What reusable identity unlocks
Every Didit KYC ships a signed Reusable Identity credential to the user's wallet. Every receiving platform validates it for free with selective disclosure. One verification, every business that accepts Didit. 500 verifications free every month.
Pick the checks you want, ID, liveness, face match, sanctions, address, age, phone, email, custom questions. Drag them into a flow in the dashboard, or post the same flow to our API. Branch on conditions, run A/B tests, no code required.
Embed natively with our Web, iOS, Android, React Native, or Flutter SDK. Redirect to a hosted page. Or just send your user a link, by email, SMS, WhatsApp, anywhere. Pick what fits your stack.
Didit hosts the camera, the lighting cues, the mobile hand-off, and accessibility. While the user is in the flow, we score 200+ fraud signals in real time and verify every field against authoritative data sources. Result in under two seconds.
Real-time signed webhooks keep your database in sync the moment a user is approved, declined, or sent to review. Poll the API on demand. Or open the console to inspect every session, every signal, and manage cases your way.

# Returns disclosed fields + issuer chain
# when reusable_identity.presented is true.
# Returns the full KYC evidence pack
# when a fresh KYC was run.You are integrating Didit's Reusable Identity / eIDAS 2.0 acceptance into your platform. Two flows:
1. Issue — when a new user runs a full KYC on your platform, they leave with a Didit-signed Reusable Identity credential in their wallet (the Didit app or any EU Digital Identity Wallet).
2. Accept — when a user arrives at your platform already holding a Didit-signed credential, the session detects it and short-circuits, returning Approved without re-running the full KYC.
Bundle pricing (verified live 2026-05-16):
- First verification (issuance side): $0.33 per user (Sessions API full KYC bundle)
- Issuance: free — the signed credential is included with every KYC
- Reuse on the verifying side: free, forever
- Selective disclosure: free
- Continuous Anti-Money Laundering (AML) refresh: $0.07 per user per year (automatic)
- First 500 verifications free every month, forever
PRE-REQUISITES
- Production API key from https://business.didit.me (sandbox key in 60 seconds, no credit card).
- Webhook endpoint with HMAC SHA-256 verification of the X-Signature-V2 header.
HMAC-SHA256 verification MUST run against the raw body bytes (the raw payload as Didit sent it) BEFORE any JSON parsing — re-serialising the parsed body changes whitespace and key order, which invalidates the signature. - A workflow_id from the no-code Workflow Builder with:
* ID Verification + Passive Liveness + Face Match 1:1 + Device & IP Analysis + AML Screening (for issuance)
* Reusable Identity acceptance turned on (for acceptance — toggle in the Workflow Builder)
- Optional: the Didit mobile SDK (iOS / Android / React Native / Flutter) for native deep-link wallet handoff.
STEP 1 — Open a session that accepts a Reusable Identity if presented
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<wf id with Reusable Identity acceptance on>",
"vendor_data": "<your user id>",
"callback": "https://<your-app>/onboarding/callback",
"metadata": {
"purpose": "platform_onboarding",
"request_fields": ["full_name", "age_over_18", "country_of_residence"]
}
}
Optional in body: declare the exact fields you need disclosed via metadata.request_fields. Didit's hosted flow will prompt the user to approve only those specific fields when they present a Reusable Identity credential.
Response: 201 Created with the hosted session URL. Redirect the user.
STEP 2 — The hosted flow detects (or runs) the verification
Two paths from this one endpoint:
Path A — User has a Didit-signed credential
- The hosted flow detects the credential via a wallet-handoff prompt (universal link on mobile, popup-bridge on desktop)
- The user approves the disclosure of the requested fields
- Didit validates the issuer signature + credential freshness server-side
- Session returns Approved with the disclosed fields populated on the decision payload
- Cost: $0 on the verifying side
Path B — User does NOT have a credential
- The hosted flow runs the full KYC bundle (ID + Liveness + Face Match + Device & IP + AML)
- At completion, Didit issues a Reusable Identity credential to the user's wallet
- Session returns Approved with the full decision payload
- Cost: $0.33 on the verifying-and-issuing side
Same endpoint, same webhook, same status enum. The path is transparent to your back-end.
STEP 3 — Read the signed webhook
Didit POSTs to your callback. Session statuses (Title Case With Spaces):
Body (excerpted):
{
"session_id": "<uuid>",
"vendor_data": "<your user id>",
"status": "Approved",
"id_verification": { "status": "Approved" },
"liveness": { "status": "Approved" },
"face": { "status": "Approved", "similarity_score": 0.94 },
"ip_analysis": { "status": "Approved" },
"aml": { "status": "Approved", "hits": [] },
"reusable_identity": {
"presented": true,
"issuer": "<issuing-platform name>",
"issued_at": "<timestamp>",
"disclosed_fields": ["full_name", "age_over_18", "country_of_residence"]
}
}
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.
When reusable_identity.presented is true, the user re-presented an existing credential and the verification was free; when false, a fresh KYC was run and billed at $0.33.
STEP 4 — Retrieve the full decision later
GET https://verification.didit.me/v3/session/{sessionId}/decision/
Headers:
x-api-key: <your api key>
Returns the full payload including: document scan + extracted Machine-Readable Zone (MRZ) data, biometric similarity, AML hits, device + IP risk signals, 200+ fraud signals, HMAC signature, and (if presented) the credential issuance chain.
Same evidence pack regardless of issuance vs reuse — the verifier never sees less than a fresh KYC would deliver.
STEP 5 — Continuous AML monitoring is automatic
Every approved user (issued OR presented) is re-screened daily against 1,300+ sanctions, PEP, and adverse-media lists at $0.07 per user per year on heavy-volume accounts. When a previously-clean user crosses an AML threshold, the credential's AML field is updated automatically; every receiving platform sees the refreshed status on next presentation.
When the user revokes a credential from their wallet, your receiving platform's webhook fires with status: Expired and the credential is dropped from the user's account.
STEP 6 — Selective disclosure at presentation time
Pass the exact fields you need via metadata.request_fields at session creation. Recommended minimum-disclosure patterns:
- Age-gate (UK Online Safety Act, France SREN): ["age_over_18"]
- Country-gate: ["country_of_residence"]
- Full name + verified-human: ["full_name", "verified_human"]
- AML-clear gate (lending): ["aml_clear", "full_name"]
- Full identity (banking, payments): ["full_name", "date_of_birth", "address", "document_number", "aml_clear"]
The user sees a single approval prompt listing the requested fields. Anything not listed is never disclosed to your platform.
WEBHOOK EVENT NAMES
- Sessions: status changes flow through the standard session webhook (verify X-Signature-V2 HMAC SHA-256).
- Credential lifecycle: status: Expired fires when a holder revokes the credential.
CONSTRAINTS
- Session statuses use Title Case With Spaces. Don't UPPER_SNAKE_CASE them.
- Reusable Identity acceptance is OFF by default; turn it on in the Workflow Builder.
- Selective disclosure is the privacy default — fields not in metadata.request_fields are never returned, even if the credential carries them.
- Default record retention is 5 years post-relationship per the EU AML package.
- 200+ fraud signals are evaluated on every session, issued or presented, at no extra cost.

