List KYC Validations for Entity

Overview

This endpoint retrieves the complete history of KYC validations for a specific entity. This is useful for auditing, compliance tracking, and understanding an entity’s verification journey. Key features:

Returns all validations (current and historical) for an entity
Supports pagination for large validation histories
Includes full verification details for each validation
Ordered by creation date (most recent first)
Shows which validation is currently active

When to Use This

Audit verification history: View all KYC attempts and their outcomes
Compliance reporting: Track verification attempts for regulatory compliance
User support: Investigate why a user’s verification failed or succeeded
Analytics: Analyze verification success rates and abandonment patterns
Debugging: Troubleshoot verification issues by reviewing the full history

Request

Endpoint

GET https://api.gu1.ai/api/kyc/entities/{entityId}/validations

Path Parameters

entityId

string

required

The UUID of the entity to retrieve validations for

Query Parameters

page

integer

default:"1"

Page number for pagination (starts at 1)

limit

integer

default:"100"

Number of validations per page (max 100)

rejected - Verification failed
expired - Validation expired (user didn’t complete in time)
abandoned - User started but didn’t complete
cancelled - Validation was cancelled by organization

isCurrent

boolean

Filter to show only the current active validation (true) or historical validations (false)

{
  "error": "UNAUTHORIZED",
  "message": "Invalid or missing API key"

Use Cases

1. Audit Trail for Compliance

Track all verification attempts for regulatory compliance:

async function getVerificationAuditTrail(entityId) {
  const response = await fetch(
    `https://api.gu1.ai/api/kyc/entities/${entityId}/validations`,
    {
      headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
    }
  );

  const result = await response.json();

  // Generate audit report
  const auditReport = result.validations.map(v => ({
    validationId: v.id,
    status: v.status,
    provider: v.provider,
    createdAt: v.createdAt,
    completedAt: v.verifiedAt || v.updatedAt,
    isCurrent: v.isCurrent,
    manualAction: v.metadata?.manuallyApprovedBy || v.metadata?.manuallyRejectedBy,
  }));

  return auditReport;
}

2. Calculate Success Rate

Analyze verification success rates:

async function calculateSuccessRate(entityId) {
  const response = await fetch(
    `https://api.gu1.ai/api/kyc/entities/${entityId}/validations`,
    {
      headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
    }
  );

  const result = await response.json();
  const validations = result.validations;

  const completed = validations.filter(v =>
    ['approved', 'rejected'].includes(v.status)
  );

  const approved = validations.filter(v => v.status === 'approved');
  const rejected = validations.filter(v => v.status === 'rejected');
  const abandoned = validations.filter(v => v.status === 'abandoned');

  return {
    total: validations.length,
    completed: completed.length,
    approved: approved.length,
    rejected: rejected.length,
    abandoned: abandoned.length,
    successRate: completed.length > 0
      ? (approved.length / completed.length * 100).toFixed(2) + '%'
      : 'N/A',
    abandonmentRate: validations.length > 0
      ? (abandoned.length / validations.length * 100).toFixed(2) + '%'
      : 'N/A',
  };
}

3. Find Failed Validations for Support

Help users who had verification issues:

async function findFailedValidations(entityId) {
  const response = await fetch(
    `https://api.gu1.ai/api/kyc/entities/${entityId}/validations?status=rejected`,
    {
      headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
    }
  );

  const result = await response.json();

  // Extract failure reasons
  const failures = result.validations.map(v => ({
    validationId: v.id,
    rejectedAt: v.updatedAt,
    reason: v.metadata?.rejectionReason || 'Not specified',
    warnings: v.warnings || [],
    decision: v.decision,
  }));

  return failures;
}

4. Export Validation History

Export complete validation history for reporting:

async function exportValidationHistory(entityId) {
  const validations = await getAllValidations(entityId); // From pagination example

  // Convert to CSV format
  const csv = [
    'Validation ID,Status,Provider,Created At,Verified At,Is Current',
    ...validations.map(v =>
      `${v.id},${v.status},${v.provider},${v.createdAt},${v.verifiedAt || ''},${v.isCurrent}`
    )
  ].join('\n');

  return csv;
}

Important Notes

Default Pagination

By default, this endpoint returns up to 100 validations per page. If an entity has more than 100 validations, you’ll need to use pagination to retrieve all records.

Ordering

Validations are returned in descending order by creation date (most recent first). The current validation will typically appear first in the list.

isCurrent Flag

Only one validation per entity can have isCurrent: true at a time. When a new validation is created, the previous current validation is automatically marked as isCurrent: false.

Historical Data Retention

All validations are retained indefinitely for audit and compliance purposes. Historical validations are never deleted, even if they’re abandoned or expired.

Performance Considerations

For entities with many validations (>100), consider using pagination and status filters to reduce response size and improve performance.
