Overview - How to stop the Salesforce trigger from being activated from Sandbox activity.
Cause - When a Salesforce Sandbox is created or refreshed, all environment outbound messages and metadata from Production are also copied over.
Check the Outbound Messages configuration under Process Automation -> Workflow Actions -> Outbound Messages.
This can be accessed from the environment Settings, then type "outbound messages" in the quick find search box.
This will display a page with all outbound webhook triggers.
Filter for Tray triggers using the naming convention "TrayOn..." For example, "TrayOnOpportunityFieldChange__"
Check the list for whether the sandbox is configured to send webhooks to Tray.
If your Sandbox environment contains a workflow automation to send data to a Production workflow, either deactivate or delete it.
