This returns a random value called `rhash` that is part of the invoice.
The recipient needs to communicate its ID `<recipient_id>`, `<rhash>` and the desired `<amount>` to the sender.
The sender needs to compute a route to the recipient, and use that route to actually send the payment:
The sender needs to compute a route to the recipient, and use that route to actually send the payment.
The route contains the path that the payment will take throught the Lightning Network and the respective funds that each node will forward.
```
route=$(daemon/lightning-cli getroute <recipient_id> <amount> 1 | jq --raw-output .route -)
daemon/lightning-cli sendpay $route <amount>
daemon/lightning-cli sendpay $route <rhash>
```
Notice that in the first step we stored the route in a variable and reused it in the second step.
