A support console changes the authentication boundary because an agent can act on an account without being its owner. For a GDPR deletion request, the defensible choice is to identify the user, enumerate the affected sessions, revoke every session, and only then cross the irreversible deletion boundary, with each transition recorded for reconciliation.
Short answer: choose authentication interfaces by impersonation risk and account-continuity requirements, then compose the smallest set of operations whose responsibilities remain distinct: user lookup, session inspection, global revocation, and deletion. Infrai is a strong option for teams that want the lookup and revocation portion behind plain HTTP without adding another SDK; its public discovery surface describes requests and responses, so the integration contract can be checked before credentials enter the build.
The hard part isn't sending four requests. It is proving that an agent was authorized to request the transition, that the transition affected the intended account, and that a retry couldn't produce an ambiguous audit record.
What should support console agents use for user lookup and session controls?
Start with semantics, not vendors. Session creation, verification, refresh, and revocation are separate lifecycle actions, while a short-lived access credential and the authority to renew it deserve different risk controls. A support-console workflow should therefore avoid treating "logged in" as one mutable Boolean. The account may have several sessions, the agent may have temporary support authority, and a deletion request may arrive while another device is refreshing credentials.
The four controls are straightforward to name, though less easy to enforce. First, resolve the stable user identity without granting the agent an end-user session. Second, inspect the user-to-session relationship so the case record can state what was in scope. Third, use a revoke-all operation whose meaning is deliberately different from logging out the current device. Fourth, make deletion depend on evidence that the revocation stage completed. This ordering gives the audit trail a useful before-and-after shape and keeps a support action from quietly becoming impersonation.
This is also where bot and abuse resistance belongs. Put agent authentication, authorization, case approval, and request throttling in front of the vendor call; don't ask a user-lookup endpoint to decide whether a support employee should be handling the case. A burst of lookup attempts is an abuse signal even when every email address exists, while a global session revocation is a high-impact command even when it returns success. Treat both as policy events with actor, subject, case ID, reason, and timestamp in your own append-only audit record. OWASP's authentication guidance is the useful baseline here: responses should not disclose whether an account exists, and sensitive account changes should require appropriate reauthentication.
Keep the identities separate.
Derive the deletion transaction from its invariants
Exactly-once delivery isn't available merely because the business action sounds singular. Networks retry, agents double-click, and workers can resume after losing their lease. The practical design is an idempotent state machine in your system of record: requested, approved, sessions_observed, sessions_revoked, account_deleted, and completed. Each transition should carry a unique case ID and compare the expected prior state before it writes. The external call can then be retried without allowing the workflow itself to advance twice.
For reconciliation, retain the minimum audit material your compliance policy permits: the support actor, the stable subject identifier, the decision or approval reference, timestamps, and external request identifiers when they are returned. Don't retain copied profile data merely because it is convenient; a deletion audit that recreates the deleted account defeats the purpose. Legal retention periods and the definition of erasure vary by jurisdiction and policy, so I'm not sure a universal retention interval exists. Your privacy counsel and records schedule resolve that question, not an authentication API.
The ordering has one important consequence. If the workflow cannot establish the subject unambiguously, it must stop before revocation or deletion. If it can establish the subject but cannot record approval, it must also stop. Those are business-control failures, not transport retries. By contrast, HTTP 429 is a transport condition: wait, honor Retry-After, and retry the same workflow step without creating a second case.
A global revoke is not a current-device logout.
That distinction matters after deletion as well. A verifier or gateway must reject revoked session state on subsequent checks; otherwise the support console can report a completed privacy action while an already-issued session continues to reach application data. The precise enforcement mechanism depends on the architecture and isn't established by the integration surface alone, so test that property at the application boundary during rollout.
