When performing Document Verification, the API returns structured results for multiple categories of checks. Each individual check can return one of the following statuses:
  • Pass
  • Fail
  • Not Performed
This page explains:
  • What each status means
  • What supported vs not supported means
  • How checks influence the overall verification result

​
Check Status Meanings

Pass A check returns Pass when:
  • The check is supported for the uploaded document type
  • The check was successfully executed
  • No issues or anomalies were detected
A Pass contributes positively toward the overall verification result.
Fail A check returns Fail when:
  • The check is supported for the selected document type
  • The check was successfully executed
  • An issue or inconsistency was detected
A Fail contributes negatively toward the fraud or verification decision.
Not Performed Not Performed does not mean failure. It means the check was not executed. This can occur when:
  1. The check is not supported for the document type
  2. The check is disabled in configuration
  3. The check could not run due to:
    • Image quality issues
    • Missing or unreadable data
    • Processing or technical limitations
    • Incomplete capture (Both document side requirement)
When a check returns NotPerformed:
  • It does not affect the fraud decision
  • It does not count as Pass or Fail
  • It is excluded from scoring logic

​
What Does “Supported” Mean?

On the Supported Documents page, each document type lists which verification checks are available. Example:
DocumentOCR/Data ExtractionVisual ChecksLiveness CheckData CheckSupported Side
Alien ID✓✗✓✓Front & Back
Driver’s License✓✓✓✓Front & Back
Identity Card✓✓✓✓Front & Back
Multipurpose ID✓✗✓✓Front
Nbi Clearance✗✗✓✗-
Paper Passport✓✓✓✓Bio-data Page
Supported (✓) If a check is marked as supported:
  • The verification engine is capable of running the check
  • If enabled and successfully executed, it will return Pass or Fail
  • If execution is not possible, it may return NotPerformed
Not Supported (✕) If a check is marked as not supported:
  • The verification engine cannot run this check for the document type
  • The result will always be NotPerformed
  • The check will never return Pass or Fail
Unsupported checks are structurally excluded from fraud evaluation.

​
Visual Checks

Visual checks analyze the authenticity and integrity of the document image. These may include:
  • PhotoForgeryCheck
  • SecurityFeatures
  • GenerativeAiCheck
When Visual Checks Are Supported
  • Sub-checks return Pass or Fail
  • Results influence fraud scoring
When Visual Checks Are Not Supported
  • Sub-checks return NotPerformed
  • Results do not influence the verification outcome
Example response: 
{
  "PhotoForgeryCheck": "NotPerformed",
  "GenerativeAiCheck": "Pass"
}
Interpretation
  • Generative AI detection was supported and passed
  • Photo forgery analysis was not executed
  • Only executed checks contribute to the fraud decision

​
Document Liveness Check

Document liveness checks determine whether the document presented appears to be:
  • A real physical document
  • Not a screen replay
  • Not a photocopy
Examples include:
  • ScreenCheck
  • PhotocopyCheck
If supported:
  • Returns Pass or Fail
  • Contributes to fraud evaluation
If not supported:
  • Returns NotPerformed
  • Does not affect the verification result

​
Extracted Data Check

Extracted data checks validate OCR results and data consistency. These may include:
  • FieldFormatCheck
  • LogicCheck
  • SuspiciousDataCheck
  • DataIntegrityCheck
  • BarcodeAuthenticity
If supported:
  • Validation rules are executed
  • Returns Pass or Fail
If not supported:
  • Returns NotPerformed
  • Excluded from fraud scoring

​
Document Validity Check

The DocumentValidityCheck determines whether a document is legally valid for identification purposes. This may include:
  • ExpiredCheck — verifies whether the document is expired
  • VersionCheck — verifies whether the document version is still accepted by the issuing authority
If supported:
  • Returns Pass or Fail
  • Influences the verification decision
If not supported:
  • Returns NotPerformed
  • Does not influence the result

​
How the Overall Verification Decision Works

Only checks that:
  • Are supported
  • And were successfully executed
can influence the overall fraud or verification decision. Checks marked as NotPerformed:
  • Are excluded from calculation
  • Do not reduce trust
  • Do not increase trust

Key Takeaways

  • NotPerformed is not an error
  • Unsupported checks are intentionally excluded
  • Only executed checks (Pass or Fail) affect the final result
  • Different document types support different verification layers
