API to trigger a Workflow attached to a Calendar Event

Hi team,

I am collecting information from leads via Whatsapp. After getting email and phone in Whatsapp I will use your endpoint to create the contact.

https://{subdomain}.myclickfunnels.com/api/v2/workspaces/{workspace_id}/contacts

Then, we need that customer to start flowing into a workflow. When I collected information of the customer in a landing form, I triggered a Workflow with the following Event Type

Calendar Event - Contact Registered

I need it because the workflow manages specific actions relative to the event's start time.

However, I can't see how to put everything together using your endpoint collection.

Any guidance is more than welcome. Thanks in advance.
