Core Requirements
While you have the flexibility to choose a Scan ID that aligns with your internal system, there are a few limitations to keep in mind:- Character Length: Must be between 3 and 36 characters.
- Allowed Characters: The Scan ID can include lower case characters
a-z, digits0-9and special symbols!@$&-=_()';:.,~. We recommend using lower case letters, digits and dashes for simplicity. - Reserved word: Scan IDs that contain
g, then one or moreoor0, thengle(for examplegoogle,gogle,g00gle) are rejected.
Strategies for Naming Your Scan ID
The best approach is to create a structured Scan ID that embeds useful information. This allows you to easily identify a scan based on its scan ID and use advanced features like include or exclude specific groups of documents from a scan.Recommended Structure
A highly effective structure is:<ORGANIZATION_ID>-<AUTHOR_ID>-<DOCUMENT_ID>
Examples
tech-corp-employee456-q3-reportacme-university-student123-final-thesis
Handling ID Mismatches
If your internal system uses IDs that don’t meet Copyleaks’ requirements (e.g., they are too long or contain uppercase letters), the recommended solution is to generate a compliant Scan ID and maintain a mapping table on your end. This table will link your internal entity ID to the corresponding Copyleaks Scan ID, ensuring seamless integration.Next Steps
