# Introduction

> RexPay API Documentation (Rewritten for Clarity and Developer Flow)

A reverse-engineered documentation project where I analyzed and rewrote some sections of the [RexPay API documentation](https://rexpay-docs.globalaccelerex.com/docs), focusing on improving clarity, developer onboarding, and content structure.

<Note>
  The pages here are still under construction.
</Note>

### Objective

The goal was to evaluate how effectively RexPay's original API documentation helped developers start quickly, and to **redesign it with clearer steps, better structure, and modern documentation practices** (e.g. using examples, interactive code playground, error handling, and progressive onboarding).

### My Role

* Technical Writer (solo project)
* Responsible for research, information architecture, markdown authoring, and front-end doc presentation.

### **Tools & Stack**

* **Markdown + MDX** - for content formatting
* **Mintlify** - for documentation and deployment
* **Git + VS Code** - version control and workflow

### **Process**

1. **Analyzed the Original Docs**

   * Noted unclear entry point
   * Observed confusing information across pages

2. **Improved Structure**
   * The actual Quickstartpage is not task-oriented
   * Created a **Quickstart** page guiding new developers faster
   * Used consistent headings and spacing (following Stripe’s and OpenAI’s structure)

3. **Polished The API Reference Pages**

   * The API Reference pages are not interactive
   * Most of the reference pages do not touch on errors
   * The HTTP verbs are often not specified
   * Endpoints not properly arranged
   * Code samples are provided in one language (Javascript) only

4. **Published + Iterated**
   * Deployed on Mintlify
   * Shared online for feedback from fellow technical writers and developers

### Before vs After (Key Improvements)

| Feature                 | Original Docs   | Rewritten Version                                                     |
| ----------------------- | --------------- | --------------------------------------------------------------------- |
| **Quickstart flow**     | Reference-heavy | Task-oriented to guide new developers                                 |
| **Code examples**       | Limited         | Multi-language with interactive display to test the code              |
| **Tone**                | Formal & vague  | Action-oriented, developer-friendly                                   |
| **Error Handling Page** | Not available   | Provided a page dedicated to possible errors that developers may face |

### Outcome

✅ Developers can now authenticate and make their first successful API call in a few minutes.
