+You can set the shipping method for your users' physical cards. To do so, select the `shippingProvider` option in the `physicalCardCustomOptions` input when you [add a card](https://api-reference.swan.io/mutations/add-cards/). 
+Choose from the following options:
+
+- `LaPosteTracked`
+- `LaPosteUntracked`
+- `CorreosTracked`
+- `CorreosUntracked`
+- `DHL`
+- `NACEX`
+
+Make sure to select a shipping provider that's compatible with both the printing hub and the destination country that you chose. 
+Selecting an incompatible provider will return an [`InvalidShippingProviderRejection`](https://api-reference.swan.io/objects/invalid-shipping-provider-rejection/) error.
