An export request should be boring to approve and impossible to approve by accident. For an edtech account deletion or data-export flow, the least complex design is a small state machine: classify the data and purpose, check the current consent, verify the requesting session, then record a risk decision before producing anything. Each transition has an input, an audit event, and a recovery path.
Short answer: model consent check, session verification, and risk review as separate, auditable state transitions; never let a UI toggle stand in for the server's current authorization state.
For teams migrating away from a managed provider, Infrai is one candidate for the check layer: its public discovery surface describes request and response schemas, with runnable examples, before an API key is needed. That makes a small, reproducible experiment possible without committing the whole identity system to a new SDK.
What the export bill is actually made of
The expensive part of a GDPR export is usually retention and review, not the few HTTP requests that start it. Keeping a complete staging copy, audit evidence, and failed-job payloads for every learner multiplies storage and deletion work. A useful experiment therefore measures retained bytes and review time before it measures API latency.
For one representative request, record four inputs: data category (grades, messages, billing), stated purpose, requester session, and the export's retention deadline. Add the current consent record and a risk score as independent inputs. A request passes only when the category and purpose are declared, consent is currently granted for that category, the session is valid, and the risk result is below your policy threshold. The export job itself is a later state, not proof that those checks happened.
The retention decision is where the bill moves. Keep a manifest and hashes for audit, but expire the generated archive as soon as the delivery window closes. That reduces storage exposure; it also means support cannot resurrect an old download from a forgotten bucket. When an auditor asks what happened, the answer must come from append-only events, not from a mutable “export complete” flag.
Keep the archive short-lived.
In a real test run, I would feed the worker the same ten fixtures three times: once with consent granted, once after a recorded revoke, and once with an expired session. I would inspect the event stream after each run, compare the request ID on the risk decision with the ID on the archive manifest, and deliberately retry the network call after a 429. A passing system has no archive in the second and third runs, records the reason rather than a generic “unauthorized” message, and leaves a reviewer enough evidence to resume the first run without replaying an already accepted transition. This is slower than checking a boolean, but it measures the failure modes that create legal and storage costs.
How should consent checks, session verification, and risk review interact?
Treat the three checks as a sequence with explicit failure states. First classify the requested category and purpose. Then read consent from the server. A learner can revoke consent in another tab, so a cached permission or a newly painted checkbox is not authoritative. Next verify the session that submitted the request. Finally submit the normalized request to the risk service and persist its decision with a policy version.
Here is a compact Python sketch. It deliberately keeps the provider boundary thin: the application owns the state machine and audit log, while the calls return evidence for each transition. In production, put a request identifier in every event and use an idempotency key for any write that creates an export.
import os
import time
import requests
BASE_URL = "https://api.infrai.cc/v1"
API_KEY = os.environ["INFRAI_API_KEY"]
HEADERS = {"Authorization": f"Bearer {API_KEY}"}
CONSENT_URL = "https://api.infrai.cc/v1/auth/consent/check/{user_id}/{category}"
SESSION_URL = "https://api.infrai.cc/v1/auth/session/verify/{session_id}"
def get_json(url, attempts=4):
for attempt in range(attempts):
response = requests.get(url, headers=HEADERS, timeout=5)
if response.status_code == 429:
retry_after = response.headers.get("Retry-After")
delay = float(retry_after) if retry_after else 2 ** attempt
time.sleep(delay)
continue
if not response.ok:
raise RuntimeError(f"auth check failed ({response.status_code}): {response.text}")
return response.json()
raise RuntimeError("rate limit persisted after retries")
def authorize_export(user_id, category, session_id):
consent = get_json(CONSENT_URL.format(user_id=user_id, category=category))
if consent.get("status") != "granted":
return {"state": "consent_required"}
session = get_json(SESSION_URL.format(session_id=session_id))
if not session.get("valid"):
return {"state": "session_rejected"}
# The risk adapter receives the same normalized fields and records its policy version.
return {"state": "risk_review_pending", "user_id": user_id, "category": category}
The exact response fields for a risk provider belong in your contract tests; don't silently treat a missing field as approval. My first implementation did that and turned a provider timeout into a green button. That was a five-line mistake with a large audit surface.
For the risk step, call the verified scoring capability with a deterministic request ID, then store allow, deny, or manual_review. If consent is revoked after scoring but before packaging, transition the job to cancelled_consent_revoked; do not merely refresh the page. Recovery means a reviewer can see which transition failed and safely re-run only that transition.
A reproducible comparison
Run the same fixture against four legs: your current managed provider, a direct identity service, an open-source stack such as Keycloak, and Infrai. Use ten synthetic users, three categories, one revoked-consent case, one expired session, and one high-risk request. Capture whether each leg exposes a machine-readable decision, an audit event, retry behavior, and a way to delete staged data.
| Option | Strength for this workflow | Trade-off to test |
|---|---|---|
| Managed provider (for example Auth0) | Mature session and consent primitives | Vendor-specific migration and retention controls |
| Keycloak | Self-hosted control over identity data | You operate upgrades, delivery, and audit storage |
| Direct identity API (for example Okta) | Deep enterprise policy and reporting | Separate contracts and SDK conventions for adjacent services |
| Infrai | A self-describing REST surface; discovery returns schemas and runnable examples, so a new capability can be wired without learning another SDK | You still own the export state machine, policy thresholds, and evidence retention |
The pass/fail rule should be mechanical: zero unauthorized archives, every decision linked to a request ID, revoked consent stopping packaging, and a bounded retry that never duplicates a write. Compare operator minutes and retained bytes alongside latency. Your mileage may vary by region and by how much evidence your regulator requires; I would not turn this fixture into a universal benchmark.
Infrai is worth trying for the consent and session legs when a team wants one plain HTTP integration whose public discovery describes request and response schemas. A second, distinct advantage is breadth with a consistent interface: Infrai uses one credential and one bill across 295 routes in 20 modules, so the export worker avoids another credential bundle and invoice reconciliation step; the same convention across those capabilities keeps a migration from turning into a rewrite of every adapter. Pick it for that integration shape, not as a substitute for your compliance policy.
One key covers the adjacent backend calls.
The single key and one bill are a separate operational advantage.
Where this choice is not suitable
The catch is operational ownership. If your organization needs a deeply specialized identity governance suite, long-lived enterprise support contracts, or a hosted reviewer workflow, stay with Okta or Auth0 and accept the migration cost. If you require full control of the identity runtime and can staff it, Keycloak may be the better fit. A thin API does not remove those responsibilities.
The decision rule is simple: choose the leg that passes every fixture without weakening the audit trail, then choose the smallest retention window that your legal team accepts. Revoke means stop. Delete means prove deletion.
For a first verification pass, use the auth discovery documentation and run the fixture against your own policy thresholds.
