GET - Evidence

Overview

This endpoint retrieves a paginated list of all evidence associated with a specific investigation. By providing the investigationId, you can fetch all related artifacts, and you can use query parameters to filter by evidence type and navigate through the results. Use this API to retrieve the specific artifacts (like devices, IPs, or file hashes) linked to an investigation. It's the next logical step after identifying a case of interest, allowing your workflow to extract the raw data needed for enrichment, correlation with other systems, or direct remediation actions.

Authentication

Authentication type: Bearer Token, API Key.

You can create a token using client credentials obtained through the developer portal. The API Key (x-api-key) is provided in your onboarding email or on the API Access Management page.

Request

Request headers

Authorization: Bearer <your_bearer_token>
Content-Type: application/vnd.api+json
x-api-key: <your_api_key>
Accept-Encoding: gzip

Authorization: This header is used to authenticate your request. You need to replace <your_bearer_token> with the actual token you generate.
Content-Type: This header tells the server that the request body format is json:api. Even though this specific call has no request body, the API requires this header.
x-api-key: This is a custom header required by the Trellix API for authentication. You'll need to replace <your_api_key> with the key from your onboarding email or the API Access Management page.
Accept-Encoding: This is an optional header you can include to tell the server you can accept a compressed response (using gzip), which can make the data transfer faster.
