Update a Load Balancer

by
Published Dec 20, 2024

To update a load balancer's settings, send a PUT request to `/v2/load_balancers/$LOAD_BALANCER_ID`. The request should contain a full representation of the load balancer including existing attributes. It may contain _one of_ the `droplets_ids` or `tag` attributes as they are mutually exclusive. **Note that any attribute that is not provided will be reset to its default value.**
