You can use the vRealize Automation REST API reservation service to delete an existing reservation.
Log in to vRealize Automation as a fabric group administrator.
Verify that the host name and fully qualified domain name of the vRealize Automation instance are available.
If you are not using the API Explorer, verify that you have a valid HTTP bearer token that matches your login credentials. See REST API Authentication.
Obtain the reservation ID of the reservation that you want to delete. This information is required API command input. See Syntax for Displaying a List of Reservations.
The following example command deletes a reservation with the ID of 94d74105-831a-4598-8f42-efd590fea15c.
curl –X “Delete” --insecure -H "Accept:application/json" -H "Authorization: Bearer $token" https://$host/reservation-service/api/reservations/94d74105-831a-4598-8f42-efd590fea15c
The following output is returned based on the command input.
If the command is successful, the HTTP response body is empty except for a 204 No Content status statement.
