🔍 How to Explore and Understand an API

Before writing technical content about an API—whether a use case, tutorial, or setup guide, you need to understand how the API works.

This guide will help you explore a public API endpoint confidently and extract the insights you need to create clear, accurate, and developer-friendly content.

1. Understand the goal of the API endpoint

Start by answering these questions:

  • What does this API endpoint do?
  • Who would use it, and in what real-world situation?
  • What problem does it solve?

Tip: Look for real-life scenarios in fintech, gig work, e-commerce, or international transfers that match the API’s purpose.

2. Read the official documentation

Go through the official Chimoney API docs for your selected endpoint. Focus on:

  • Authentication: What type is required? API key? Bearer token?
  • Endpoint Method & URL: Is it a GET, POST, or other method?
  • Parameters: What inputs are needed (path, query, or request body)?
  • Example Requests: Are there code samples you can try?
  • Example Responses: What data is returned?

Take notes on anything that is unclear or undocumented. You’ll either clarify it in your writing or note it as a limitation.

3. Test the endpoint yourself

Use tools like:

When testing:

Step What to Check
Authentication Do you need to pass a token or key?
Parameters Are they required or optional? What formats work?
Responses What does a success response look like? What about errors?
Edge Cases What happens if you pass a wrong or missing parameter?

Tip: Save your test results. You’ll reuse these in your tutorial or setup guide.

4. Identify setup requirements

This is especially useful for writing your setup guide later.

Look for:

  • API keys or tokens needed
  • Base URL and headers
  • Required libraries or SDKs
  • Account or developer access setup
  • Test vs production environment differences

Write down every prerequisite someone else would need before they can start using the endpoint.

5. Prepare Your content plan

Once you're familiar with the API:

  • Use your testing experience to build a relevant use case
  • Walk through your steps again to shape your tutorial
  • List and explain your setup process in a beginner-friendly setup guide

Quick checklist

  • I understand what this API endpoint does and who needs it
  • I have reviewed its required inputs and outputs
  • I’ve successfully tested the endpoint using sample data
  • I’ve documented the authentication, setup, and error behavior

If you can check all the above, you're ready to start writing!
