Hey i am able to integrate carrier service i have provided my service rates url and i get the correct request and correct response but i want to be able to pass custom parameter to my carrier service rates url how am i going to be able to do that?
What type of parameters do you want to pass? Data from your shop?
Not sure how to help without some more information.
I have exactly same question, so my shop will have multiple accounts with carrier and i want to send my account code to carrier with shipping request.
how can i do that? Thanks in advance.
