You can update your Addresses either directly through the Console or by using our REST API.
To update your address using the Console, you'll want to navigate to the 'Manage Addresses' page and click on the Friendly Name of the address you would like to edit.
To update your address through the REST API, you'll need to make a POST request to the addresses instance resource. Our REST API documentation on addresses includes more examples on how you can do this in the programming language of your choice.
Please keep in mind that the IsoCountry of an address cannot be updated. To modify the country of an address, you must create a new address.