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.
eIDAS 2.0, short for electronic IDentification, Authentication and trust Services, is the EU's 2024 update to its identity rulebook. The headline change is the European Digital Identity Wallet (often shortened to EUDI Wallet): a smartphone app every EU citizen and resident will be entitled to by the end of 2026.
The wallet holds verifiable credentials, a digital driving licence, a verified-identity attestation, an academic diploma, issued by trusted parties and presented to relying parties with cryptographic proof, optionally with selective disclosure (prove you are over 18 without revealing your full date of birth).
For businesses, eIDAS 2.0 is about both accepting wallet-presented credentials and issuing the credentials your users carry.
Mandatory acceptance is rolling in by sector:
Outside the mandatory list, every EU business has the option to issue and accept wallet credentials voluntarily, and most regulated businesses will, because the user experience is dramatically better than re-running a full KYC.
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.
Federated login proves an account exists with the identity provider, the receiving business gets an email address and maybe a name. That is not regulatory-grade identity.
Reusable identity carries:
The verifier gets the same regulatory comfort it would get from running its own KYC, without the cost, the friction, and the conversion drop.
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:

Reusable identity is a privacy upgrade on the legacy KYC stack:
The legal basis for processing on the receiving side is legitimate interest under GDPR, the user has explicitly presented a credential to access the service. Didit's standard Data Processing Agreement (DPA) covers the joint-controller relationship.
Three trigger types:
The receiving platform never has to chase the user for updates, the credential carries its own freshness signal, and stale credentials are rejected at presentation time.
The verifier (the receiving platform) gets the same per-presentation evidence pack the original verifier got, plus the chain of issuance:
Didit is the only KYC provider with a formal EU member-state government attestation, Spain's Treasury, Banco de España, and SEPBLAC jointly attested the service as safer than in-person verification. That attestation extends to every reused presentation.
