• src/functions.ts:761-769 (handler)

  The core handler function implementing the get_discount_group tool logic. It takes a Paddle instance and validated params, extracts discountGroupId, fetches the discount group via Paddle SDK, and returns it or the error.

  export const getDiscountGroup = async (paddle: Paddle, params: z.infer<typeof Parameters.getDiscountGroupParameters>) => {
    try {
      const { discountGroupId } = params;
      const discountGroup = await paddle.discountGroups.get(discountGroupId);
      return discountGroup;
    } catch (error) {
      return error;
    }
  };
