What Are API Testing Services?

API stands for Application Programming Interface, an intermediary of software applications that interconnects a tremendous connection in today’s interconnected world of applications, programs, servers, and websites. API testing performs testing interfaces in internal and external systems so that the functionalities and performance can be tested according to the requirements. API itself is a core baseline specification that behaves as a guaranteed contract of two distinct application pieces.

Vihat Technologies is an application API testing company in India that can help you in your software application directly for its functionality, performance, reliability, and security. Thus, you can effortlessly check the API of your software application quickly and efficiently. Moreover, it is beneficial that APIs can help diverse organizations connect software applications that rely on other applications or services without going through any updates when the dependent software applications periodically or continuously go through some internal changes.


  • Failed to handle invalid conditions: There are possibilities that fail to handle the invalid or incorrect conditions regarding a software application. Then while performing API testing, we can detect such an issue and assist in attaining a solution.
  • Unused flags: There are possibilities where unused flags are left over while developing an application. Our testing service helps detect such unused flags defects, and assists in developing a software application bug-free.
  • Lack of functionality: It is possible to come across issues regarding the lack of functionality that may also lead to defects in software applications. In such cases, we can help detect such functionality issues of that software application during the validation.
  • API connection issues: There is a possibility that connection issues may arise during the development of an application, but it is possible to detect them through our API testing services.
  • Multi-threading issues: Another possibility is that multi-threading issues can make applications more complex and add defects to them; thus, we can help detect such multi-threading issues.
  • False errors: During API testing, our application API testing company can also detect any false errors in an API application.
  • Security issues: It is also possible for security issues to arise, such as user-and-function-level authorization, broken object level, lack of resources, insufficient logging or monitoring, security misconfiguration, etc., which is a matter of concern. Our services can help detect such issues.
  • Incorrect data structuring: It is possible that there might occur some incorrect data structuring in an application. We can help in detecting any such incorrect data structuring in a software application while performing API testing.

Vihat Technologies is a software testing company that provides API testing services so that businesses can enjoy the benefits of testing and focus on developing their software application with high quality and efficient features. Some of the benefits of API testing through our services that businesses can enjoy are as follows:

  • Access to the application without UI:

One of the benefits of API testing services is that it helps to make it easier to access the software application without a user interface. In addition, it’s beneficial for the QA testers since they can get early insights into the errors or defects that will help the developers resolve issues before there is any impact on the GUI.

  • Protection against malicious code and hacking:

API testing is highly beneficial since it helps in protecting the software application from any malicious code and hacking. It removes any vulnerabilities from the software application, which makes it secure. We also possess the ability to make your software application free from any such malicious codes and breakage.

  • Time efficiency:

API testing is a time-efficient method that is faster and quicker than other functional or validation testing processes. API testing services are also beneficial for saving time.

  • Reduces the cost of testing:

This is a less costly means of testing your software application, reducing your cost in different means. Compared to GUI automated testing, it requires fewer codes, which means faster test results that automatically lead to reduced testing costs. It also evaluates errors and issues before GUI testing, which reduces the cost of manual testing. We can help businesses through our highly experienced testers and exceptional tools for API testing and evaluating any errors in an application before GUI testing.

  • Independent technology:

Our application API testing company will be highly beneficial for software applications through its ability to help in selecting technology-independent mark-up language and data-interchange format such as XML and JSON, respectively, and compromised HTTP requests and responses.

  • Fast test execution:

When compared to UI testing, our API testing services have faster releases, and it helps in quick testing execution, which makes it possible for developers to release their application modules faster.

  • Integrates easily with the GUI:

The addition of integration testing with API testing is efficiently possible. So, through the application testing services, it will be beneficial to perform any functional GUI testing after API testing as it easily integrates with the GUI.

We provide application API testing services to our clients through a collaborative testing process in an agile manner. The API testing process of our application API testing company includes:


In this stage, we initiate the task by analyzing requirements regarding the API application. Software or API requirement specification documents help us in the analysis process as an initial part of our services.


In the planning stage, our application API testing company in India writes a precise, clear test strategy and test plan based on the initiation process regarding the analysis of requirement specifications. They serve as a guideline for all the testing processes, schedules, test coverage, etc., throughout the entire software development and testing life cycle.

Test Design

In this stage, we start with the test design, which includes writing and reviewing repeatable test cases according to the requirements determined in the document. Where appropriate, we also focus on non-functional requirements, existing rules, or application logic while writing test cases.

Test Execution

In this stage, we execute the test cases and detect any bugs or flaws in the software and API applications to identify if the requirements are as expected. Here, we also participate in a bug triage meeting to identify and prioritize the most critical defects, along with less critical bugs and gaps. We also get the agreed defects fixed and re-tested before the next testing cycle.


In this stage, we cluster the bugs based on the impact, priority, and severity and report the status of the bugs, test cases, and test cycles as part of our application API testing services.

Results Analysis

In this stage of our services, we analyze the testing reports and discuss with the team the root cause, improvement area, and action plan.


Why does API testing play a key role for businesses?

An offshore application API testing company can perform API testing to ensure the software application’s security standards and ensure that the entire system would perform incredibly under different network conditions or varying loads. Hence, it plays a key role for businesses.

Why choose API testing services over GUI testing services?

When comparing API testing services against GUI testing services, it is noticeable that API testing services by an application API testing company have better coverage of test cycles, save resources, and even enable faster and adequate releases without much hassle. Thus, it is preferable over GUI testing services.

Why is API testing crucial?

Nowadays, APIs have become the primary interface for application logic. An offshore application API testing company, through its API testing, helps in pointing out the potential security flaws; thus, it is becoming more crucial.

Why is there an increment of API testing services across industries?

With the advancement of technologies, even software applications are going through an enhancement phase. Thus, they are becoming more complex in terms of environment, intention, integration, information, and institution. Moreover, the complexities also have complex protocols like JSON, XML, SOAP, etc., with underlying layers. Thus, it is crucial to perform API testing for such multiple layers so that such APIs can function efficiently.
