Manage KYC onboarding sessions for end users. Sessions track progress through workflows, store document uploads, and manage the onboarding process from creation to approval.

Overview

Sessions represent individual KYC onboarding processes for end users. Each session:

Links to a Workflow: Defines the steps and requirements
Tracks Progress: Monitors which steps are completed
Stores Documents: Uploaded documents are stored securely
Runs Validations: Automated checks (watchlists, crypto, adverse media, face match)
Public Access: End users access sessions via public access tokens

Endpoint

POST /kyc/sessions

Request Body Parameters

Subject data

Use subject_data to declare facts your integration already knows about the subject before the end user opens the public link. Values are stored on the session, echoed in GET /kyc/sessions/{session_id}, and consumed during processing. Each value may be a plain scalar or an envelope object:

"website": "https://merchant.example"

"website": {
  "value": "https://merchant.example",
  "validation_profile": "web_validator_default"
}

Website URL (web validation)

If any of the following keys holds a non-empty URL string, the platform runs web validation for that URL when the session is processed — even when the end user never fills a website field in the public form:

Key	Notes
`website`	Recommended. Aligns with the `website` form field in KYB/merchant workflows
`web_url`	Alias
`url`	Alias
`domain`	Alias

Duplicate URLs are validated once. If the workflow also has an auto-validated URL form field and the user submits the same URL, you are not charged twice. Optional companion keys improve the web validator context (same semantics as POST /kyc/web-validation):

Key	Used for
`legal_name`, `business_name`, `company_name`, `full_name`, `name`	`declared_name` passed to the web validator
`industry`, `business_industry`, `sector`	`declared_industry`
`merchant_id`, `client_id`, `customer_id`	Merchant/customer correlation (falls back to the session’s `customer_id` when linked)

Declaring a URL in subject_data consumes one web_validation_checks unit at session creation, the same as when the workflow defines an auto-validated URL field. Processing runs automatically when the session completes if the workflow has auto_process enabled (default for most templates).

Web validation summary (triggered automation rules) is delivered in session webhooks. The full web_validation_results payload is available via the Sessions API after processing — see Web validation results.

Individual KYC (pre-declared person)

For individual identity workflows (IDV / KYC), pass attributes you already know about the person in subject_data at creation time. The platform stores them on the session and uses them during processing — before the end user completes the public form.

Key	Notes
`full_name`	Recommended for natural persons. Drives sanctions screening and adverse media as a declared screening subject (`source: "subject_data"`)
`name`	Alias for `full_name`
`nationality`	ISO alpha-2 (e.g. `UY`). Feeds automation country rules
`country_of_residence`, `residence_country`	Country of residence for automation
`date_of_birth`	Stored on the session and included in reports; use form fields for cross-validation against documents
`document_number`, `tax_id`, `email`	Stored and available to automation rules and reports

subject_data is tenant/backend data. It is not returned by the public session API and does not pre-fill the end-user form. Cross-validation compares what the user declared in the public form against extracted document data — not your pre-declared subject_data.

Example — create a session when you already know the subject is Federico Gil:

{
  "workflow_id": "550e8400-e29b-41d4-a716-446655440000",
  "client_id": "federico-gil-123",
  "metadata": {
    "user_email": "federico@example.com",
    "user_name": "Federico Gil"
  },
  "subject_data": {
    "full_name": "Federico Gil",
    "nationality": "UY",
    "date_of_birth": "1990-05-15"
  }
}

After the session completes and is processed, check processing_results.external_validations.lists_check — when the workflow has validation_config.run_lists enabled, screening includes a subject with "source": "subject_data" even if the user has not yet filled the public form:

{
  "screening_subjects": [
    {
      "name": "Federico Gil",
      "source": "workflow",
      "entity_type": "individual",
      "role": "primary"
    },
    {
      "name": "Federico Gil",
      "source": "subject_data",
      "entity_type": "individual",
      "role": "declared"
    }
  ],
  "entities_checked": ["Federico Gil"]
}

Unlike website URLs, declaring a person name in subject_data does not consume extra quota at creation. Sanctions screening only runs when the workflow has run_lists: true (or equivalent automation configuration).

The custom_tags field is a snapshot of the workflow’s custom_tags at the time the session was created. If you later update the workflow’s tags, existing sessions retain their original tags. These tags are included in all session webhook payloads.

Summary Statistics

When include_summary=true, the response includes aggregate statistics for all sessions matching the filters (not just the current page):

Field	Description
`status_counts`	Count of sessions per status
`inbox_counts`	Count of sessions per operational inbox
`total`	Total number of sessions matching filters
`avg_risk_score`	Average risk score across scored sessions
`sessions_with_risk_score`	Number of sessions that have a risk score
`validation_counts`	Count of sessions that executed each validation type

The summary requires scanning all matching sessions, which may increase response time for tenants with many sessions. Use filters (workflow_id, date range) to limit the scope when possible.

