# Instalabel - single call label creation

If you already know what service level you’ll be shipping with, you can create a shipping label in one API call through Shippo using our Instalabel feature.

Note
Instalabel creation is currently only available for a select set of carriers through Shippo. To see if your carrier is supported, see our [carrier capabilities](/docs/carriers/carriercapabilities) page.

If this is your first time using Shippo, we recommend going through the [First Shipment](/docs/guides_general/generate_shipping_label) tutorial to get yourself acquainted with the basic concepts.

## Setup and configuration

1. If you are using your own carrier accounts, make sure to go through the [Carrier Account](/docs/carriers/carrieraccounts) tutorial to add your carrier credentials and connect them with Shippo first.
2. Retrieve the unique carrier account object_id for the carrier that you’d like to use for the single-call request.
3. Take a look at our list of available service level tokens to select the one that you’d like to use for the request.


## Creating labels with one API call

Creating a label with one API call is a POST request to the Transaction endpoint with the nested shipment information, the carrier account and the service token. A sample request looks like this:


```shell
{
    "shipment": {
        "address_from": { 
            // sender address fields
        },
        "address_to": { 
            // recipient address fields
        },
        "parcels": [
            {
                // parcel fields
            }
        ],
        ... // other relevant shipment fields
    },
    "carrier_account": "<carrier-account-object-id>",
    "servicelevel_token": "<servicelevel-token>"
}
```

Here’s a sample call that instantly creates and returns a shipping label:


```shell cURL
curl https://api.goshippo.com/transactions/  \
    -H "Authorization: ShippoToken <API_Token>" \
    -H "Content-Type: application/json"  \
    -d '{
        "shipment": {
            "address_from": {
                "name": "Mr. Hippo",
                "street1": "215 Clayton St.",
                "city": "San Francisco",

            },

The API will respond with the JSON serialized `Shipment` object. Shippo automatically creates the corresponding `rate` object, which you can use to retrieve the `amount` of the label.
