This sample deletes a route in a project. ## Explore further For detailed documentation that includes this code sample, see the following: - [Use routes](https://docs.cloud.google.com/vpc/docs/using-routes) ## Code sample ### Go Before trying this sample, follow the Go setup instructions in the [Compute Engine quickstart using client libraries](https://docs.cloud.google.com/compute/docs/api/using-libraries). For more information, see the [Compute Engine Go API reference documentation](https://docs.cloud.google.com/go/docs/reference/cloud.google.com/go/compute/latest/apiv1). To authenticate to Compute Engine, set up Application Default Credentials.
