# Response messages

The `messages` array in the API response contains human-readable explanations for integrators.
Messages appear when verification behaved unexpectedly or could not produce a complete result.

Clients should **not** build validations or business logic on messages.

## Warnings

- W001: "The image quality is below the configured verification threshold. Ensure the image is sharp, well-lit, and free of blur or glare."
- W002: "Only one side of a multi-sided document was received. Supply the missing side for complete verification and higher confidence."
- W003: "The barcode could not be read. Ensure it is fully visible, in focus, and free of blur or glare. If available, supply a separate barcode image."
- W004: "Screen-presence, photocopy, and generative-AI checks were not performed because verificationContext is InPerson."
- W005: "This document version is not accepted for verification."
- W006: "The document is expired and rejectExpiredDocuments is enabled, resulting in a Reject verdict." 
- W007: "Verification completed using only the first side because the second side could not be used. Supply a clear image of the matching second side for a more complete result."
- W008: "The document is cropped or too close to the image edges, preventing a conclusive verification result. Supply an uncropped image with all document edges visible."
- W009: "The supplied image appears to be the wrong document side while the first side is still required. Supply a clear image of the first side to continue verification."

## Information

- I001: "Despite the image-quality warning, verification returned an Accept verdict under the configured image-quality retry policy."
- I002: "Cropping did not block verification because cropAffectsVerdict was false."
- I003: "The document is expired, but rejectExpiredDocuments is disabled, so expiration did not affect the verification verdict."
