses the API.

  • In this scenario, Zomato requests location access from Google Maps through APIs, and a response is sent to Zomato from where we can track the location.
  • Hevo loads the data onto the desired Data Warehouse/destination and enriches the data and transforms it into an analysis-ready form without having to write a single line of code.
  • Web Service uses a collection of open-source protocols to exchange data between applications whereas API acts as an interface between two applications to facilitate interaction with each other.
  • The machine that gives the resource to the client is also called the server.
  • In RESTful APIs It is multi-layer and has a transport protocol which makes the system less secure when compared with REST.
  • He realized that on the Web only a transport protocol, a naming scheme for stuff as well as a well defined exchanged format is needed to exchange messages or documents.
  • This works because it lets us lean back into the world of being pragmatic.

Security– Security is an additional benefit because API supplements an extra layer of protection between your data and server. As API enables businesses to open their applications’ data and functionality to external third-party developers, it eventually grows business partnerships, driving more revenue. Easily load data from multiple sources like REST APIs to the Data Warehouse of your choice in real-time using Hevo Data. In basic authentication, the client sends the user name and password in the request header. It encodes them with base64, which is an encoding technique that converts the pair into a set of 64 characters for safe transmission. REST API requests might include data for the POST, PUT, and other HTTP methods to work successfully.


These documentation therefore is the truth and thus defines the API a client can look up or even use to autogenerate stub classes to interact with the server-side, similar to SOAP. REST APIs communicate via HTTP requests to perform standard database functions like creating, reading, updating, and deleting records within a resource. For example, a REST API would use a GET request to retrieve a record, a POST request to create one, a PUT request to update a record, and a DELETE request to delete one.

In contrast, REST API gets executed even if users do not know the function names and the parameters in a specific order. You can contribute any number of in-depth posts on all things data. From this blog, you would now know about APIs, REST APIs, and RESTful APIs. You will be able to appreciate the basic and key differences in the REST vs RESTful battle. The CRUD operations and Endpoints of REST RESTful APIs will be clear to you now.

On the other hand, HTTP API is an application that communicates between two systems using the Hypertext Transfer Protocol. HTTP APIs make endpoints available as API gateways, allowing HTTP queries to connect to a server. But, do you know the differences between HTTP API vs REST API? When you discuss two resource types there, i.e collection and single, and explain why we should provide different responses to these resource types , I understand your suggestion above. The media type identifies a specification that defines how a representation is to be processed.

What is REST and REST API

Server applications aren’t allowed to store any data related to a client request. In this approach, the server assigns a unique generated value to a first-time client. Whenever the client tries to access resources, it uses the unique API key to verify itself. API keys are less secure because the client has to transmit the key, which makes it vulnerable to network theft. Unlike POST, sending the same PUT request multiple times in a RESTful web service gives the same result.

GitHub REST and GraphQL API are returning different data

APIs act as a mediator between two applications which provides interactions between them. API is a bigger umbrella, and REST API is a unique type of API prevalent among mobile and cloud applications. No API is void of disadvantages, but new developers find REST API difficult because it fails to maintain the state within sessions. As modern APIs have emerged as a product that adheres to specified standards and specific audiences, businesses have improved their user interfaces quickly. The primary goal of API is to standardize data exchange between web services. Depending on the type of API, the choice of protocol changes.

They give more context about the response and include information such as the server, encoding, date, and content type. OAuth combines passwords and tokens for highly secure login access to any system. The server first requests a password and then asks for an additional token to complete the authorization process. It can check the token at any time and also over time with a specific scope and longevity. The response contains information that tells the client whether the request was successful.

The working of RESTful is completely based on REST applications. REST APIs work by fielding requests for a resource and returning all relevant information about the resource, translated into a format that clients can easily interpret . Clients can also modify items on the server and even add new items to the server through a REST API.

Securing a REST API also starts with industry best practices, such as using hashing algorithms for password security and HTTPS for secure data transmission. An authorization framework like OAuth 2.0 can help limit the privileges of third-party applications. Using a timestamp in the HTTP header, an API can also reject any request that arrives after a certain time period. Parameter validation and JSON Web Tokens are other ways to ensure that only authorized clients can access the API. When possible, resources should be cacheable on the client or server side. Server responses also need to contain information about whether caching is allowed for the delivered resource.

