Quickstart
Create an API key and submit your first KYC request in three minutes.
This is the fastest path from "I have a Certivant account" to "a verification request is in flight." If you finish this page, you have a working integration end-to-end.
What you need
- A Certivant organization (sign up at your tenant URL — the trial includes free credits).
- The role Owner or Admin on that organization. Members cannot mint API keys.
- A way to make HTTPS requests —
curl, Postman, or your language's HTTP client.
1 — Create an API key
Click New Key, give it a label, choose Live or Test (for example a label such as staging-server), and pick the scopes you need:
kyc:read— read requests, documents, fraud signalskyc:write— create requests, upload documentskyc:submit— submit a request for automated processingkyc:manage— override decisions, delete applicants (GDPR)
ck_live_ (or ck_test_ if you chose the test environment). Copy it now — Certivant only stores a hash, so you cannot recover it later. If you lose it, revoke the key and create a new one.Treat API keys like passwords. Store them in your secrets manager, never commit them to git, and use a separate key per environment (staging vs. production). Revoke a key the moment you suspect exposure.
2 — Create a KYC request
The minimum payload only needs a type. Add applicant data inline if you have it — otherwise the applicant fills it in via a hosted session. The same end-to-end flow (create -> upload documents -> submit -> poll) in eight languages:
# 1. Create a verification request
curl -X POST https://app.certivant.com/api/v1/kyc/requests \
-H "Authorization: Bearer ck_live_your_key_here" \
-H "Content-Type: application/json" \
-d '{
"type": "INDIVIDUAL",
"externalRef": "user_123",
"applicant": {
"fullName": "Jane Doe", "email": "jane@example.com", "nationality": "US",
"emailVerified": false, "phoneVerified": false
}
}'
# -> { "id": "req_...", "status": "PENDING_UPLOAD", ... }
# 2 & 3. Upload an identity document (front) + a selfie
curl -X POST https://app.certivant.com/api/v1/kyc/requests/{requestId}/documents \
-H "Authorization: Bearer ck_live_your_key_here" \
-F "file=@passport.jpg" -F "documentType=PASSPORT" -F "side=front"
curl -X POST https://app.certivant.com/api/v1/kyc/requests/{requestId}/documents \
-H "Authorization: Bearer ck_live_your_key_here" \
-F "file=@selfie.jpg" -F "documentType=SELFIE"
# 4. Submit for AI processing (email + phone must already be verified if your org requires it)
curl -X POST https://app.certivant.com/api/v1/kyc/requests/{requestId}/submit \
-H "Authorization: Bearer ck_live_your_key_here"
# 5. Poll for the decision (or just listen for the webhook)
curl https://app.certivant.com/api/v1/kyc/requests/{requestId} \
-H "Authorization: Bearer ck_live_your_key_here"

A successful response looks like:
{
"id": "req_01HXY...",
"status": "PENDING_UPLOAD",
"type": "INDIVIDUAL",
"externalRef": "order-12345",
"pendingDocTypes": ["GOVERNMENT_ID", "SELFIE"],
"applicant": { "fullName": "Jane Doe", "email": "jane@example.com" },
"createdAt": "2026-05-27T10:00:00.000Z"
}
Save the id — every subsequent call needs it.
The externalRef field is your foreign key. Use your order ID,
your user ID, anything that lets you correlate the Certivant
request back to a row in your own database. It's returned on every
webhook event.
3 — Get the applicant a hosted session
The easiest way to collect documents is to send the applicant a short-lived URL. Certivant handles document capture, liveness, and the upload UI; you just hand them the link.
curl -X POST https://app.certivant.com/api/v1/kyc/requests/req_01HXY.../session-url \
-H "Authorization: Bearer ck_live_your_key_here" \
-H "Content-Type: application/json" \
-d '{
"expiresInHours": 72,
"redirectUrl": "https://yourapp.example.com/onboarding/complete"
}'
Returns:
{
"sessionUrl": "https://app.certivant.com/s/01HZ...",
"expiresAt": "2026-05-30T10:00:00.000Z"
}
Email it to the applicant, embed it in your own onboarding flow, or open it in an iframe — whatever fits your UX. When the applicant submits, Certivant moves the request into PROCESSING, runs the checks, and fires the webhook.
On this hosted-session path the applicant also completes email/phone
verification when your organization requires it, so you don't need to
pass emailVerified / phoneVerified yourself. On the server-to-server
path (see Your first request),
verify each required channel — or set those flags on create — before you
call submit.
4 — Listen for the result
Configure a webhook endpoint at KYC → Settings → Webhooks with a URL you control. Certivant will POST to it whenever the request state changes.
{
"event": "kyc.request.approved",
"requestId": "req_01HXY...",
"organizationId": "org_01HW...",
"externalRef": "order-12345",
"status": "APPROVED",
"timestamp": "2026-05-27T10:04:21.000Z",
"data": { "score": 92, "decision": "approve" }
}
Use the externalRef to find the row in your database and proceed with onboarding. See Webhooks for signature verification, retry behaviour, and the full event catalogue.
What's next
- Authentication — scopes, key rotation, environment hygiene.
- Your first request — the same flow without the hosted session (you upload documents yourself).
- KYC requests reference — every endpoint, every field.
- Webhooks — set up signature verification before you go to production.
