I've integrated the Shopify active_shipping gem into my site and I am trying to get negotiated rates from my UPS account (I can get regular rates). I can't find any documentation on the negotiated rates. Can anyone help me out here? I think this line of code should work but it doesn't produce any errors or any different shipping rates.
response = carrier.find_rates(origin, destination, packages, {negotiated_rates: true})
I ran across this link here but still no luck:
