EasyPost allows businesses to integrate tracking statuses, address verification, label purchasing, rating, and more from DHL Global Mail, FedEx, UPS, USPS, and other regional carriers into their site or application and now we have integrated it with the Webkul’s marketplace. EasyPost works as a mediator wherein you can save your various carrier specific credentials with them and you get a key that you can set up in the admin back-end. Now, when ever you ship your products the shipping cost is automatically calculated according to the selected shipping method by the customers.
