Create Remediation Incident


This endpoint can be used to create a remediation incident, by messageId or file hash. A successful call will return the incident information, and will take the same actions as a manual remediation incident created in the Administration Console. Note: Currently this endpoint does not support image file hashes.


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


To use this endpoint you send a POST request to:

  • /api/ttp/remediation/create

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.

A randomly generated GUID, for example,

x-mc-app-id The Application ID provided with your Registered API Application.

The current date and time in the following format, for example,

Tue, 24 Nov 2015 12:50:11 UTC
