Framework for customizations

Faster time to market with our framework

Our framework tooling lets you build custom integrations and features in no time. Easily add custom data models, modules, workflows, UI extensions, and API endpoints.

A workflow step performs a query or action in a system. Steps can receive inputs from previous steps and return data to be used in subsequent steps. You can resolve services in your steps, allowing you to build business logic involving Medusa’s core commerce modules, third-party systems, or custom systems.

create-order-in-erp.ts

sync-order-to-erp.ts

src > workflows > steps > create-order-in-erp.ts

import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk"


export const createOrderInERP = createStep(
 "create-order-in-erp"
 async (order: StepInput, { container }) => {
  const erpService = container.resolve("erp")
  
  const createdOrder = await erpService.createOrder(order)


  return new StepResponse(createdOrder)
 }
)

To connect multiple steps together you create a Workflow. Creating a Workflow is like writing any other function. Behind the scenes Medusa generates a representation of your workflow that enables automatic retries of steps if they fail.

create-order-in-erp.ts

sync-order-to-erp.ts

src > workflows > sync-order-to-erp.ts

import { createWorkflow, WorkflowResponse } from "@medusajs/framework/workflows-sdk"
import { createOrderInERP, transformOrder } from "./steps"


export const syncOrderToERP = createWorkflow(
 "sync-order-to-erp",
  (input: WorkflowInput, { container }) => {


  const medusaOrder = retrieveOrder(input.order_id)


  const createdOrder = when({ medusaOrder }, ({ medusaOrder }) => {
    return medusaOrder.status === "completed"
  }).then(() => {  
    const preparedOrder = transformOrder(medusaOrder)
  
    return createOrderInERP(preparedOrder)
  })


  return new WorkflowResponse(createdOrder)
 }
)

If step retries don't succeed, Medusa will rollback previous steps. A rollback will call a step's compensation method, ensuring your data is kept consistent across systems.

create-order-in-erp.ts

sync-order-to-erp.ts

src > workflows > accept-quote.ts

import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk"


export const createOrderInERP = createStep(
 "create-order-in-erp"
 async (order: StepInput, { container }) => {
  const erpService = container.resolve("erp")
  
  const createdOrder = await erpService.createOrder(order)


  return new StepResponse(createdOrder, createdOrder)
 },
 // In the face of errors, we roll back and delete the order
 async (createdOrder, { container }) => {
   const erpService = container.resolve("erp")


   await erpService.deleteOrder(createdOrder)
 } 
)

You can trigger your workflows anywhere in Medusa. Use your workflows in Subscribers to start them in response to an event. Start them in response to requests with API Routes. Or have them run on a defined schedule with Scheduled Jobs.

create-order-in-erp.ts

sync-order-to-erp.ts

src > subscribers > sync-order-to-erp.ts

import {
  type SubscriberConfig,
} from "@medusajs/framework"
import syncOrderToErp from "../workflows/sync-order-to-erp"


export default async function handleOrderPlaced({
  event: { data },
  container,
}) {


  const orderService = container.resolve("order")


  const order = await orderService.retrieve(id)
    
  await syncOrderToErp(container).run({
    input: {
      order
    },
  })
}


export const config: SubscriberConfig = {
  event: "order.placed",
}