  }
}

Processing Results Fields

Field	Description
`extraction_results`	Extracted data from each uploaded document
`cross_validation`	Consistency check between documents and form data
`face_match_result`	Face comparison between ID and selfie (if configured)
`external_validations`	Results from watchlist, crypto, and adverse media checks
`web_validation_results`	URL validation results (if configured)
`final_decision`	Automatic decision: `approved`, `flagged`, `manual_review`, or `rejected`

Web validation results

Each entry in processing_results.web_validation_results corresponds to one URL that was validated — from a workflow form field with auto_validate, or from subject_data at creation time.

Field	Description
`field_id`	Workflow field ID, or `subject_data.{key}` when the URL was declared via `subject_data`
`step_id`	Form step ID, or `subject_data` for pre-declared URLs
`url`	Validated URL
`status`	`success` or `error`
`result`	Full web validation payload on success (same shape as `POST /kyc/web-validation`)
`error`	Generic error code on failure (`invalid_url`, `validation_failed`). No URL or internal details are returned

Retrieve results with:

GET /kyc/sessions/{session_id} — after status is processed, approved, rejected, or manual_review
POST /kyc/sessions/{session_id}/process — triggers processing manually and returns the same processing_results object

Session webhooks include web validation decisions inside automation_result.triggered_rules (e.g. web_ssl, web_industry, web_score), not the full web_validation_results array. See Session webhooks — web validation.

Update Session Status

Manually update the status of a session. Use this endpoint for reviewer decisions and operational transitions such as reactivating a session.

Endpoint

PATCH /kyc/sessions/{session_id}

Request Body Parameters

Request Example

curl -X PATCH https://kyc.legaltalent.ai/kyc/sessions/660e8400-e29b-41d4-a716-446655440001 \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "status": "approved",
    "notes": "All documents verified successfully"
  }'

Response Format

{
  "status": "success",
  "data": {
    "session_id": "660e8400-e29b-41d4-a716-446655440001",
    "status": "approved",
    "updated_at": "2024-11-22T10:50:00Z"
  }
}

Request Client Corrections

Request remediation from the end user for specific workflow steps, fields, or document types. The session moves to awaiting_client_correction, affected steps move to needs_correction, and the existing public access link remains valid. Use this when a reviewer needs the customer to fix submitted data or replace documents instead of approving or rejecting immediately.

Endpoint

POST /kyc/sessions/{session_id}/corrections

Request Body Parameters

Each item in corrections supports:

Field	Type	Description
`step_id`	string	Workflow step that needs correction
`field_ids`	array	Optional form field IDs to correct
`document_types`	array	Optional document types to replace or re-upload
`message`	string	User-visible instructions shown in the public session

Request Example

curl -X POST https://kyc.legaltalent.ai/kyc/sessions/660e8400-e29b-41d4-a716-446655440001/corrections \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "corrections": [
      {
        "step_id": "personal_info",
        "field_ids": ["full_name"],
        "message": "Please correct your legal name so it matches your ID."
      },
      {
        "step_id": "id_document",
        "document_types": ["id"],
        "message": "Please upload a clearer photo of your ID."
      }
    ],
    "comment": "Name mismatch and blurry ID image"
  }'

Response Format

{
  "status": "success",
  "data": {
    "session_id": "660e8400-e29b-41d4-a716-446655440001",
    "status": "awaiting_client_correction",
    "current_step_index": 0,
    "steps_data": [
      {
        "step_id": "id_document",
        "status": "needs_correction",
        "correction_requests": [
          {
            "id": "corr_abc123",
            "step_id": "id_document",
            "document_types": ["id"],
            "message": "Please upload a clearer photo of your ID.",
            "status": "open"
          }
        ]
      }
    ]
  }
}

When corrections are requested, any current terminal final_decision fields are cleared so the session is no longer displayed as currently approved or rejected while remediation is pending.

Typical Workflow

Create Session: Create a session linked to a workflow. Optionally pass subject_data (e.g. website for merchants, or full_name / nationality for individual KYC) with data you already know
Share Link: Send the access_link to the end user
User Completes Steps: User uploads documents and fills forms via public API
Subsessions (if applicable): User creates subsessions for UBOs/submerchants via the public API
Process Session: Processing runs automatically when the session completes if the workflow has auto_process enabled; otherwise call POST /process
Review Results: Read processing_results via GET /kyc/sessions/{session_id} (full detail) or act on kyc.session.processed webhooks (automation summary)
Request Corrections (optional): Move the session to awaiting_client_correction with POST /corrections
User Resolves Corrections: The public link shows only the affected steps and open correction guidance
Final Decision: Update status to approved or rejected if manual review is needed
