Hello, I am integrating with the Carrier Service and I was wondering if there was a way of offerring levels of services inside that Carrier we created. For example If I create the Carrier I want with the same carrier to offer the option of shipments express or normal. Is there any way of doing that or I have to create a new carrier for every level of service I want to offer to the clients?
If you're creating a CarrierService integration, your carrier can respond with multiple shipping rates for any request, so you can use a single carrier to return multiple rates at checkout. Our CarrierService documentation shows an example that includes 3 rates in the response (click "View Response" at the bottom of the first example).
