How do I use the Shipping API (Custom Shipping Service) module?

3dcart's Shipping API module allows merchants to connect their store to an independent shipping service and get real-time shipping rates from the service. To use the module, you would need to contact your shipping service and ask them to provide you with the following:

  • An endpoint URL
    The URL for your shipping service that the 3dcart store will send the order information to*.
  • Access User/Password
    Login credentials needed to connect to the endpoint URL.

*Endpoint URL
As mentioned, the Endpoint URL is the URL for your shipping service that the 3dcart store will send order information to, and get shipping rates from. The following is an example of the process you can share with your shipping service so they can provide you with the necessary set up.

At the time of checkout, the Shipping API module will send a request to the endpoint URL in JSON format. The information sent will include the shipping origin address, the destination shipping address, the line items in the cart including SKU, Name, Price, Weight, and Dimensions. The JSON request from the 3dcart store will look like this example:

{
	"orderid": 38,
	"weightunit": "LBS",
	"measurementunit": "IN",
	"totalitems": 1,
	"totalweight": 1,
	"orderamount": 3.99,
	"shippingfrom": {
		"state": "UT",
		"postalcode": "84101",
		"country": "US"
	},
	"shippingto": {
		"address1": "123 Street",
		"address2": "",
		"city": "Coral Springs",
		"state": "FL",
		"postalcode": "33065",
		"country": "US"
	},
	"items": [{
		"sku": "SAMPLE-1007",
		"name": "[DEMO] Extreme Pak Neon Pink Leopard Print Shopping Tote",
		"quantity": 1,
		"unitprice": 3.99,
		"unitweight": 1,
		"unitlength": 0,
		"unitwidth": 0,
		"unitheight": 0
	}]
}

After the JSON request is sent, the store will then expect a JSON response from your shipping carrier to display their rates for the shopper to select. The expected JSON response will need to look like this for the rates to display:

{"shippingmethods":
[
    {"methodname":"DHL Priority", "rate":32.00},
    {"methodname":"USPS First Class", "rate":3.00},
	{"methodname":"UPS Ground", "rate":12.00}
]}

During the checkout process, the rates will be retrieved from your independent shipping service and will be displayed for the shopper to select and complete their order.
