Firstly, here's a couple of things to keep in mind:
The Stitch website name, Zibbet Marketplace shop name and the A.C. Moore Marketplace shop name must match (if you have these sales channels turned on)
When you change your shop name, the URL of your website will change and the old URL will no longer work. This means you'll also need to re-configure your custom domain, if you have this setup.
If you have chosen a name for your website you're not happy with, please follow these steps to change the name...
In your Zibbet Admin, click the Stitch icon on the left-hand navigation. A secondary navigation panel will appear.
Click on "Disconnect".
Type the word "DISCONNECT" into the field and click the red button. This will turn the Stitch sales channel off, and unlist all of your products from this sales channel.
Note: If you also sell on the Zibbet Marketplace and A.C. Moore Marketplace, you will need to repeat this process under the "Zibbet Marketplace" and "A.C. Moore Marketplace" secondary navigation panel.
Once all channels are disconnected (if you sell on all), you can then go to the "Connect Sales Channel" page.
Click to "Connect to Stitch" sales channel button and you'll be presented with a modal, which will allow you to enter a new shop name.
