const Moltin = new MoltinClient({

Running sls deploy will deploy the APIGateway and the lambda in this package.

  • Usage Tax are generally calculated at the time the user informs of the shipping location. At this point you can then send the shipping location and the cartId to the APIEndpoint that was created.

This will fetch the tax rate for the users location, then add the amount to the users cart as a custom item and return the amount in the response. This response can then be to the user as the tax amount that will be applied.
