As of March 16, 2018, we’ve made changes in the way the value of
handle is treated when creating new Products.
Previously, when creating new Products , if you did not supply a value for the optional
handle, we would auto-generate an api handle for that product based on the name.
Going forward, we will instead set the handle to nil for that Product if it is not specified.
For more information, please see Create A Product in the Product API documentation or the Product Family documentation.
