before-open-checkout

This function is triggered before opening the checkout page.

Description​

It can be used to modify the checkout page before it is opened. For example, you can use this function to redirect the user to a different page rather than the default checkout page.

Usage​

appmakerFunctions.registerAppmakerFn({
  trigger: 'before-open-checkout',
  namespace: 'namespace',
  function: myFunctionHook,
});

Parameters​

You get the following parameters in the function hook:

  • currentCart - The cart object.
  • accessToken - The access token of the user.

Return​

The function should return the modified parameters.

Example​

Below is the sample code to intercept and return a custom url for appmaker checkout:

import appmakerFunctions from '@appmaker-xyz/core';

appmakerFunctions.registerAppmakerFn({
  trigger: 'before-open-checkout',
  namespace: 'namespace',
  function: myFunctionHook,
});

function myFunctionHook({currentCart,accessToken}) {
    return {       
        webUrl: 'https://appmaker.xyz',
    } 
}

The above code will redirect the user to the url https://appmaker.xyz when the checkout page is opened.

To manage the cart on App we use GraphQL Storefront checkout API. Sample cart JSON is available here.
