Overview

This endpoint allows you to manually approve a KYC validation. When you approve:
  • Automatic sync with provider: The system first syncs with the KYC provider to get the latest verification status
  • Status validation: You can only approve if provider status is in_review (user has completed verification and requires manual review from compliance team)
  • The validation status changes to approved
  • The validation is marked as verified with timestamp
  • The approval reason is saved in metadata and audit logs
Manual approval should only be used when you’ve performed additional verification or have sufficient reason to override the automated process. The approval reason is required for audit compliance.

​
When to Use This

  • Additional verification completed: You’ve performed manual review of documents or biometric data
  • Business exception: You have business reasons to approve despite minor issues
  • Risk assessment override: Your risk team has approved the validation
  • Provider delay: The verification provider is taking too long but your internal review is complete

  `https://api.gu1.ai/api/kyc/validations/${validationId}/approve`,
  {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      'Content-Type': 'application/json',

​
Error Responses

​
Validation Not Found (404)

{
  "error": "NOT_FOUND",
  "message": "Validation not found"
}

​
Invalid Status (400)

Validation can only be approved if provider status is in_review (user has completed verification and requires manual review from compliance team): 
{
  "error": "INVALID_STATUS",
  "message": "Cannot manually approve. Current status is \"approved\". Manual approval is only allowed when status is \"in_review\" (validation requires manual review from compliance team)."
}
What this means:
  • If the provider already approved (approved) or rejected (rejected) the validation, you cannot override that decision
  • If the validation is cancelled, you cannot approve it
  • If it’s expired or abandoned, it also cannot be manually approved
  • If it’s in_progress, the user is still filling out the verification form
  • You can only approve when the provider reports the validation as in_review (user has completed all verification steps and requires manual review from compliance team)

​
Invalid Reason (400)

Reason must be at least 5 characters: 
{
  "error": "VALIDATION_ERROR",
  "message": "Reason must be at least 5 characters"
}

​
Important Notes

Before approving, the system automatically syncs with the KYC provider to get the latest verification data. This ensures you’re making decisions based on the most recent information.
You cannot approve validations that are already approved, rejected, or cancelled. These statuses are protected to maintain data integrity.
The approval reason is saved in both the validation metadata and audit logs. This is critical for compliance and regulatory requirements.
Manual approval is only allowed when the provider reports the validation as in_review. This prevents approving validations that:
  • The provider has already declined or completed
  • Don’t have complete verification data (status pending or in_progress)
  • The user is still filling out the form (status in_progress)
When approved, the validation receives a verifiedAt timestamp and becomes the current validation for the entity.

​
Best Practices

  • Always provide detailed reasons: Include specific details about why manual approval is necessary
  • Document your process: Maintain internal documentation for manual approval criteria
  • Review fresh data: The automatic sync ensures you see the latest documents and biometric results
  • Use sparingly: Manual approval should be the exception, not the rule
  • Train your team: Ensure staff understand when manual approval is appropriate
