# Creating packages
If you need to have packages in requests we send to you, you can define them in the Packages section. You can then use packaging variables in the requests to get the package the merchant chooses.
## Create a package

## Merchant perspective
When you define packages, a merchant will see them on the integration page. They will be able to
* Select their default package
* Set the weight threshold for each package

## Variables
Please take a look at our [packaging variables](https://partners.zapiet.com/docs/last-mile/allowed-variables) in the variable guide. You can then reference them in requests like any other variable. For example, ####{{ package.length }}
Now it’s time to start creating requests—first one is the rate estimate.
