I currently use WooCommerce to run an ecommerce website on WordPress.
I would like to have a shipping plugin that communicates with the Parcel2Go courier booking website API [url removed, login to view]
The plugin would do the following:
Determine the product in cart with largest dimensions (dimensions are set per product already), calculate the total weight of all items in basket. Send the parcel size (largest dimensions + calculated weight) along with user information to the Parcel2Go API which will then return a selection of postage options. Select lowest price and add a set packing fee, so if parcel dimensions larger than X, add £10, £20 etc.. Then the plugin will present the user with price on WooCommerce checkout.
You can view the API documentation here [url removed, login to view]
This is a pretty simple task, I hope I haven't made it sound overly complicated.
Please let me know if you would require any further information.
