This invoice starts with prefix ln+tb+1m that indicates milli, so you should multi by 0.001. That means we'll pay an invoice by 100000 satoshis.
### Understanding your invoice
+If you want to decode your lightning invoice you should use `lightning-cli decodepay ` command that receives a string and checks and parses as specified by the [BOLT 11 specification](https://github.com/lightningnetwork/lightning-rfc/blob/master/11-payment-encoding.md).
