The Ultimate Dev Portal Checklist: Secure, Scalable, and AI-Ready

Why Dev Portals Are Mission-Critical in 2025

At APIsec|CON 2025, Mikayla Halliwell delivered a talk that every AppSec and DevSecOps professional should bookmark. Dev portals aren't just for documentation anymore—they’re the interface between your organization and the outside world. And when done right, they scale your API program, inspire developer trust, and serve as a powerful security layer.

Whether you're in FinTech, healthcare, or heavy civil construction (as Mikayla is at HCSS), your developer portal is your most visible API product—and your most exposed.

What Is a Dev Portal—and Why Should Security Teams Care?

A developer portal is where developers:

• Learn how your API works
• Generate keys
• Access documentation
• Test endpoints
• Get support

It’s your storefront, help desk, and status board all rolled into one. But it’s also a double-edged sword: expose too much, and you expand your attack surface; expose too little, and developers will abandon your API for a better experience elsewhere.

Dev Portal Essentials: The Secure-by-Design Checklist

Mikayla presented a comprehensive audit framework—here’s what every secure, scalable dev portal must include:

✅ Quick Start Guide

Your portal must offer a frictionless path to “Hello World.” No guide? No adoption.

✅ Key Management

Enable users to generate, rotate, and revoke API keys without calling support. Enterprise users demand self-service security controls.

✅ Postman Collections

Prebuilt collections reduce onboarding time and avoid early API misuse.

✅ CLI Tools

Programmatic access accelerates automation and creates “stickiness” by embedding your API into dev workflows.

✅ Sandbox Environment

Never expose prod to first-time users. A sandbox prevents costly mistakes and demonstrates security maturity.

✅ SDKs in Native Languages

Abstract boilerplate. Reduce friction. Increase adoption.

Documentation That Doesn’t Suck—or Leak

📘 Reference Docs with Swagger/YAML

Cover all HTTP methods, required/optional params, status codes, and authentication flows.

📘 Copy/Paste Code Snippets

Language-switchable, inline examples are now table stakes.

📘 Use Cases & Conceptual Docs

Explain why users should care—business outcomes over endpoints.

📘 Diagrams & Workflows

Visuals for OAuth, webhooks, and data flows help non-coders and AI agents alike.

📘 Requests & Responses

Examples reduce guesswork and debug time, speeding integration.

📘 Endpoints & Parameters

Boundaries are sexy. Well-documented parameters prevent misuse and reduce support tickets.

Security Signals: AppSec Must-Haves in Dev Portals

• Rate Limits: Publish them clearly and enforce them reliably.
• Error Descriptions: A 400 isn’t helpful unless it tells you why.
• API Logs: Show users what was sent, received, and what failed.
• Status Page: Real-time uptime builds trust and reduces ticket volume.
• Alerts & Webhooks: Notify users about quota hits, outages, or deprecations.
• Change Logs: Transparency prevents blind breaks in production.

AI Is Using Your Dev Portal Too

LLMs are now reading your docs—summarizing them, autocompleting requests, and suggesting code. That means:

• Your documentation must be structured, semantic, and AI-parsable.
• GenAI assistants like Treble’s Alfred thrive on well-structured API portals.
• Devs “ask” instead of “search”—and bad structure means wrong answers.

Design for humans, but optimize for AI.

Common Security Concerns

Goran from the audience asked the million-dollar question:

“Does exposing so much increase our attack surface?”

Yes—if you’re careless. Mikayla’s advice:

• Gate access where appropriate
• Measure usage and deprecate unused endpoints
• Limit exposure to documented, secure use cases
• Don’t publish your entire backend as a PDF

Standout Dev Portals to Steal From

• Stripe: The gold standard—interactive docs, clear versioning, full governance.
• Twilio: Copy/paste examples in every language, excellent use case coverage.
• Mapbox: Dynamic docs that respond to parameter input.
• Spotify: Strong OAuth walkthroughs and real-time previews.
• HCSS: Yes, Mikayla’s team. AI-ready, security-forward, and built for enterprise.

Build or Buy? Yes.

You can hand-code a dev portal—or use platforms like:

• ReadMe
• Trellis
• Speakeasy
• Treble

Choose based on your scale, audience, and need for extensibility.

Your Homework: Audit Your Portal

Use this checklist to audit your own dev portal. What’s missing?
What’s half-baked? What’s just plain insecure?

Then do what Mikayla suggests:

• Create backlog tickets
• Steal smart ideas
• Make your dev portal a product, not just a project

Final Word

Developer portals are no longer optional, and they're no longer just for devs. They're API security controls. They're business growth levers. They're AI interfaces.

Make yours count.
