In this section of the documentation, you will find resources to learn more about the Promotion Module and how to use it in your application.

Refer to the Medusa Admin User Guide to learn how to manage promotions using the dashboard.

</Note>

Medusa has promotion related features available out-of-the-box through the Promotion Module. A module is a standalone package that provides features for a single domain. Each of Medusa's commerce features are placed in Commerce Modules, such as this Promotion Module.

Promotion Features

Discount Functionalities: A promotion discounts an amount or percentage of a cart's items, shipping methods, or the entire order.
Flexible Promotion Rules: A promotion has rules that restricts when the promotion is applied.
Campaign Management: A campaign combines promotions under the same conditions, such as start and end dates, and budget configurations.
Apply Promotion on Carts and Orders: Apply promotions on carts and orders to discount items, shipping methods, or the entire order.

How to Use the Promotion Module

In your Medusa application, you build flows around Commerce Modules. A flow is built as a Workflow, which is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism.

You can build custom workflows and steps. You can also re-use Medusa's workflows and steps, which are provided by the @medusajs/medusa/core-flows package.

For example:

export const highlights = [ ["12", "Modules.PROMOTION", "Resolve the module in a step."] ]

import { 
  createWorkflow, 
  WorkflowResponse,
  createStep,
  StepResponse,
} from "@medusajs/framework/workflows-sdk"
import { Modules } from "@medusajs/framework/utils"

const createPromotionStep = createStep(
  "create-promotion",
  async ({}, { container }) => {
    const promotionModuleService = container.resolve(Modules.PROMOTION)

    const promotion = await promotionModuleService.createPromotions({
      code: "10%OFF",
      type: "standard",
      application_method: {
        type: "percentage",
        target_type: "order",
        value: 10,
        currency_code: "usd",
      },
    })

    return new StepResponse({ promotion }, promotion.id)
  },
  async (promotionId, { container }) => {
    if (!promotionId) {
      return
    }
    const promotionModuleService = container.resolve(Modules.PROMOTION)

    await promotionModuleService.deletePromotions(promotionId)
  }
)

export const createPromotionWorkflow = createWorkflow(
  "create-promotion",
  () => {
    const { promotion } = createPromotionStep()

    return new WorkflowResponse({
      promotion,
    })
  }
)

You can then execute the workflow in your custom API routes, scheduled jobs, or subscribers:

import type {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"
import { createPromotionWorkflow } from "../../workflows/create-cart"

export async function GET(
  req: MedusaRequest,
  res: MedusaResponse
) {
  const { result } = await createPromotionWorkflow(req.scope)
    .run()

  res.send(result)
}

</CodeTab> <CodeTab label="Subscriber" value="subscriber">

import {
  type SubscriberConfig,
  type SubscriberArgs,
} from "@medusajs/framework"
import { createPromotionWorkflow } from "../workflows/create-cart"

export default async function handleUserCreated({
  event: { data },
  container,
}: SubscriberArgs<{ id: string }>) {
  const { result } = await createPromotionWorkflow(container)
    .run()

  console.log(result)
}

export const config: SubscriberConfig = {
  event: "user.created",
}

</CodeTab> <CodeTab label="Scheduled Job" value="scheduled-job">

import { MedusaContainer } from "@medusajs/framework/types"
import { createPromotionWorkflow } from "../workflows/create-cart"

export default async function myCustomJob(
  container: MedusaContainer
) {
  const { result } = await createPromotionWorkflow(container)
    .run()

  console.log(result)
}

export const config = {
  name: "run-once-a-day",
  schedule: `0 0 * * *`,
}

</CodeTab> </CodeTabs>
