I created the IBM Cloud Identity and ServiceNow Integration Setup Guide document for an example of adding ServiceNow to your IBM Cloud Identity (CI) tenant. In that document I stated “This document assumes you have an existing CI tenant and have some knowledge of CI administration. If you do not have a CI tenant, please see other collateral to acquire your own CI tenant”. However, I have not found any “other collateral” to acquire a trial CI tenant. Therefore, I am posting the instruction below to help you acquire a no charge, trial, CI tenant.
You will need an IBMid in order to obtain the trial. If you do not have an IBMid, you can get one here: https://www.ibm.com/account/us-en/signup/register.html
You will need an e-mail address to receive initial account information and e-mail One-Time Passwords. You can use a single e-mail address for all requirements in this document.
You will need a mobile number to receive SMS One-Time Passwords. You can use a single number for all requirements in this document.
Anyone with an IBM ID can sign up for an IBM Cloud Identity Connect trial from the IBM Marketplace. Open a new browser window and navigate to:
