How to make API governance actually manageable

Why most API governance programmes stall

API governance typically starts with good intentions: an internal API catalogue, a review process for adding new integrations, documentation standards, security review gates. It often stalls within a year because:

1. The catalogue is maintained manually and drifts from reality within weeks.
2. The review process adds friction without adding protection — teams route around it.
3. Nobody owns it day-to-day, so it gets updated reactively after incidents rather than proactively.

The fundamental problem is that governance is treated as a documentation exercise. Documentation decays. The only governance that stays current is governance enforced in production.

The gateway as the enforcement layer

A proxy gateway inverts the model. Instead of asking teams to document what integrations they have, the gateway makes undocumented integrations impossible to run. If traffic isn’t going through the gateway, it’s blocked at the network layer. Governance becomes a side effect of normal operation.

In RequestRocket, every outbound integration is a proxy record. The proxy record is the documentation: it names the target, the credential, the region, and the access rules. You can enumerate all integrations at any time:

GET /clients/{clientId}/proxies

Every proxy that exists is a managed integration. Every managed integration has a target, a credential, and at least one rule defining what it’s allowed to do.

Step 1: Define targets explicitly

Targets represent the APIs you connect to. Creating a target is a deliberate record-keeping act:

POST /clients/{clientId}/targets
{
  "targetName": "hubspot-crm",
  "targetBaseURL": "https://api.hubapi.com",
  "targetTestPath": "/crm/v3/objects/contacts",
  "targetRegion": "eu-west-1"
}

The targetRegion field matters for data sovereignty — you can ensure that credentials and traffic for EU customer data stay in EU regions.

Step 2: Credential management as access control

Every integration needs a credential. Requiring credentials to be created through the API (rather than hard-coded in services) means there’s an authoritative record of what secrets exist and what they’re scoped to:

POST /clients/{clientId}/credentials
{
  "credentialType": "target",
  "credentialAuthType": "key",
  "credentialName": "hubspot-private-app-key",
  "credentialRegion": "eu-west-1",
  "credentialSecret": {
    "key": "pat-eu1-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  }
}

The credential is encrypted at rest (AES-256-GCM), it’s never returned in plaintext after creation, it’s never logged anywhere in our platform, and it physically resides in the region / deployment in which it’s being used. Listing credentials shows metadata only — credentialName, credentialAuthType, credentialRegion, credentialCreatedAt — so an auditor can verify the inventory without seeing the secrets.

Step 3: Rules as the access policy record

Rules attached to a proxy are the machine-readable expression of the access policy for that integration. A proxy record without rules is a governance gap — the default effect determines whether unmatched traffic is allowed or denied.

Set proxyDefaultRuleEffect: "deny" universally, then add explicit allow rules that document the intended access:

POST /clients/{clientId}/proxies/{proxyId}/rules
{
  "effect": "allow",
  "methods": ["GET", "POST"],
  "path": {
    "path": { "pattern": "^/crm/v3/objects/(contacts|companies|deals)" },
    "presence": "must_exist"
  },
  "priority": 10,
  "notes": "Sales data sync: read and create contacts, companies, and deals"
}

The notes field is the governance documentation. It lives next to the enforcement rule, so it can’t drift — if the rule changes, the notes change with it.

Step 4: Telemetry as the governance signal

Active governance means knowing when integrations are used, how, and whether anything unexpected is happening. The telemetry API provides this without any additional tooling:

GET /clients/{clientId}/telemetry?interval=day&limit=90

A proxy that hasn’t received a request in 90 days is a candidate for decommissioning — or an indication that the service using it has moved to a different integration path that isn’t going through the gateway.

Unusually high error rates on a proxy can indicate a breaking change in the upstream API that teams haven’t noticed yet. Telemetry turns these from reactive incidents into proactive signals.

Step 5: Preventing new shadow integrations

Once all known integrations are under gateway governance, the last step is making sure new ones can’t bypass it. Network-level controls (egress firewall rules, AWS security groups or VPC endpoints) can block direct outbound connections to known vendor IP ranges, ensuring that all traffic must go through the gateway.

This transforms “we ask teams to create proxy records” (a process that can be skipped) into “traffic doesn’t reach the vendor without a proxy record” (a technical control that can’t be skipped).

Governance as a byproduct, not a project

The goal is a state where:

• Every integration is a proxy record that can be enumerated.
• Every proxy has a credential that can be audited.
• Every proxy has rules that document and enforce the access policy.
• Every call is logged and its telemetry is queryable.

When you reach that state, governance isn’t a quarterly report someone has to compile — it’s a live view of your API estate that’s accurate by construction.

If your API governance programme is mostly spreadsheets and good intentions, the gateway layer is where you close the gap between documented and enforced. Read the RequestRocket documentation or start for free.
