NOTE: When configuring the Remedyforce endpoint in xMatters, if you're installing in a sandbox, the Access Token URL must be the following: https://test.salesforce.com/services/oauth2/token

Thanks Andrew! I've added that note directly into the configuration steps.

Updated the link to download the xMatters installation package in Remedyforce.

Updated the default endpoint setting in the attached communication plan and the endpoint instructions to streamline setup.
