Asset Line Item Validation Callback Class
This callback interface allows you to validate all the asset-based amendments performed for a wallet asset on the cart page.
To add the custom class
Code Sample
The sample callback class performs the following validations to prevent the user from removing funds more than the available balance:
- Discount % should be between 1- 100 %
- Discount amount cannot be more than 100%
- Discount amount cannot be more than the available amount
- Price Override adjustment amount cannot be more than the available balance
- Base Price Override adjustment amount cannot be more than the available balance
Note: This is just a sample callback class. You may change the code
per your requirements.
