# Generate your first label

Note
If you would prefer to learn how to create your first shipping label using Postman, see our guide to create your [first shipping label using Postman](/docs/guides_general/generate_shipping_label_postman).

Use the Shippo API to programmatically create shipping labels from any supported carrier.
Follow this guide to learn how to create your first label. This guide uses Shippo API objects, to learn more about these read our [API objects guide](/docs/api_concepts/api-objects).

Note
Before starting this guide, follow the [Authentication guide](/docs/guides_general/authentication) to generate your API Token. In these guides, wherever you see `<API_TOKEN>`, replace it with you own token.

When learning about and testing the Shippo API, we recommend using the [test token](/docs/guides_general/testing).
Using your test token means all the calls you make to the Shippo API are free.

## Introduction

There are two ways to create shipping labels with the Shippo API

1. [Create a label with two API calls](#create-a-label-with-two-api-calls)


If you don't know which carrier and service you want to use, use the two API call method. This retrieves all the  available rates for your shipment. You can then choose the rate that works best for you before purchasing it.

1. [Create a label with one API call](#create-a-label-with-one-api-call)


If you already know which carrier and service you want to use, you can create a label with a single API call directly.

## Create a label with two API calls

To retrieve all available rates and create a shipping label based on one of the rates, you need to follow two simple steps:

1. Create the `shipment` object, consisting of two `address` objects (address from and address to) and at least one `parcels` object (blue objects below).
The Shipment response contains the list of available Rates and their associated object IDs.
2. Create the `transaction` object. You pass your chosen `rates` object (green object below) to the transaction call. Calling the transaction endpoint purchases your label.

To create a [Shipment object](/shippoapi/public-api/shipments), call the shipment endpoint `https://api.goshippo.com/shipments/`.

At a minimum, a shipment requires a `address_from`, `address_to`, and `parcels`.

Note
All US addresses are automatically validated. For more information see our [Address Validation guide](/docs/addresses/addressvalidation).

The response includes the `object_id` for the `shipment`, `address_from`,`address_to`, and `parcels` as well as `rates`. These `rates` are the available shipping options for your shipment. Review the returned rates to find the one that works best for your shipment.

Calling the transactions endpoint `https://api.goshippo.com/transactions`, creates a `transaction` [object](/shippoapi/public-api/transactions) and purchases your shipping label.
Use the `object_id` of the `rates` you have chosen from your `shipment`. If your `shipment` has more than one `rates`, select the `object_id` of the rate that works best for you.

You can send an optional `label_file_type` in the transaction call. If you don’t specify this value, the API will use to the default file format, which you can set on the [settings page](https://apps.goshippo.com/settings/account).

## Create a label with one API call

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

Creating an Instalabel with one API call is a POST request to the Transaction endpoint with the nested shipment information, the carrier account, and the service token.

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

**Request:**


```shell cURL
curl https://api.goshippo.com/transactions/  \

The response is the `transaction` object that includes details about the label including a link to your shipping label `label_url`.
Shippo automatically creates the corresponding `rate` object, which you can use to retrieve the `amount` of the label.

## Create a label from selected carriers

Creating a `shipment` will generate rates from all carriers connected with your account (including both Shippo carrier accounts and your own carrier accounts).
You can modify your API call to return rates from your selected carriers.
