Apigee is a platform to develop and manage APIs. Apigee was acquired by Google in September 2016 but the core technology first came into existence in 2004. The primary reason for choosing Apigee is to develop user-friendly APIs with modern REST interfaces and access keys. It also includes a ton of monitoring and analytical tools and a lenient security model to help the company take current back-end and expose all of its outside developers. With this write-up, we’ll go through Apigee interview questions and Apigee interview questions and answers for developers.

Ans: Apigee is a software platform for the development and management of APIs. Apigee frontline the services with a proxy layer that provides an abstraction or simulation for your backend APIs to provide, security, rate limiting, analytics, and more. Apigee manages the API gateway and enables easy processes to deploy and create modern friendly applications.
Ans: Apigee consists of the following components:
Ans: Apigee has the availability of the following factors:
Apigee: A hosted SAAS version in which Apigee maintains the environment, allowing you to concentrate on building your services and defining the APIs to those services.
Apigee hybrid: Lets you manage APIs on-premises, on Google Cloud Platform (GCP), or a mix of both.

Ans: Considerations like:
Ans: A web service speaks to a collection of open conventions and principles utilized for exchanging data between applications. Software applications written in different programming languages and running on different platforms can utilize web services to exchange data over computer networks like the internet in a way like between process communications on a single computer.
Ans: The official of a customer to the execution of the service is termed as synchronicity. In synchronous invocations, the customer ends and trusts that the service will finish its activity before proceeding. Asynchronous operations permit a customer to invoke a service and afterward execute other functions.
Ans: No, we cannot have or maintain user sessions in web services as it is stateless.
Ans: API goes about as an interface between two unique applications so they can communicate with one another. An API isn't really web-based. The programming interface may utilize any methods for correspondence to start cooperation between applications.
Web service encourages connections between two machines over a network. It additionally utilizes SOAP, REST, and XML-RPC as methods for correspondence.
All Web services are APIs yet all APIs are not Web services.
A Web service utilizes just three styles of utilization: SOAP, REST, and XML-RPC for communication though API may utilize any style for communication.
Web service in every case needs a system for its activity through an API needn't bother with a system for its activity.
Ans: API is known as Application Programming Interface that is software that enables two applications to interact with each other. It consists of a number of subroutine definitions, logos, and tools to create application software.
Ans: Google Maps API, Amazon Advertising API, Twitter API, YouTube API, etc.
Ans: Numerous APIs have a specific limit set up by the provider. Accordingly, attempt to estimate your use and see how that will affect the general expense of the contribution. Regardless of whether this will be an issue depends on a huge part of how data is utilized. Getting captured by a standard and effectively cut-off as a result of budget limitations will deliver the service (and any framework or procedure relying upon it) virtually useless.
HTTP for client-server communication
XML/JSON as a formatting language
Simple URI as the address for the services
Ans: Web API can be devoured by any customers who support HTTP action words, for example, GET, PUT, DELETE, POST. Since Web API services don't require an arrangement, they can be handily utilized by any customer. In fact, even portable gadgets, for example, cell phones can easily use Web API, which is without a doubt the greatest preferred advantage of this technology.
Ans: API testing is a type of software testing that determines if the created API can meet the expectations related to functionality, reliability, performance, and security of the application.
Test for Core Functionality: API testing gives access to the application without a UI. The center and code-level of functionalities of the application will be tried and assessed right on time before the GUI tests. This will help identify the minor issues which can increase during the GUI testing.
Time Effective: API testing for the most part is less tedious than practical GUI testing. The web components in GUI testing must be surveyed, which makes the testing procedure slower. Especially, API test robotization requires less code so it can give better and quicker test inclusion contrasted with GUI test computerization. These will bring about the cost of putting something aside for the testing venture.
Language-Independent: In API testing, data is traded utilizing XML or JSON. These exchange modes are totally language-free, permitting clients to choose any coding language while receiving automation testing services for the venture.
Simple Integration with GUI: API tests empower exceptionally integrable tests, which is especially helpful on the off chance that you need to perform useful GUI tests after API testing. For example, straightforward incorporation would permit new client records to be made inside the application before a GUI test began.

Ans: There are many protocols available in API testing, such as JMS, REST, HTTP, UDDI, SOAP, etc.
Ans: Setting up the API's test condition isn't a simple errand, so you ought to have a prepared answer if your API testing meeting is coming. The test condition of API is somewhat finished and requires the arrangement of the database and worker, contingent upon the product necessities. No GUI (Graphical User Interface) is accessible in this test structure. At the point when the establishment procedure is finished, API is checked for the best possible activity. All through the procedure, the API called from the first condition is set up with various boundaries to consider the test outcomes.
Ans: Service Endpoint Interface (SEI) is a Java interface class that defines the methods to be exposed as a web service.
Ans: Apigee Edge platform is used for creating and managing APIs. By fronting services with an intermediary layer, Edge gives a reflection or exterior to your backend service APIs and gives security, rate constraining, shares, investigation, etc. I have utilized the intermediary layer of Apigee Edge to process the reaction from API and route to the end-user.
Ans: WS-Security or Web Services Security explains how security measures can be implemented in web services to protect them from any external attacks. WS-Security is a set of protocols that make sure security for SOAP-based messages by the implementation of the principles of security, integrity, and authentication.
Ans: Web services can be made stateful by implementing session management techniques like:
Ans: It includes four parts:
Ans: Idempotent operations mean their result will always be the same, no matter how many times these operations are invoked.
Ans: PUT and DELETE operations are idempotent.
Ans: Get method.
Ans: While performing API testing, the following things should be considered:
