e’ve all been there. You’re integrating an API, but the documentation is unclear or incomplete. You end up guessing how endpoints work, misreading responses, and eventually reaching out to support. It’s frustrating and time-consuming.
Now flip that experience. Good API documentation can make a world of difference. It helps developers onboard faster, reduces errors, minimises support tickets, and supports long-term scalability. It’s not just a nice-to-have. It’s the foundation of a great developer experience.
First Impressions Matter
When developers open your API docs, they’re looking for quick wins. They’re far more likely to stick around if they can get a successful response within minutes.
Take Stripe, for example. Their API documentation is consistently praised for its clarity. Developers get sample requests, test keys, error explanations, and language-specific examples. It’s easy to go from idea to working prototype in under 10 minutes.

-d amount=2000 \
-d currency=usd \
-d source=tok_visa \
-d description=”Charge for test@example.com”
Developer Experience Is Everything
from twilio.rest import Client
client = Client(account_sid, auth_token)
message = client.messages.create(
body=”Hello from Twilio!”,
from=”+15017122661″,
to=”+15558675310″
)
Future-Proofing Through Documentation
GitHub gets this right. When they make breaking changes, they publish detailed release notes, timelines for deprecation, and clear instructions for updating. That level of transparency keeps developers confident and engaged.
Good documentation also helps teams onboard new engineers onto older systems and keeps technical debt under control.
Internal Teams Benefit Too
Shopify is a good example of this. They treat internal and external docs with the same care. The result is faster release cycles, fewer bottlenecks, and smoother team collaboration.
