There are two ways to use a carrier account with Shippo.

The first is to [use Shippo's account](#use-the-shippo-carrier-account) with your preferred carrier to create shipping labels.
Using Shippo's account makes it easier to get started and means you benefit from the shipping discounts that Shippo has negotiated with the carrier.

The second way is to [use your own account](#use-your-own-carrier-account) with your preferred carrier and share your account details with Shippo. This is useful if you have negotiated your own shipping discounts with your preferred carrier. You can still use all the supported Shippo features.

## Use the Shippo carrier account

To use the Shippo, Colissimo account, you must retrieve the carrier account `object_id`.
This step should only be completed once. In future transactions, you can use the carrier `object_id` to reference your carrier.

Note: If you did not receive a response like this, the carrier may not have been enabled for your account. Contact [Shippo support](https://support.goshippo.com/hc/en-us/requests/new?_ga=2.259093706.1751315872.1670840488-750891451.1658151685) for more infomation.

Once you have retrieved the `object_id` for your carrier, proceed to [Step 2: Create shipment](/docs/carriers/integration_guides/colissimo/create_shipment).

## Use your own carrier account

If you want to use your own Colissimo account, follow this guide to add your Colissimo account to Shippo. After adding your account, Shippo can use your account details for generating shipping rates and creating labels.
This step requires you to have your Colissimo account id and password.

This step should only be completed once. When you have created your carrier account, you can use the carrier `object_id` to reference your carrier.
