TaxEngineAdapter Interface

Retrieves and evaluates the details from a tax engine to define tax details.

You can extend the TaxEngineAdapter interface to define a custom tax adapter based on your requirements. Use the custom tax adapter with Billing services to implement standard tax.

Create a custom object and associated fields to store tax details, such as tax rate for a country. For example, create a custom object named CountryTaxRate with Country_Code and Tax_Rate fields. Create records to define the details for these fields.

Methods

processRequest(requestType) — The processRequest method takes an instance of TaxEngineContext class and returns a response with the calculated tax details through the TaxDetailsResponse class or an error response through the ErrorResponse class.

Tax Mappings for Invoices and Credits
