# List external API calls

> List external API call steps, optionally filtered by action or attribute.

Returns external API call records in the workspace. The wire-format object is still called [`Data Step`](/en/api-reference/actions-and-attributes#data-step-object). Pass `toolId` to list only the calls for one action or attribute, ordered by `stepNumber`.

## Headers

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

## Query parameters

<ParamField query="toolId" type="string">
  Optional action or attribute ID. When set, returns only that record's external API calls, ordered by `stepNumber`.
</ParamField>

## Response

Returns a top-level array of [`Data Step`](/en/api-reference/actions-and-attributes#data-step-object) objects with sensitive values masked.
