Renewing a Client Secret
Microsoft provides documentation for replacing an expiring or expired client secret in a SharePoint Add-ins, and it should always be the primary source of instructions for updating a client secret. This help page will serve as a guide to updating the client secret but we rely mainly on Microsoft's Client secret documentation since this entire process is controlled by Microsoft and Gimmal is not responsible for the validity and accuracy of instructions over its lifetime.
See the following sections to renew your client secret for the on-premises and Gimmal Cloud versions of the SharePoint Online Connector.
On-Premises

To renew a client secret for SharePoint Online Connector in the Gimmal Cloud, there are some steps you must perform in addition to the steps listed in Microsoft's documentation.

Make note of your Client Secret value.
