When triggering a flow with a webhook, it would be great if we could pass values that will not be stored in the contact but just used for that flow.

Say I have a flow for inviting people to a webinar, I would of course include their user ID to trigger the flow for them, but I'd love to also be able to pass along some parameters that are used in that particular flow, such as the title and date of the webinar, link to sign up, etc.

This would mean I would just need a single flow for all similar webinars, and I could trigger them with a webhook for each person I wanted to invite.
