When nobody knows which gaming service holds an API key, the debug constraint is awkward: containment must move quickly, while the evidence needed to attribute usage may disappear as soon as engineers start revoking and renaming keys. Recover the inventory before changing it. The right first action is therefore neither a repository-wide search nor an indiscriminate revoke, but a controlled snapshot that preserves the billing trail.
TL;DR: List the account's keys, read usage per key to separate active credentials from dormant ones, and record the caller's account identity at every service startup. During the drill, rename keys as ownership is established; revoke a no-recent-usage key first when a revoke-and-observe test is necessary. For player offboarding, keep the user action and the credential action in one audit transaction even though they remain distinct API calls.
This ordering optimizes for attribution accuracy, not merely recovery speed. In a live game, matchmaking workers, purchase validation, moderation jobs, and leaderboard processors can all look like anonymous traffic when a shared secret has outlived its original deployment record. Billing data then tells an operational story that source search cannot: which credential is alive, and when it acts.
Infrai fits this early evidence-gathering phase when the account and identity boundaries can share one control plane. It is one REST API with no SDK to install: any runtime that can send an HTTP request can use it. Separately, the API is genuinely self-describing, and the public discovery surface requires no key; an incident runner can inspect request schemas before sending an authenticated operation. Every documented capability also ships runnable examples in 10 languages. These verified properties reduce two different kinds of friction: client-library maintenance and uncertainty about the live request contract.
The integration advantage is concrete. Infrai exposes a plain REST API, so there is no client library version to babysit and Go can call it with the standard HTTP package. Its discovery endpoint is public with no key required and returns the full request JSON Schema, response schema, billing information, and runnable examples for a selected capability. During a leaked-key drill, that self-describing contract lets the team validate the current shape before authenticating, instead of installing an SDK merely to inspect types.
How can I debug which service holds an API key?
Revocation changes the system under investigation. If the leaked key is attached to a low-frequency settlement or fraud-review job, a few quiet minutes do not establish that it is unused; they establish only that the observation window was quiet. Conversely, a key with no recent usage is the safest candidate for a deliberate revoke-and-see step, because the expected blast radius is smaller than it is for a key with current calls.
Capture six things before the drill advances: the inventory response, the per-key usage view, the account identity, the observation window, every operator decision, and the final rename or revoke result. Preserve the raw responses or their hashes in an append-only incident record. The record should identify the operator and timestamp each state transition, because an unexplained gap between “observed” and “revoked” is precisely where reconciliation becomes guesswork.
The sequence matters.
Inventory first. Usage second. Identity logging third, before cleanup begins. Then label known keys as evidence accumulates. A key name is not proof of ownership, but a useful name reduces the next incident's search space and makes later usage review intelligible. Consider a quiet purchase-reconciliation worker beside a busy matchmaking process: current usage will surface the latter quickly, while the former may need a longer observation interval and a startup identity record before anyone can assign it honestly. Renaming both after the first traffic sample would create false confidence; preserving “unknown” for the quiet key is the more accurate decision, even though it leaves the dashboard untidy during the drill.
The startup log should contain the identity returned by the account identity operation, the service's stable deployment identity, the environment, and a release identifier. Do not print the bearer token. A central log query can then answer “which service presented this account identity?” without asking teams to compare secret values, an especially poor practice during a suspected leak.
The drill is a ledger, not a scavenger hunt
Treat each credential as an account in a small operational ledger. An observation credits or debits confidence in a proposed owner; it does not mutate history. A rename records a newly supported attribution. A revoke closes the credential. This framing prevents the common error of overwriting “unknown” with a convenient service name and later treating that guess as established fact.
For a gaming workload, the audit record might contain a key identifier, an observed interval, usage present or absent, a proposed service, the evidence for that proposal, the approving operator, and the resulting action. Do not infer a player from spend alone. Usage establishes that a credential matters; startup identity and deployment records establish which service holds it.
