What Should an API Governance Tool Actually Check?

API governance sounds straightforward until an organization has dozens or hundreds of APIs.

At that point, having a style guide isn't enough.

Someone needs to make sure APIs actually follow the rules.

I've been thinking about what an API governance tool should realistically check without turning governance into another bottleneck for developers.

For me, the useful checks fall into a few categories.

1. API Design Standards

The first layer is consistency.

For example:

Naming conventions
HTTP methods
Status codes
Pagination
Error formats
Versioning
Required OpenAPI fields

These are relatively easy to automate when the API contract is described with OpenAPI.

1. Security Checks

Governance should also catch obvious security problems before an API reaches production.

Things like:

Missing authentication
Weak authentication schemes
Exposed secrets
Insecure endpoints
Missing security requirements

Secret scanning seems particularly useful here because accidentally committing credentials is the kind of problem that should ideally be caught automatically.

1. Compliance

This is where governance becomes more organization-specific.

A company may have rules such as:

Every external endpoint must require authentication.

Or:

Every production API must include rate-limiting information.

Instead of relying on developers remembering these rules, an automated governance check can enforce them consistently.

1. Documentation Quality

An API can technically work while still being difficult to consume.

I'd like governance tooling to be able to detect things such as:

Missing endpoint descriptions
Missing parameter descriptions
Missing request examples
Missing response examples
Undocumented error responses

Documentation completeness seems like an underrated part of API governance.

1. Access Control

Governance isn't only about the API definition.

Once multiple teams are working together, organizations also need to control who can access, modify, publish, or administer APIs.

This is where things like RBAC, SSO, and user provisioning become relevant.

1. Auditability

Finally, there needs to be some way to answer:

Who changed what, and when?

Audit logs become increasingly important once APIs are shared across multiple teams.

Without them, investigating an unexpected API change can become surprisingly difficult.

So What Makes a Good API Governance Tool?

I don't think the answer is simply "more rules."

The best governance workflow should catch important problems early, ideally while developers are designing or reviewing an API rather than after deployment.

A useful workflow might look like:

API Design
↓
OpenAPI Validation
↓
Security Checks
↓
Compliance Checks
↓
Documentation Check
↓
Review
↓
Deployment

I've been looking at how platforms such as Apidog approach this by combining governance checks with the broader API development workflow, including RBAC, secret scanning, endpoint compliance, documentation completeness, and audit logs.

What I'm still wondering is how much governance should actually be automated.

For those managing APIs at scale, which governance checks have provided the most value?

And which checks ended up creating more friction than they were worth?
