API Testing is the process of testing Application Programming Interfaces (APIs) to ensure that they are working correctly and achieving the expected results. APIs are integral for any software applications to communicate with each other, as they provide data exchange and flow of information between different applications. A qualified API Testing Expert can ensure that the communication between applications is secure, and that they meet the performance requirements of the end user.

API Testing Experts make sure to think like an “attacker” while performing API operations, while they expand the boundaries of API inputs to test. This involves traditional testing methods such as boundary value analysis, API workflow validations, boundary conditions and security patch testing. In addition their skills involve overseeing the debugging of API logical codes, assisting in 4GL programming related tools, creating automated API tests & scripts as well as load and stress test API process flows.

Here’s some projects that our API Testing Experts has made real:

  • Creating automated tests for backend services
  • Identifying security loop holes in APIs
  • Debugging API logic codes and component layers
  • Developing customized load tests for optimal performance
  • Integrating third party services via APIs

Overall, a qualified API Testing Expert can provide comprehensive and reliable solution for your application software. These experts can fine tune your application software to ensure that it meets all system requirements and user demands efficiently. By hiring an experienced freelancer from Freelancer.com you can secure superior performance of your application software maintained in perfect condition. We invite you to post your own project on Freelancer.com today and get ready to hire an expert API Tester!

    Necesito poner en marcha una app catcher de pruebas funcionales completamente automatizadas para mi aplicación y quiero que la ejecución sea lo más ágil posible, prácticamente en milisegundos. El proyecto consiste en desarrollar un script ―o la solución que consideres óptima― capaz de lanzar, validar y reportar pruebas funcionales de forma fiable. No estoy casado con herramientas concretas como Selenium, Appium o Cypress; si crees que otra tecnología, framework o lenguaje es más adecuado para conseguir la mejor velocidad y estabilidad, adelante. Entrego casos de uso claramente definidos, datos de prueba y acceso al entorno de staging. Espero, a cambio: si puede mejor Api que es mas rápido, el objetivo 1 es dar GO Y...

    I need a seasoned QA specialist to put my web application through its paces, concentrating on two core areas: overall functionality and the user interface. All testing must be carried out in Google Chrome, as that is where the bulk of my users will interact with the product. If you spot issues that only appear in other browsers, you’re free to note them, but Chrome is the primary focus. The job covers everything from validating key user flows and edge-case scenarios to making sure the layout, styling, and on-screen messages look and behave exactly as intended. I will provide access credentials, a short onboarding guide, and any additional assets you might need. Deliverables I expect: • A concise test plan outlining the scenarios you covered • A detailed bug report (in...

    I need an expert to stand up the full SMS and messaging setup inside my existing Twilio account and then stitch it together with a WhatsApp Business API connection handled through 360dialog. Here is what I want to walk away with: • A correctly configured Twilio Messaging Service (numbers, sender IDs, compliance rules) that can send and receive SMS. • A live 360dialog WhatsApp Business API instance tied to the same customer database, ready for production traffic. • Clean API wiring so my app can decide: send on WhatsApp first and, if the user is unreachable, fall back to Twilio SMS. • Sample code and clear documentation that show how to trigger messages, parse incoming webhooks, and monitor delivery. If you have done a dual-channel rollout like this before, ...

    Our corporate-style website needs a thorough WCAG 2.2 AA accessibility audit from top to bottom. I have not singled out any specific problem areas yet; instead, I want a complete, independent scan that highlights every success criterion we pass or fail, followed by clear, practical guidance on how to fix anything that falls short. Here is what I expect to receive: • A detailed technical report covering automated test results (e.g., Axe, Lighthouse, WAVE) and manual checks with screen readers and keyboard-only navigation, mapped against each WCAG 2.2 AA success criterion. • An executive summary that tells non-technical stakeholders where we stand today and the overall conformance level. • A prioritized remediation roadmap describing exactly what to change in our code, ...

    I need a detail-oriented tester who can move comfortably between hands-on manual checks, structured API exercises, and careful data entry while I finalise a USSD menu for release. The core goal is data accuracy: every figure pulled from, written to, or displayed by the system must be proven correct. Here is how the work breaks down. • Web and desktop builds of the product both require functional sweeps. You will follow existing user stories, expand on them where gaps appear, and record every deviation in a concise bug report. • Our REST endpoints need repeatable validation. Feel free to use Postman, JMeter, or another tool you prefer, but make sure assertions cover all status codes, payload structures, and edge-case parameters. • During each round of testing you will e...
