Examples of Pricing Module

In this document, you’ll find common examples of how you can use the Pricing Module in your application.

Create a Price Set

• Next.js App Router
• Medusa API Router

import { NextResponse } from "next/server"

import {
  initialize as initializePricingModule,
} from "@medusajs/pricing"

export async function POST(request: Request) {
  const pricingService = await initializePricingModule()
  const body = await request.json()

  // A rule type with `rule_attribute=region_id` should 
  // already be present in the database
  const priceSet = await pricingService.create([
    {
      rules: [{ rule_attribute: "region_id" }],
      prices: [
        {
          currency_code: body.currency_code,
          amount: body.amount,
          rules: {
            region_id: body.region_id,
          },
        },
      ],
    },
  ])

  return NextResponse.json({ price_set: priceSet })
}

import { 
  MedusaRequest, 
  MedusaResponse
} from "@medusajs/medusa";
import { 
  PricingModuleService
} from "@medusajs/pricing"

export async function POST(
  request: MedusaRequest,
  response: MedusaResponse
): Promise<void> {
  const pricingModuleService: PricingModuleService = 
    request.scope.resolve(
      "pricingModuleService"
    )

  // A rule type with `rule_attribute=region_id` should 
  // already be present in the database
  const priceSet = await pricingModuleService.create([
    {
      rules: [{ rule_attribute: "region_id" }],
      prices: [
        {
          currency_code: request.body.currency_code,
          amount: request.body.amount,
          rules: {
            region_id: request.body.region_id,