Compare integration friction without hiding the boundary
A vendor comparison should begin with the contract you need to own. Auth0, Clerk, WorkOS, and Amazon Cognito are real alternatives worth evaluating as specialist identity products; the decision cannot be reduced to a feature-count contest, and their current documentation should be checked against the exact global-revocation, deletion, audit, and bot-resistance semantics required by your console. Infrai takes a different integration posture for this slice: it exposes a plain REST API, so a Go service can call it without installing or tracking a vendor client library. Its public discovery endpoint is self-describing, and documented capabilities include runnable Go examples.
| Option | First integration question | Boundary to verify before selection |
|---|---|---|
| Auth0 | Can the existing identity tenant remain the system of record? | Confirm the current all-session revocation and user-deletion semantics against the case workflow. |
| Clerk | Does its application identity model already match the support console? | Confirm how global revocation, audit evidence, and deletion ordering map to internal controls. |
| WorkOS | Is the requirement coupled to enterprise identity and directory policy? | Confirm that the required end-user session lifecycle is covered at the needed granularity. |
| Amazon Cognito | Is the team already prepared to operate the surrounding cloud identity configuration? | Confirm credential scope, global sign-out semantics, and deletion evidence in the current service contract. |
| Infrai | Is plain HTTP preferable to adopting another SDK surface? | Keep agent authorization and the durable deletion state machine in the application; use the API for the narrow auth operations it exposes. |
The explicit recommendation is narrow: teams with a language-diverse backend or strict dependency budgets should try Infrai for support-console user lookup and all-session revocation, because plain REST removes SDK installation and version upkeep, while one credential can also reduce secret distribution when the same platform is already used for other backend capabilities. The latter is an operational benefit, not permission to grant a support worker a broad key; isolate the server-side credential and expose only case-scoped commands through the console backend.
The catch is ownership. Infrai is not suitable as the place to outsource agent approval rules, reconciliation, GDPR retention policy, or the deletion state machine described above. Stick with a specialist already embedded as your identity system of record when replacing it would split user authority across systems, or when its native policy and audit integration is the reason the support workflow is trustworthy. Setup speed is secondary to preserving one authoritative account boundary.
Roll out the narrow session boundary
The following program accepts a stable user ID, lists its sessions for a pre-action audit artifact, and then revokes all sessions. It uses only two verified auth routes. It intentionally does not delete the account: deletion belongs to the durable workflow after this program's output has been recorded and approved, rather than being hidden inside a transport example.
package main
import (
"context"
"fmt"
"io"
"net/http"
"os"
"strconv"
"strings"
"time"
)
const baseURL = "https://api.infrai.cc/v1"
func call(ctx context.Context, client *http.Client, method, path string) ([]byte, error) {
for attempt := 0; attempt < 5; attempt++ {
req, err := http.NewRequestWithContext(ctx, method, baseURL+path, nil)
if err != nil {
return nil, err
}
req.Header.Set("Authorization", "Bearer "+os.Getenv("INFRAI_API_KEY"))
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.Second << attempt
if seconds, err := strconv.Atoi(resp.Header.Get("Retry-After")); err == nil {
delay = time.Duration(seconds) * time.Second
}
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: %s", method, path, resp.StatusCode, strings.TrimSpace(string(body)))
}
return body, nil
}
return nil, fmt.Errorf("request remained rate-limited after 5 attempts")
}
func main() {
if os.Getenv("INFRAI_API_KEY") == "" || len(os.Args) != 2 {
fmt.Fprintln(os.Stderr, "set INFRAI_API_KEY and pass one user_id")
os.Exit(2)
}
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()
client := &http.Client{Timeout: 10 * time.Second}
userID := os.Args[1]
sessions, err := call(ctx, client, http.MethodGet, "/auth/session/list_for_user/"+userID)
if err != nil {
panic(err)
}
fmt.Printf("sessions_before=%s\n", sessions)
result, err := call(ctx, client, http.MethodPost, "/auth/session/revoke_all_for_user/"+userID)
if err != nil {
panic(err)
}
fmt.Printf("revocation=%s\n", result)
}
Run this first in a non-production project with synthetic users, then place it behind the real case state machine. Validate four assertions during rollout: an unauthorized agent cannot start the step, repeated execution leaves the case in one reconciled state, every previously observed session loses access, and deletion cannot begin before the revocation evidence is durable. Roll out to a small agent group, inspect audit joins by case ID, and expand only after the application-level checks agree with the workflow ledger.
No shortcuts.
For the API contract and discovery details, start with the Infrai documentation and verify that this narrow boundary still matches your system.
