Search File Hash

Description

      This endpoint can be used to identify if an account has seen a specific file hash within messasges over the last year. A maximum of 100 hashes can be submitted in a single call, however we recommend submitting no more than 20 hashes per API call to stay under the 2048 byte size limit. Note: Currently this endpoint does not support image file hashes.

Pre-requisites

  • In order to successfully use this endpoint the logged in user must be a Mimecast administrator with at least the Services | Threat Remediation | Read permission.

URI

To use this endpoint you send a POST request to:

  • /api/ttp/remediation/search-hash

Request Headers

The following request headers must be included in your request:

Field Description
Authorization Please see the Authorization guide for more information on building the Authorization header.
