How does the PUT endpoint work?

The Label API lets you automatically provide feedback to train SEON’s machine learning models based on your specific business needs. This helps reduce false positives and false negatives by refining detection through customer-specific models.

To label a transaction, you must include its transaction_id. Only transactions that already exist in SEON can be labeled.

• Defined Labels Only: SEON provides a fixed set of positive and negative labels — custom values aren’t accepted.
• One Label per Transaction: Each transaction can have one label at a time. You can overwrite it with a new one.
• Validated Inputs: The API checks each label for accuracy. Invalid inputs will return an error and an HTTP error code.
• Batch Labeling: Label up to 50 transactions at once using the multiple labeling option.
• Case-Sensitive: All label values and API inputs are case-sensitive — use the exact formatting shown in the docs.
