# Reschedule a booking

`PATCH /v3/scheduling/bookings/{booking_id}`

Reschedules the specified booking. Nylas also updates the associated event on the provider.

Nylas recommends against changing participants' email addresses while updating a booking, to avoid
confusion.

Nylas validates the provided session ID and uses it to retrieve the related
[Configuration object](/docs/reference/api/configurations/). If you created a public
Configuration, you don't need to include the `Authorization` request header with a session ID, but
you do need to pass the Configuration object ID as a query parameter.

When you make a `PATCH` request, Nylas replaces all data in the nested object with the information
included in your request. For more information, see
[Updating objects](/docs/reference/api/#updating-objects).