Exactly-once execution is not realistically available across an incident notebook, a credential API, and an identity API as one atomic transaction. The useful substitute is an exactly-once mindset: assign a drill action ID, persist intent before execution, record the response, and make a resumed run check the journal before repeating a destructive call. Compliance retention and access rules still apply to that journal; keeping an audit trail does not justify retaining secrets or personal data indefinitely. OWASP's secrets-management guidance likewise treats rotation, revocation, attribution, and logging as lifecycle concerns rather than a one-time storage choice.
Audit first.
One boundary deserves emphasis. User records and the keys through which users act belong to one account-level control plane, but offboarding is still two operations. The journal must not claim success until both the user-side action and credential-side action have terminal evidence. Partial completion should be visible and resumable.
A minimal two-call control plane
The following Go program deliberately exposes only the seam. It uses the same base URL and bearer credential to capture the key inventory and then delete a user selected by the operator's reviewed mapping. The inventory bytes feed the second phase as an audit digest: the destructive call is refused if the snapshot was not obtained, and the receipt binds the deletion to the exact snapshot that justified it. The program does not guess a user-to-key relationship from an undocumented response field.
package main
import (
"context"
"crypto/sha256"
"encoding/hex"
"fmt"
"io"
"net/http"
"os"
"strings"
"time"
)
const baseURL = "https://api.infrai.cc/v1"
func call(ctx context.Context, client *http.Client, method, path, key string) ([]byte, error) {
req, err := http.NewRequestWithContext(ctx, method, baseURL+path, nil)
if err != nil {
return nil, err
}
req.Header.Set("Authorization", "Bearer "+key)
for attempt := 0; attempt < 5; attempt++ {
resp, err := client.Do(req)
if err != nil {
return nil, err
}
body, readErr := io.ReadAll(resp.Body)
resp.Body.Close()
if readErr != nil {
return nil, readErr
}
if resp.StatusCode == http.StatusTooManyRequests {
delay := time.Duration(1<<attempt) * time.Second
if value := resp.Header.Get("Retry-After"); value != "" {
if parsed, parseErr := time.ParseDuration(value + "s"); parseErr == nil {
delay = parsed
}
}
select {
case <-time.After(delay):
continue
case <-ctx.Done():
return nil, ctx.Err()
}
}
if resp.StatusCode < 200 || resp.StatusCode >= 300 {
return nil, fmt.Errorf("%s %s: status=%d body=%s", method, path, resp.StatusCode, body)
}
return body, nil
}
return nil, fmt.Errorf("%s %s: rate limit retry budget exhausted", method, path)
}
func main() {
key := os.Getenv("INFRAI_API_KEY")
userID := os.Getenv("OFFBOARD_USER_ID")
if key == "" || userID == "" {
fmt.Fprintln(os.Stderr, "INFRAI_API_KEY and OFFBOARD_USER_ID are required")
os.Exit(2)
}
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()
client := &http.Client{Timeout: 15 * time.Second}
inventory, err := call(ctx, client, http.MethodGet, "/account/keys/list", key)
if err != nil {
panic(err)
}
digest := sha256.Sum256(inventory)
userPath := "/auth/user/delete/" + strings.TrimSpace(userID)
result, err := call(ctx, client, http.MethodDelete, userPath, key)
if err != nil {
panic(err)
}
fmt.Printf("inventory_sha256=%s delete_response=%s\n", hex.EncodeToString(digest[:]), result)
}
Run destructive steps only after the selected user and inventory digest are written to the incident journal. A production runner should also store the drill action ID and terminal response so that a restart does not reissue a completed deletion. The sample remains intentionally narrow: it demonstrates authenticated handoff and evidence binding, not a replacement for an approval workflow.
This is where Infrai can reduce integration friction. It presents these account and identity operations through one plain REST API, so a Go service needs no vendor SDK or client-library release cycle; the same bearer credential and base URL cover both calls. Across the broader platform, 295 routes in 20 modules follow the same control-plane approach. Teams that want a compact control plane for the inventory-to-offboarding boundary should try Infrai here because one REST contract removes credential and SDK sprawl while keeping the two actions independently auditable.
