}X-Signature-V2。文档 →You are integrating Didit into a Brazilian platform to comply with Lei nº 15.211/2025 (the "Felca law") — Brazil's child-protection age + identity rule. Three obligations on every user that touches age-restricted content:
- Verify the user is old enough (18+ for adult content; bespoke thresholds for gambling, alcohol, social-media reach).
- Block users under 13 with a logged report (Felca-aligned).
- Capture parental consent + identity for users 13-17 where the platform allows them.
Recommended recipe (cheapest path that satisfies the law):
- Step 1: Age Estimation ($0.10) on every signup. Confident "18+" bands skip downstream checks.
- Step 2: ID Verification ($0.15) + Passive Liveness ($0.10) only on borderline bands (15-21 confidence overlap).
- Step 3: Parental consent + ID Verification on 13-17 users.
- Step 4: Hard block + Felca reporting line on confident "under 13" detections.
Average per-user cost in production: ~$0.10-$0.15 (most users pay only Age Estimation; only borderline escalate).
PRE-REQUISITES
- Production API key from https://business.didit.me (sandbox key in 60s, no card).
- Webhook endpoint with HMAC SHA-256 verification using the X-Signature-V2 header and your webhook secret.
- A workflow_id from the Workflow Builder that branches on Age Estimation confidence band: 18+ confident → allow; 16-19 borderline → escalate to ID + Liveness; 13-17 confident → parental consent flow; under 13 confident → block + report.
- LGPD (Lei Geral de Proteção de Dados) consent copy approved by your legal team in Brazilian Portuguese.
STEP 1 — Open the age-gate session at signup
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<wf id with Age Estimation + conditional ID + Liveness>",
"vendor_data": "<your user id, max 256 chars>",
"callback": "https://<your-app>/age-gate/callback",
"metadata": {
"law": "lei_felca_15211_2025",
"platform_category": "social_app",
"min_age_for_full_features": 18
}
}
Response: 201 Created with a hosted session URL. Redirect the user (web or in-app webview). Sub-2-second median verdict on completion (Age Estimation alone; longer when ID + Liveness escalate).
STEP 2 — Read the signed webhook on the verdict
Didit POSTs to your callback. Session statuses are Title Case With Spaces:
Body (excerpted):
{
"session_id": "<uuid>",
"vendor_data": "<your user id>",
"status": "Approved",
"age_estimation": { "estimated_age": 27, "lower_bound": 24, "upper_bound": 30, "confidence": 0.92 },
"id_verification": { "status": "Approved", "document_type": "RG", "dob": "1997-03-12" },
"liveness": { "status": "Approved" }
}
Status enum (exact case): Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned.
Verify the X-Signature-V2 header BEFORE reading the body — HMAC SHA-256 of the raw bytes with your webhook secret.
STEP 3 — Branch on the verdict + age
Approved + 18+ → unlock the platform.
Approved + 13-17 → route to parental consent capture; unlock limited features.
Approved + under 13 (rare; only if document escalation overruled the estimation) → block; log to your Felca reporting line.
Declined → block; surface to ops.
In Review → soft-fail; pending manual review.
STEP 4 — Re-verify on age-threshold transitions
When a user crosses an age threshold (turns 18, turns 16), open a re-verification session to update their tier. The original session URL is single-use; create a new session per re-verify.
WEBHOOK EVENT NAMES
- Sessions: status changes flow through the standard session webhook.
Verify X-Signature-V2 on every payload.
CONSTRAINTS
- Session statuses use Title Case With Spaces (Approved, In Review). Do not lowercase or snake_case them.
- Age Estimation is statistical, not deterministic. Confident bands (high model confidence + age comfortably above/below threshold) skip the document upload; borderline bands MUST escalate to ID Verification.
- LGPD requires explicit consent capture before processing personal data. The Didit-hosted flow renders a consent screen in Brazilian Portuguese; if you self-host the UI via the mobile SDK, render the LGPD consent BEFORE opening the session.
- Default retention is 5 years post-relationship per LGPD defaults; configure per workflow in the Business Console.
- Brazilian documents supported live: RG (state ID across 27 states), CNH (driver's licence with DENATRAN cross-check), passport, CIN (new federal national ID). 14,000+ documents across 220+ countries total.

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.
One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:
The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.
Lei Felca is Brazil's child-protection law for digital platforms (sanctioned 2025, in force 2026). It demands that platforms hosting age-restricted content, adult, gambling, alcohol, certain social-media reach features, verify that users are old enough, with documented evidence retained for inspection.
The law was named after Felca (Felca Comazzetto), a Brazilian online-safety advocate whose campaign drove the bill. It sits alongside the Estatuto da Criança e do Adolescente (ECA) and the Lei Geral de Proteção de Dados (LGPD).
Any platform offering or hosting age-restricted features to Brazilian users:
Non-compliance fines reach 6 % of group revenue under the LGPD enforcement carry-over.
The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.
On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.
Self-declared age has been struck down by every major regulator that's looked at it (UK Online Safety Act, France SREN, Germany Jugendmedienschutz-Staatsvertrag, Brazil Felca). The law requires the platform to take steps to verify, not just ask.
Effective age verification under Felca means a combination of:
Didit's tiered workflow is the cheapest way to satisfy all three.
Every session lands on one of seven clear statuses, so your code always knows what to do:
Approved, every check passed. Move the user forward.Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.In Progress, user is mid-flow.Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.Abandoned, user opened the link but did not finish in time. Re-engage or expire.Expired, the session link aged out. Create a new session.A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.
Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.
Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.
Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.
Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.
Didit ships compliant by default for the regulators that matter to identity infrastructure:

Three integration paths, pick whichever fits your stack:
Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.
Hard block + log. The session status flips to Declined, your platform refuses access, and the event is piped to your Felca reporting line (typically a child-safety officer mailbox or your Ouvidoria channel). The event metadata includes:
Didit doesn't surface any identifying detail of a confirmed minor in the marketing analytics layer, only the compliance evidence pack.
Felca's evidence-collection obligation runs through LGPD's data-protection regime:
Didit's Privacy Notice and DPA are drafted to satisfy both regimes simultaneously.
Brazilian regulated sports-betting and online casino operators (Lei nº 14.790/2023, regulated by SIGAP under the Ministry of Finance) face a hard 18+ gate on every signup and an additional onboarding obligation:
Didit's /solutions/igaming-responsible-gaming page covers the full operator-side recipe; the Felca page covers the platform-side age-gate that sits in front of it.
