API Key Usage Practices

Establish stable API Key usage standards from naming, authorization, validation, rotation, to long-term governance.

Feature Overview

This page no longer explains what an API Key is. Instead, it answers "how to use API Keys stably over the long term". Key topics include:

  • Naming conventions
  • Authorization boundaries
  • Launch validation
  • Rotation and reclamation
  • Long-term audit

Applicable Scenarios

Suitable for the following scenarios:

  • The platform has already started to have multiple integrated systems
  • Different environments need separate key management
  • The team wants to establish unified security standards

Prerequisites

Before you start, we recommend preparing:

  • An environment division plan, such as development, test, and production
  • A list of calling systems
  • A list of people responsible for key custody and rotation

Operation Steps

Step 1: Establish Unified Naming Rules

We recommend that names include at least 3 types of information:

  • System name
  • Environment
  • Purpose

For example: crm-prod-agent-call. This keeps later log review, rotation, and exception investigation costs lowest.

Step 2: Issue Separate Keys for Each Environment

Do not share the same Key across development, test, and production. Otherwise, test leaks, accidental production calls, or troubleshooting will become very difficult.

Step 3: Issue by Least Privilege

Start with the narrowest permissions and expand gradually only when truly needed. In particular, avoid granting the following at the beginning:

  • Access to all Agents
  • Execution of all workflows
  • Full resource management permissions

Step 4: Perform Reverse Validation Before Launch

In addition to verifying "whether calls can succeed", also verify:

  • Whether calls to unauthorized resources are rejected
  • Whether a Key becomes invalid immediately after being disabled
  • Whether behavior is as expected when call frequency is too high

Step 5: Establish Rotation and Reclamation Mechanisms

For Keys used long-term, we recommend defining in advance:

  • How long before expiration rotation occurs
  • Who reclaims it after the system is decommissioned
  • How to urgently disable it after abnormal leakage

Result Validation

After usage standards are established, we recommend regularly checking:

  • Whether there are unclaimed Keys
  • Whether there are long-unused but still valid Keys
  • Whether any Keys have obviously excessive permissions
  • Whether any test Keys are used in production systems

Value Description

The value of these practices is not that they are "more complicated", but that:

  • Keys are identifiable, replaceable, and disableable
  • Responsibility boundaries for integrated systems are clearer
  • Security governance and troubleshooting costs are lower

Notes

  • Do not make Key names too generic, such as test, api, or system
  • Once key standards are established, they should be applied uniformly to all new systems
  • Rotation drills should be completed before a real failure occurs, not designed after a leak
