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

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

</Note>

Medusa has payment related features available out-of-the-box through the Payment 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 Payment Module.

<Note>

Learn more about why modules are isolated in this documentation.

How to Use the Payment 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.PAYMENT", "Resolve the module in a step."] ]

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

const createPaymentCollectionStep = createStep(
  "create-payment-collection",
  async ({}, { container }) => {
    const paymentModuleService = container.resolve(Modules.PAYMENT)

    const paymentCollection = await paymentModuleService.createPaymentCollections({
      currency_code: "usd",
      amount: 5000,
    })

    return new StepResponse({ paymentCollection }, paymentCollection.id)
  },
  async (paymentCollectionId, { container }) => {
    if (!paymentCollectionId) {
      return
    }
    const paymentModuleService = container.resolve(Modules.PAYMENT)

    await paymentModuleService.deletePaymentCollections([paymentCollectionId])
  }
)

export const createPaymentCollectionWorkflow = createWorkflow(
  "create-payment-collection",
  () => {
    const { paymentCollection } = createPaymentCollectionStep()

    return new WorkflowResponse({
      paymentCollection,
    })
  }
)

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

import type {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"
import { createPaymentCollectionWorkflow } from "../../workflows/create-payment-collection"

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

  res.send(result)
}

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

import {
  type SubscriberConfig,
  type SubscriberArgs,
} from "@medusajs/framework"
import { createPaymentCollectionWorkflow } from "../workflows/create-payment-collection"

export default async function handleUserCreated({
  event: { data },
  container,
}: SubscriberArgs<{ id: string }>) {
  const { result } = await createPaymentCollectionWorkflow(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 { createPaymentCollectionWorkflow } from "../workflows/create-payment-collection"

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

  console.log(result)
}

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

</CodeTab> </CodeTabs>
