Update Account

As an authorized Mimecast Managed Service Provider, update an existing Mimecast customer account.


  • To use this endpoint the requesting user must be a member of the Partner Provisioning Role.


To use this endpont you send a POST request to:

  • /api/account/update-account

Request Headers

The following request headers must be included in your request:

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

Request Body

 "data": [
   "accountCode": "String", 
   "numberOfUsers": 0, 
   "telephone": "String", 
   "accountName": "String", 
   "contactEmail": "String", 
   "products": [
   "contactName": "String"
accountCode String Required The unique Account Code for the customer account to update.
accountName String Optional Use this to set a new Account Name for the customer account.
contactEmail String Optional Use this to set a new contact email address for the account.
contactName String Optional Use this to set a new contact name for the account.
numberOfUsers Number Optional Use this to update the number of users registered to the account. The value entered will be added to the existing number. For example, if an account has 50 users and you enter a value of 50 here the resulting number of users registered to the account will be 100. To reduce the number of users for an account you can enter a negative number here, for example -50. This is value used for billing purposes.
telephone String Optional Use this to set a new contact telephone number on the account.
products Array Optional An array of product ID's that should be enabled for the new account. Each partner will have different agreements with Mimecast. Use the /api/provisioning/get-packages endpoint to discover the product ID's that you are authorized to provision. You must ensure that all product ID's that should be enabled on the customer account are provided here, not just the ones you are adding / removing.
