Why Developers Hate Writing API Documentation (And How to Fix It)

Introduction

Developers spend an average of 20% of their time writing documentation. That’s a huge number, especially considering that most of us hate this process. Why does this happen?

Problem #1: Documentation is Boring

Developers want to write code, not documentation. Documentation seems less important than functionality and is often postponed.

Real-Life Example

Imagine this situation: you’ve just finished working on a new API endpoint. The code works perfectly, tests pass. All that’s left is to write the documentation… But instead, you move on to the next task, promising yourself to “write it later.” And that “later” never comes.

Problem #2: Documentation Becomes Outdated Quickly

Code changes faster than documentation gets updated. This leads to:

• Integration errors
• Wasted developer time
• API user frustration

Statistics

According to research, 67% of developers have encountered outdated documentation when integrating with APIs.

Problem #3: Manual OpenAPI Writing is a Nightmare

Complex YAML/JSON syntax, typical indentation errors, invalid JSON—all of this makes the documentation writing process painful.

Example of Bad Code

paths:
  /users:
    get:
      summary: Get users
      parameters:
        - name: page
          in: query
          schema:
            type: integer
          # Error: forgot to add required
      responses:
        '200':
          description: Success
          content:
            application/json:
              schema:
                type: object
                properties:
                  users:
                    type: array
                    items:
                      type: object
                      # And so on... lots of nesting

A single endpoint can take hundreds of lines of YAML, and one small error breaks the entire specification.

Solution: Automation with AI

Automation changes the documentation creation process:

1. AI automatically generates field descriptions — you don’t need to think about each field
2. Built-in validation — the system checks specification correctness
3. Quick updates — when code changes, documentation updates easily

Time Comparison

Process	Manual	With Automation
Creating specification	2-4 hours	15-30 minutes
Updating documentation	1-2 hours	5-10 minutes
Validation check	Manual	Automatic

Conclusion

Documentation shouldn’t be a punishment for developers. With the right tools, it can be a fast and even enjoyable process.
