The `Invoice Shipping node` is required when an invoice is sent to the Telegram client with the flag _isFlexible_: that means that the shipping options need to be calculates based on the destination and/or the goods that are to be delivered.
When this happens a message type _invoice-shipping_ is received from the chatbot, at this point is mandatory to answer with a `Invoice Shipping node` with the proposed shipping options and related prices. The total amount charged to the user’s credit card will depend on the selected shipping option.
Use a [Rules node](https://app.notion.com/p/4113636f565d4ff4af08bc61a644206b) to redirect the incoming messages with type _invoice-shipping_ to the subflow that handles the aswer. It’s also a common use case to calculate dinamically the shipping options in a `Function node`
And in the upstream `Function node`
```javascript
msg.payload.shippingOptions = [
{ id: 'FEDEX', label: 'FedEx', amount: 9.99 },
{ id: 'DHL', label: 'DHL', amount: 11.99 },
];
return msg;
```
