A Medusa plugin giving the power of webhooks to your Medusa store. Receive notifications on discord, slack or anywhere where webhooks can be consumed on events on from your store.

Features

• A helper function to send webhooks from your custom code
• A webhook for order-related events
• Ability to assign custom webhook urls to every event

Setting up the Medusa Webhooks Plugin

Prerequisites

• A Medusa server (Quickstart Guide)
• Redis setup on your Medusa server (Configuring Redis on your Medusa server)
• A webhook endpoint to which you can post webhooks (for testing purposes, I recommend using Svix Play)

Install and Setup the Webhooks Plugin

To install the plugin using NPM, run the following command in your Medusa server directory:

npm install medusa-plugin-webhooks

If you prefer using Yarn, run the following command in your Medusa server directory:

yarn add medusa-plugin-webhooks

Once the plugin is installed, we need to add it to the plugins array in the medusa-config.js file in your Medusa server directory:

const plugins = [
  ...{
    resolve: "medusa-plugin-webhooks",
    options: {
      webhook_url: "https://mystore.com/events", // REQUIRED: CHANGE THIS TO A VALID WEBHOOK ENDPOINT
      webhook_headers: {
        "x-api-key": "supersecretapikey", // You can add custom headers (for example, for authentication)
      },
      webhook_config: {
        "order.placed": {
          enabled: true,
          overrideUrl: "https://mystore.com/events/order-placed", // You can override the URL on a per-event basis,
          overrideHeaders: {
            "x-api-key": "supersecretorderplacedapikey", // You can override the headers on a per-event basis
          },
        },
      },
    },
  },
];

Currently these 4 events are supported:

• order.placed
• order.updated
• order.completed
• order.canceled

By default, notifications for all events are disabled. To enable notifications for any of the above events, set the enabled property to true in the webhook_config object. (see example above)

You can override the URL or headers for any of the above events by setting the overrideUrl or overrideHeaders properties in the webhook_config object. (see example above)

Sending a webhook event from your custom code

You can post a webhook from your code by resolving the webhooks service and then using the postWebhook function. For example:

const webhooksService = scope.resolve("webhooksService");
await webhooksService.postWebhook(
  {
    event: "order.placed",
    data: {
      order_id: "order_id",
      customer_id: "customer_id",
      total_price: 1000,
      currency_code: "USD",
      metadata: {},
    },
  },
  "mystore.com/events/custom", // You can pass in an URL override here as well
  {
    "x-api-key": "customeventsapikey", // You can pass in custom headers here as well
  }
);