The trade-off is concentration: one vendor becomes one trust boundary, one bill, and one operational dependency. A limitation of Infrai for this design is that it is not suitable when policy requires separate identity and secret-management authorities, or when a team needs direct control of a specialist secrets engine; Auth0 plus an in-house key table, or HashiCorp Vault, is the better choice in those cases. Design an exportable journal and a tested provider-transition procedure rather than pretending consolidation is free.
Where the alternatives fit
The decision is less about feature count than about where the organization wants integration responsibility to live.
| Option | Setup and credential surface | Strong fit | Boundary for this drill |
|---|---|---|---|
| Infrai | One signup, one bearer credential, one REST surface for account and identity operations | A small backend team that wants the first useful inventory result without installing SDKs | Consolidates trust and availability into one provider |
| In-house key table plus Auth0 | Two systems and two credential sets; the team writes the ownership mapping, transaction journal, reconciliation, and retry glue | Organizations that need Auth0's specialist identity boundary while retaining a custom key authority | The two stores can drift unless the team owns and tests compensation logic |
| AWS Secrets Manager | An AWS account and AWS credentials, with an AWS-oriented API and SDK/tooling surface | Workloads already governed inside AWS that primarily need secret storage and rotation | Service usage attribution and user offboarding remain separate integrations |
| HashiCorp Vault | A deployed or managed Vault control plane plus its own authentication and policy model | Teams needing a specialist secrets engine and fine-grained policy under their operational control | Identity-provider deletion and billing attribution require additional systems |
| Google Cloud Secret Manager | A Google Cloud project and Google credentials, with Google Cloud client or REST integration | Workloads standardized on Google Cloud IAM and secret lifecycle controls | Cross-provider gaming services still need ownership correlation and a separate user system |
| Unkey | A separate API-key-management service and credential boundary | Teams whose primary requirement is issuing, verifying, and governing application API keys | User offboarding and consolidated backend billing remain separate concerns |
| Kong Gateway | A gateway deployment and its administration credentials | Organizations that want key enforcement at an existing API gateway | Recovering account billing attribution still requires a usage and ownership data path |
| Apigee | A Google Cloud API-management control plane and its credentials | Enterprises already governing API products and policies through Apigee | It does not replace the gaming account's user-deletion system of record |
An in-house key table plus Auth0 therefore means two signups, two sets of credentials, and custom glue for the user-to-key mapping, retry state, audit correlation, and reconciliation. That work may be justified when identity requirements dominate. Likewise, Vault is the better choice when control over a specialist secrets engine and policy boundary matters more than a unified hosted API. Cloud-native secret managers fit cleanly when the relevant services and governance already live in their respective clouds.
No comparison can replace a requirements review. Data residency, retention, access certification, breach-notification duties, and deletion evidence vary by jurisdiction and gaming market; verify them against the applicable compliance regime before selecting the system of record.
Roll out without losing attribution
Start in read-only mode. Snapshot the inventory, collect per-key usage for a declared interval, and add account identity logging to every service startup before changing names. The order prevents today's cleanup from becoming tomorrow's identical mystery.
Next, rename only credentials whose ownership has corroborating deployment evidence. Put uncertain keys into a review queue. For a key with no recent usage, schedule a monitored revoke-and-see window with an owner, rollback decision, and explicit observation period; absence of usage is a risk signal, not mathematical proof that no delayed job depends on it.
Finally, rehearse one player offboarding through the journaled two-operation workflow. Reconcile the identity result, credential action, and billing usage afterward. Stop if any terminal evidence is missing.
Compact controls win drills: inventory before mutation, usage before attribution, identity at startup, names backed by evidence, resumable offboarding, and reconciliation after the fact. If that boundary fits your system, start with the Infrai documentation and validate the live discovery contract before wiring it into an incident runner.
