Satu alur kerja Didit menangani identitas pembeli dan dompet tujuan, sebelum kripto berpindah tangan. Gratis 500 verifikasi setiap bulan.
Robinhood Ventures
Dipercaya oleh 2.000+ organisasi di seluruh dunia.
Kewajiban on-ramp
Setiap on-ramp yang teregulasi wajib melakukan dua hal, KYC pada pembeli + KYT pada dompet tujuan, untuk setiap pembelian. Didit menyediakannya dalam satu alur kerja: $0.33 KYC + $0.17 transaksi (termasuk penyaringan dompet terkelola) = $0.50 per pembelian. BYOK pada penyedia dompet menurunkannya menjadi $0.37. Gratis 500 verifikasi setiap bulan.
Pilih pemeriksaan yang Anda inginkan, ID, liveness, face match, sanksi, alamat, usia, telepon, email, pertanyaan kustom. Seret ke dalam alur di dashboard, atau kirim alur yang sama ke API kami. Buat cabang berdasarkan kondisi, jalankan A/B test, tanpa perlu coding.
Integrasikan secara native dengan SDK Web, iOS, Android, React Native, atau Flutter kami. Redirect ke halaman yang di-host. Atau cukup kirim tautan kepada pengguna Anda, via email, SMS, WhatsApp, di mana saja. Pilih yang sesuai dengan stack Anda.
Didit mengelola kamera, isyarat pencahayaan, hand-off seluler, dan aksesibilitas. Saat pengguna dalam alur, kami menilai 200+ sinyal fraud secara real-time dan memverifikasi setiap bidang terhadap sumber data otoritatif. Hasil dalam waktu kurang dari dua detik.
Webhook bertanda tangan real-time menjaga database Anda tetap sinkron saat pengguna disetujui, ditolak, atau dikirim untuk ditinjau. Lakukan polling API sesuai permintaan. Atau buka konsol untuk memeriksa setiap sesi, setiap sinyal, dan mengelola kasus sesuai keinginan Anda.

}'{ status APPROVED · IN_REVIEW · DECLINED · AWAITING_USER }You are integrating Didit into a fiat-to-crypto on-ramp. Two obligations on every buy:
1. Verify the buyer (KYC) — identity, liveness, face match, device + IP, AML against 1,300+ sanctions / PEP / adverse-media lists. ONE call to the Sessions API.
2. Screen the destination wallet (KYT) — risk-score the address against sanctioned wallets, mixers, high-risk counterparties BEFORE the crypto leaves. ONE call to the Transactions API with currency_kind: "crypto".
Bundle pricing (verified live against POST /v3/transactions/, 2026-05-16):
- KYC bundle: $0.33 per buyer (Sessions API)
- Transactions API call: $0.02 base (transaction-monitoring) + $0.15 wallet screening (Didit's default managed provider) = $0.17 per buy
- Total managed: $0.33 + $0.17 = $0.50 per fully-screened buy
- Total with BYOK on the wallet provider: $0.33 + $0.04 = $0.37 per buy
- First 500 KYC verifications free every month, forever
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 bundles ID Verification + Passive Liveness + Face Match 1:1 + Device & IP Analysis + AML Screening.
- Transaction Monitoring enabled in the Business Console (Transactions > Settings) with crypto screening turned on.
STEP 1 — Verify the buyer with the Sessions API
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<wf id with KYC + AML modules>",
"vendor_data": "<your buyer id, max 256 chars>",
"callback": "https://<your-app>/onramp/kyc/callback",
"metadata": {
"purpose": "crypto_onramp_buy",
"buy_id": "<your internal tx reference>"
}
}
Response: 201 Created with the hosted session URL. Redirect the buyer to it. Sub-2-second median verdict on completion.
STEP 2 — Read the signed webhook on KYC completion
Didit POSTs to your callback. Session statuses are Title Case With Spaces:
Body (excerpted):
{
"session_id": "<uuid>",
"vendor_data": "<your buyer 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": [] }
}
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 — Screen the destination wallet BEFORE crediting the buy
POST https://verification.didit.me/v3/transactions/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body (required fields verified live 2026-05-16):
{
"transaction_id": "<your internal buy reference>",
"transaction_category": "finance",
"include_crypto_screening": true,
"transaction_details": {
"direction": "OUTBOUND",
"amount": "0.25",
"currency": "ETH",
"currency_kind": "crypto",
"action_type": "withdrawal"
},
"subject": {
"entity_type": "individual",
"vendor_data": "<your buyer id>",
"full_name": "<buyer full name>"
},
"counterparty": {
"entity_type": "unhosted_wallet",
"full_name": "<destination wallet label>",
"payment_method": {
"method_type": "crypto_wallet",
"account_id": "<destination wallet address>"
}
}
}
REQUIRED fields the API rejects if missing:
- subject.vendor_data + subject.full_name
- counterparty.full_name
- transaction_details.direction + currency + currency_kind + amount
- For crypto: a wallet address on counterparty.payment_method.account_id (OUTBOUND) or subject.payment_method.account_id (INBOUND post-transfer)
Wallet screening runs server-side when currency_kind = "crypto" and there is a wallet address in the right participant. No separate endpoint.
