IActionCallback2 class provides a mechanism to apply custom actions on cart finalization, submission for approval using the below Web Services.

• ActionInvokerWebService.invokeAfterFinalizeCart
• ActionInvokerWebService.invokeSyncCart
• ActionInvokerWebService.invokeSyncCartAsync
• ActionInvokerWebService.invokeFinalizeCart
• ActionInvokerWebService.invokeFinalizeCartAsync
• ActionInvokerWebService.invokeAfterSyncCart
• ActionInvokerWebService.invokeAfterSyncCartAsync
• ActionInvokerWebService.invokeAfterFinalizeCartAsync
• ActionInvokerWebService.invokeSubmitApproval
• ActionInvokerWebService.invokeGenerateDoc

Action callback executes the custom logic from Web Services on the following aspects of CPQ: ​

• Finalizing the cart
• Synchronizing the cart
• Submitting the cart for approval
• Generating documents

The following methods are available in the Apttus_Config2.CustomClass.IActionCallback2 interface:

The following table lists the response parameters of the Apttus_Config2.CustomClass.IActionParamsCallback.

Example

The sample code below enables you to send out the status of the cart to the proposal owner as callback action after finalizing the cart. You can perform post-finalization by calling the Web Service Apttus_Config2. ActionInvokerWebService.invokeAfterFinalizeCart() passing the custom callback class name and the cart ID as parameters.

global with sharing class Apttus_ActionCallback implements Apttus_Config2.CustomClass.IActionCallback2
{
    global static Boolean finalizeCart(ID cartId) 
	{
		// callback logic to finalize the cart.  This logic will be executed when we call the webservice Apttus_Config2.ActionInvokerWebService.invokeFinalizeCart
        return true;
    }

    global static Boolean afterFinalizeCart(ID cartId)
	{
        // get the owner of the proposal
        Apttus_Config2__ProductConfiguration__c proposalSO = [SELECT Name,Apttus_Config2__Proposald__r.owner.id
