I had some customization on Shipping page of checkout on Magento2, now I want to send out some data back to my module by the user hitting "Next" button and add to the current cart, so in which way should I do this?

When you progress from the 'Shipping' step to the 'Review & Payment' step, an API request is sent to this function \Magento\Checkout\Model\ShippingInformationManagement::saveAddressInformation. You can view the js that sends the request here `Magento\Checkout\view\frontend\web\js\model\shipping-save-processor\default.js'

To send data to your module you can write a plugin for the saveAddressInformation method. For more information on how to write a plugin, see this documentation page:


  • one question, I tried to alert out the url of the post request in the above mentioned default.js file(which is resourceUrlManager.getUrlForSetShippingInformation(quote)) and got rest/default/V1/carts/mine/shipping-information. Could you explain its meaning?

    If you look in Magento/Checkout/etc/webapi.xml you will see several routes. The url you got in your alert points to the shipping-information route which defines which service will receive the payload. You can read more about the webapi.xml configuration file here devdocs.magento.com/guides/v2.0/extension-dev-guide/… Jan 12, 2016 at 16:44
  • Million thanks, I will try this out and tell you if this works :)

  1. Make a module
  2. Use an obsever on the right event
  3. Implement your code for the observer to make the changes you wish

See for more details: https://firebearstudio.com/blog/magento-2-observers.html

Here is al list of events: http://cyrillschumacher.com/magento2-list-of-all-dispatched-events/

I think you are looking for checkout_cart_product_add_after but I am not sure depending on your explanation.