Response shape (excerpted from a real successful 201):
{
"uuid": "<server transaction uuid>",
"txn_id": "<your transaction_id echoed back>",
"status": "APPROVED",
"score": 0,
"severity": null, // null when score is 0; LOW | MEDIUM | HIGH | CRITICAL | UNKNOWN otherwise
"props": {
"wallet_risk_score": 0,
"sanctions_hit": false,
"pep_counterparty": false,
"aml_provider": "<provider slug>", // identifies the screening provider used on this call
"aml_screening_type": "WALLET_SCREENING",
"aml_screening_status": "COMPLETED"
},
"provider_results": [{ "provider": "<provider slug>", "result_type": "WALLET_SCREENING", "status": "SCREENED", ... }],
"cost_breakdown": {
"total_price": 0.17,
"items": [
{ "usage_type": "transaction_aml_monitoring", "price": 0.15 },
{ "usage_type": "transaction_monitoring", "price": 0.02 }
]
}
}
Transaction status enum (exact case, UPPER_SNAKE_CASE): APPROVED | IN_REVIEW | DECLINED | AWAITING_USER.
When a transaction enters AWAITING_USER, Didit creates a linked remediation session automatically and returns a verification URL on the response.
Real per-transaction cost (verified live):
- Plain fiat transaction monitoring: $0.02
- Crypto transaction with managed wallet screening: $0.17 ($0.02 TM base + $0.15 wallet screen on Didit's managed flow)
- Crypto transaction with BYOK wallet screening: $0.04 ($0.02 TM base + $0.02 wallet screen)
Branch logic:
APPROVED → send the crypto.
IN_REVIEW → hold the buy, route to analyst queue.
DECLINED → refund the fiat, block the address.
AWAITING_USER → redirect the buyer to the remediation session URL.
STEP 4 — Ongoing AML monitoring is automatic
Any session with AML enabled is rescreened DAILY by Didit's continuous monitoring at $0.07 per user per year. There is NO separate endpoint to call — the same workflow does it.
When a previously-approved buyer crosses an AML threshold, the session status changes to "In Review" or "Declined" automatically and your webhook fires the update.
STEP 5 — Off-ramp uses the same two endpoints
Selling crypto for fiat:
- KYC the seller via POST /v3/session/ (same as Step 1).
- Screen the source wallet via POST /v3/transactions/ with direction: "INBOUND" and the source wallet address on subject.payment_method.account_id.
WEBHOOK EVENT NAMES
- Sessions: status changes flow through the standard session webhook.
- Transactions: transaction.created · transaction.updated · transaction.status.changed · transaction.alert.generated.
Verify X-Signature-V2 on every payload.
CONSTRAINTS
- Session statuses use Title Case With Spaces (Approved, In Review). Transaction statuses use UPPER_SNAKE_CASE (APPROVED, IN_REVIEW). They live in different APIs — don't mix them in the same code path.
- Wallet Screening MUST run BEFORE the crypto leaves — a post-transfer screen is useful for audit but useless for blocking.
- Default record retention is 5 years post-relationship per the EU AML package; extend per your supervisor's guidance.
- 200+ fraud signals are evaluated on every KYC session at no extra cost — surface the score via the session decision payload, don't re-query.

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.
An on-ramp is the service that lets someone pay with a card or bank transfer and receive crypto in their wallet. Think MoonPay, Ramp, Transak, and Didit customers like AhoraCrypto and GBTC Finance.
Two things can go wrong on every buy, so you need two checks:
A clean buyer can still send funds to a bad wallet, and a clean wallet can still be funded by a bad buyer. Both checks, every buy. Didit ships them as one workflow for $0.50 per buy ($0.33 KYC + $0.17 transaction with managed wallet screening), or $0.37 when you bring your own wallet-screening key.
KYC is about the person: name, document, face, sanctions, where they're logging in from. You run it once at signup and refresh it later.
KYT is about the wallet: where it sits in the on-chain graph, who it's transacted with, whether it's been flagged. You run it on every transaction.
A regulated on-ramp owes both. Didit gives you one workflow that runs the KYC on the buyer and the KYT on the destination wallet in the same flow, no extra moving parts.
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.
Same two checks, reverse direction:
One workflow handles buy and sell. One contract, one invoice, one audit trail for both directions.
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:
Detailed memo, every certificate, every regulator letter: /security-compliance.
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.
Yes. The EU Travel Rule (the Transfer of Funds Regulation) says CASPs must exchange originator and beneficiary data on every crypto transfer, no minimum threshold for crypto in the EU.
Didit handles it with:
One workflow, both halves, KYC on the user, Travel Rule data on the transfer.
Didit re-checks every approved buyer daily against the same 1,300+ lists used at signup. It's automatic, there's no separate endpoint to call, no extra setup, no extra cost on most plans (and $0.07 per user per year on heavy-volume accounts).
When a previously-clean buyer crosses an AML threshold:
In Review or Declined automaticallyFor a million-buyer base that's single-digit dollars per buyer per year, orders of magnitude cheaper than a manual review queue.
Sandbox in 5 minutes. Production in a weekend.
POST /v3/session/) and one into your buy step (POST /v3/transactions/)If you'd rather have an AI agent build it (Claude Code, Cursor, Codex, Devin, Aider, Replit Agent), paste the integration prompt from the section above and the agent scaffolds the flow. Native SDKs for Web, iOS, Android, React Native, and Flutter all share the same session model.
