Hello @ilovelaw!

If you’ve changed the event type’s language to French, the booking page and all event notifications for this event will be in French. More on that here: https://help.calendly.com/hc/en-us/articles/14075885394071-Event-type-language-options#event-type-language-options-0-0

However, if you want to create an extra custom - as in specific to this event only - workflow, you certainly can! In this situation, you’d create workflows as you normally would but give the workflow a name specific to the French language event and only apply it to the French language events. Keep in mind they’ll be translated already, even if you’re seeing them in English or another language.

Hope this helps!