What does the RESTful API client request contain?

This strict adherence results in efficient REST APIs after their development. Roy Fielding, in his dissertation, has nowhere mentioned any implementation direction – including any protocol preference or even HTTP. Till the time, we are honoring the six guiding principles of REST, which we can call our interface – RESTful. Ideally, everything needed to transition the resource state shall be part of the resource representation – including all the supported methods and what form they will leave the representation. Remember that hypertext does not need to be HTML on a browser.

Machines can follow links when they understand the data format and relationship types. Every addressable unit of information carries an address, either explicitly (e.g., link and id attributes) or implicitly (e.g., derived from the media type definition and representation structure). REST uses resource identifiers to identify each resource involved in the interactions between the client and the server components. The downloaded code simplifies clients by reducing the number of features required to be pre-implemented.

Are There Other API Styles Besides REST?

The bearer token is typically an encrypted string of characters that the server generates in response to a login request. The client sends the token in the request headers to access resources. Request headers are the metadata exchanged between the client and server. For instance, the request header indicates the format of the request and response, provides information about request status, and so on. They simplify and decouple various server components so that each part can evolve independently. Platform or technology changes at the server application do not affect the client application.

It’s sometimes referred to as a contract between an information provider and an information user—establishing the content required from the consumer and the content required by the producer . Using python data structures will work great and might get a bit tough while dealing with other objects. So to solve this problem, flask-restful provides us with a module called fields and marshal_with() decorator. api testing best practices These are similar to WTForm, so you can use the fields module to describe the response structure and make the code simple to understand. REST is a popular style of web API, and it’s used to communicate data between devices and servers. Different data is contained in different parts of the API requests and responses, and this course explains what those different parts are and how to document them.

API developers can design APIs using several different architectures. APIs that follow the REST architectural style are called REST APIs. Web services that implement REST architecture are called RESTful web services. However, you can use the terms REST API and RESTful API interchangeably. An API gateway is an application programming interface management tool that sits between a client and a collection of backend services.

Cloud applications

Using RESTful API, an application can access the information from data sources like Databases using the REST API methods discussed above. Hevo Data, a No-code Data Pipeline, helps load data from any data source such as Databases, SaaS applications, Cloud Storage, SDK,s, and Streaming Services and simplifies the ETL process. Hevo loads the data onto the desired Data Warehouse/destination and enriches the data and transforms it into an analysis-ready form without having to write a single line of code. Hevo supports robust and native connectors for REST APIs to help you unify data with ease. In an HTTP request, these CRUD methods are used to access and use data.

You can also change the underlying technology on either side without affecting the communication. A client-server architecture made up of clients, servers, and resources, with requests managed through HTTP. Flask-RESTful uses view methods to understand multiple kinds of return values.

The Future of REST RESTful API

In my thought, most of my APIs are pretty REST-ful, but it’s not 100 percent. This is because the main purpose of a Web page’s function is to request different resources that make up a page. In REST-based APIs, we leverage these verbs to describe the types of operations we want. REST is an architectural style that uses simple HTTP calls for inter-machine communication instead of more complex options like CORBA, COM+, RPC, or even SOAP. Using REST means your calls will be message-based and reliant on the HTTP standard to describe these messages.

Resources can be images, videos, text, numbers, or any type of data. The machine that gives the resource to the client is also called the server. Organizations use APIs to share resources and provide web services while maintaining security, control, and authentication. In addition, APIs help them to determine which clients get access to specific internal resources.

REST is a set of rules or guidelines to build a web API.It is basically an architectural style for networked applications on the web which is limited to client-server based applications. We defined an API and gave an example to help explain its meaning. We also got to know some of the methods provided by REST to create, read, update and delete data stored on the server. Image SourceAs REST uses HTTP verbs methods for communication, these methods are self-explanatory. In addition, REST architecture helps increase developers’ productivity, allowing them to display the information on the client-side and store or manipulate the data on the server-side.
