Use this endpoint to Create Custom Master Email Template Settings. Settings exist for showing or hiding email panels and for changing color schemes. Use the GET /setup/v1/companies/email/templates endpoint to display the settings offered. Changes to the Master Template Settings will be reflected in all business locations associated with this company.
The email template endpoints work a little differently than most. There are no endpoints to update the templates, we use the post endpoint to create a custom template instead. This endpoint creates a new custom Master Template Settings file that will be used instead. If you delete it you are deleting the custom template settings you created and the original default Master Template created by OnSched would be reactivated.
