# Test attribute

> Run the whole attribute with sample inputs.

Runs the full Data Step chain for one attribute against sample inputs and returns the resolved outputs. This mirrors the dashboard Run button.

## Headers

<ParamField header="Authorization" type="string" required>
  Bearer token containing your Fini workspace API key. Format: `Bearer fini_...` The key needs `write` scope.
</ParamField>

<ParamField header="Content-Type" type="string" required>
  `application/json`
</ParamField>

## Path parameters

<ParamField path="id" type="string" required>
  Attribute ID to run.
</ParamField>

## Body parameters

<ParamField body="inputParams" type="object">
  Optional sample inputs, keyed by input field name. These stand in for the runtime values the attribute would resolve at the start of a conversation.
</ParamField>

## Response

Returns an [`Action / Attribute test-run result`](/en/api-reference/actions-and-attributes#action-or-attribute-test-run-result) with per-step results and the final `extractedData`. For attributes, `attributeLlmPolicy` maps each output field to its `sendToLlm` (Visible to AI) flag.
