OAuth and IAM setup walkthroughs for API teams

The specific moment: an engineer has been told to add OAuth to an existing API, opens the gateway's auth configuration panel, and finds twelve settings, three of which are labeled with terms they don't fully understand, two of which interact in undocumented ways, and none of which have sensible defaults for their specific use case (machine-to-machine vs. user-facing, internal vs. external consumers). Multiple users across different products independently called out the same two failure points: 'OAuth not easy to set up' and 'IAM policies are very difficult to understand for beginners.' These aren't edge cases — they're the two most common auth requirements for any API.

The gap persists because auth configuration is deeply context-dependent — the right answer for a public consumer API is completely different from an internal microservices mesh — and generic documentation can't make that call for you. Vendors document every option; they never tell you which combination is correct for your situation. No vendor will ship an opinionated auth setup wizard because it requires them to say 'don't use this feature we built' in certain scenarios, which their product teams won't accept.

What gets teams in trouble, per the complaints, is not that the options don't exist — it's that the decision tree is invisible. A team configuring OAuth for the first time doesn't know what questions to ask before they start clicking. They misconfigure, hit an error they can't interpret, and either give up or ring in a senior engineer who's done it before.

This is a business and not a feature because auth configuration is touched by every API team at every company, multiple times per year — every new integration partner, every new internal service, every security audit that requires rotating credentials or tightening scopes triggers a return to this problem. The cost of getting it wrong is a security incident or a broken integration that blocks a customer go-live. Both outcomes are expensive enough that a team will pay to avoid them.

What to build

Build a web-based decision-tree walkthrough that asks six to ten questions about the auth use case (grant type, consumer type, token lifetime requirements, whether the API is public or internal), then generates a step-by-step configuration guide specific to the user's chosen gateway — covering Amazon API Gateway, Apigee, and API7 — with screenshots and exact field values, not general explanations.

Where to start

Launch with Amazon API Gateway OAuth setup only — Cognito integration with API Gateway has a well-documented confusion pattern, the audience is enormous, and a very specific, accurate walkthrough for that one combination will spread organically through developer communities before you expand.

The hard part

Gateway UI and configuration schemas change with product updates, which means screenshots and field-level instructions go stale — maintaining accuracy across three gateways requires either a dedicated update process or a strong community contribution model, neither of which is easy to bootstrap.

How it makes money

Free for the walkthrough generator; charge teams a flat annual fee for a private, embeddable version they can customize and share internally with new hires as part of onboarding runbooks.
