Best CBT API for Educational Apps
Computer-Based Testing (CBT) has become the standard for many examinations across Nigeria. From JAMB and Post-UTME to internal school assessments and mock exams, students now expect digital platforms that are fast, reliable and easy to use.
For developers, this presents a huge opportunity.
Whether you're building a CBT mobile app, an online examination portal, a school management system or an AI-powered learning platform, you'll need more than a beautiful interface. You'll also need reliable examination content that can be delivered quickly and consistently.
That's where a CBT API comes in.
Instead of spending months creating and maintaining a database of examination questions, a CBT API lets your application retrieve structured questions, answers and explanations through simple API requests.
In this guide, we'll explain what a CBT API is, what features you should look for and why many developers choose SdashAPI when building educational software.
What is a CBT API?
A CBT API is a REST API that provides applications with examination questions and related data required to power Computer-Based Testing platforms.
Instead of manually entering thousands of questions into your own database, your application requests them whenever they are needed.
A typical response includes:
- Question
- Answer options
- Correct answer
- Detailed solution
- Examination type
- Examination year
- Images (where available)
- Unique question ID
This approach allows developers to launch applications much faster while reducing long-term maintenance.
Why Educational Apps Need a CBT API
Many developers focus on building the application itself but underestimate how much work goes into preparing examination content.
Creating a CBT database usually involves:
- Collecting authentic questions
- Formatting answer options
- Verifying correct answers
- Writing explanations
- Organizing subjects
- Separating examination years
- Updating content regularly
This can delay a project by weeks or even months.
Using a CBT API removes that responsibility and allows developers to focus on building features that improve the learning experience.
What Should You Look for in a CBT API?
Not every API is suitable for educational software.
Here are some features worth considering before choosing one.
Multiple Examination Support
Many educational platforms eventually expand beyond one examination.
Choosing an API that supports multiple exams means you won't have to switch providers later.
SdashAPI currently supports:
- JAMB (UTME)
- WAEC (WASSCE)
- NECO
- Post-UTME
You can explore all supported examinations on the Nigerian Past Questions API page.
Structured JSON Responses
Applications become much easier to build when every request returns predictable JSON.
Developers can focus on creating better interfaces instead of cleaning inconsistent data.
Questions by Subject and Year
Students often prefer to practice specific subjects or examination years.
A quality CBT API should make this possible using simple request parameters.
Detailed Explanations
Students don't just want to know whether an answer is correct.
They also want to understand why.
Including explanations transforms a simple CBT app into a more effective learning platform.
Easy Integration
A modern CBT API should work with popular technologies such as:
- React Native
- Flutter
- React
- Node.js
- Laravel
- PHP
- Python
SdashAPI is designed to integrate with any platform capable of making HTTP requests. Its authentication flow, endpoints and request examples are documented in the official SdashAPI documentation. ([SdashAPI][1])
Why Developers Choose SdashAPI
SdashAPI was built specifically for educational developers.
Rather than providing only raw examination data, it offers a consistent REST API that makes it easier to build and scale educational applications.
Some of the reasons developers choose SdashAPI include:
- Support for multiple Nigerian examinations
- Clean JSON responses
- Questions grouped by subject and year
- Detailed solutions for supported questions
- Easy authentication using an AccessToken
- Well-documented REST endpoints
- Integration with popular development frameworks
Whether you're creating a CBT app for a school, a university admission platform or an AI learning assistant, SdashAPI provides the examination data needed to bring your project to life. ([SdashAPI][1])
Example API Request
curl "https://sdashapi.com/api/v1/q?subject=mathematics&type=utme&year=2023&limit=20" \
-H "AccessToken: YOUR_ACCESS_TOKEN"Example Response
{
"status": 200,
"data": [
{
"id": 4821,
"question": "Which of the following is the chemical formula for table salt?",
"option": {
"a": "NaCl",
"b": "KCl",
"c": "CaCO3",
"d": "NaOH"
},
"answer": "a",
"solution": "NaCl is sodium chloride.",
"examtype": "JAMB",
"examyear": "2023"
}
]
}What Can You Build with SdashAPI?
A single integration can power many educational products, including:
- CBT Practice Apps
- Online Examination Systems
- School Portals
- Student Revision Platforms
- AI Study Assistants
- Mock Examination Websites
- Quiz Applications
- Learning Management Systems (LMS)
As your platform grows, you can continue using the same API for different examination types without redesigning your backend.
