Create Classifier

POSThttps://api.confident-ai.com/v2/classifiers

Creates a classifier that tags incoming traces or threads with labels, and returns its id. A name is unique per data model within the project. Sending a preset seeds the classifier with a description, a generation config, and a starting set of labels; any field you send explicitly overrides what the preset would have set. SENTIMENT arrives with its labels ready, while USE_CASES and ISSUES ship with none and expect a generation run next. Retrieve the classifier by id to read back what the preset seeded. Requires the Starter plan or above.

Headers

CONFIDENT_API_KEYstringRequired
The API key of your Confident AI project.

Request body

namestringRequired
The name of the classifier, unique per data model within the project.
dataModelenumRequired
What kind of production item a classifier labels: TRACE labels individual traces, THREAD labels whole conversations. It is fixed when the classifier is created.
Show 2 enum valuesHide 2 enum values
- TRACE
- THREAD
presetenum
A Confident AI template to seed a classifier from. SENTIMENT arrives with its labels ready; USE_CASES and ISSUES ship with none and expect a generation run next. CUSTOM seeds nothing.
Show 4 enum valuesHide 4 enum values
- CUSTOM
- SENTIMENT
- USE_CASES
- ISSUES
descriptionstring | null
What this classifier is for. Send null to clear it.
enabledboolean
Whether the classifier runs at all. Defaults to true.
autoClassifyboolean
Whether incoming items are classified automatically as they arrive. Defaults to true.
filtersobject | null
A set of filter groups combined by a top-level operator. Each group combines its filter rows by its own operator, and each row matches one property, such as Name or User Id, against a value with a condition such as Is or Contains.
