We ship predominantly lithium ion batteries with USPS/stamps.com using shipstation. For these we need to check the "This shipment contains dangerous goods" checkbox under other shipping options.
I can't seem to find a way to automate clicking this checkbox, but this would be a very important feature for us. I checked automation rules and can't find it as an option, there is only specific ones for dry ice and alcohol. And I checked shipping presets, and other shipping options aren't a part of those. Am I missing anything?
If it is impossible, is there some way that this could be done using the API if I engaged a developer?
Thanks for any help.
