Quickstart: Connect to BigCommerce 

This guide will show you how to set up a BigCommerce connection, subscribe to BigCommerce webhooks, and store the webhook data in a Gadget database.

Prerequisites 

Before starting, you will need:

Step 1: Create a new Gadget app 

First, create a new Gadget app and connect it to BigCommerce.

  1. Create a new Gadget app (https://gadget.new), select the BigCommerce app type, and enter a domain name
  2. Click the Connect to BigCommerce button on your app's Home page OR navigate to Settings → Plugins → BigCommerce

Step 2: Create a BigCommerce app, set callback URLs, and select scopes 

Now create a BigCommerce app and connect it to the Gadget app.

  1. Create a new app in the BigCommerce Developer Portal and name your app
  2. Copy the Auth callback URL, and Load callback URL from Gadget to your BigCommerce app
  3. Select the Products Read-only OAuth scope and click Update & Close in the BigCommerce app

Step 3: Set up client credentials and install on a sandbox store 

Finish connection setup by copying the client credentials from BigCommerce back to Gadget and installing the app on a sandbox store.

  1. Click View Client ID for your new app in BigCommerce and copy the Client ID and Client Secret to Gadget, then click Continue
  2. In your BigCommerce sandbox store, navigate to Apps → My Draft Apps, hover over your newly added app, and click Learn more
  3. Click Install

Congrats, you have successfully installed your app on a BigCommerce sandbox store!

The frontend you see is your Gadget app's React frontend built with the BigDesign library and embedded in the sandbox store.

You will also have a new data model at api/models/bigcommerce/store that holds data for the BigCommerce sandbox you installed your app on.

Connection complete!

Gadget takes care of the boilerplate that goes into setting up full-stack BigCommerce apps. By setting up the connection, you have done the following:

  • set up a full-stack application
  • handled BigCommerce OAuth and callbacks for a single-click app
  • created a bigcommerce/store data model and saved the store data
  • taken care of frontend session management with the session model
  • installed the BigDesign library for your React frontend

Step 4: Subscribe to BigCommerce webhooks 

BigCommerce webhooks are available as triggers on global actions.

To subscribe to BigCommerce webhooks:

  1. Navigate to /api/actions in Gadget, click +, and create a new action named handleProductCreate.js
  2. Click + in the Triggers card in your action and select BigCommerce
  3. Select the store/product/created webhook scope used to trigger the action

The action will now be run when the webhook is triggered.

BigCommerce webhook payloads only include the id of the resource that triggered the webhook. To fetch the full resource data, you can use the included BigCommerce API client to fetch the resource data in the action.

  1. Copy-paste the following code into the action file:
/api/actions/handleProductCreate.js
JavaScript
1import { HandleProductCreateGlobalActionContext } from "gadget-server";
2
3/**
4 * @param { HandleProductCreateGlobalActionContext } context
5 */
6export async function run({ params, logger, api, connections }) {
7 // get the BigCommerce API client for the current store
8 const bigcommerce = connections.bigcommerce.current;
9 // fetch the product data
10 const product = await bigcommerce.v3.get("/catalog/products/{product_id}", {
11 path: {
12 product_id: params.id,
13 },
14 });
15 // log the product data and webhook payload
16 logger.info({ product, params }, "product data and webhook payload");
17}
18
19export const options = {
20 triggers: {
21 bigcommerce: {
22 webhooks: ["store/product/created"],
23 },
24 },
25};
  1. To test the webhook, create a new product in your BigCommerce sandbox store.

You should see the product data logged in the Gadget Logs.

To learn more about subscribing to BigCommerce webhooks, see the webhooks guide.

Step 5: Save the BigCommerce webhook payload 

Now you can store that BigCommerce product data in your database so you can use it in your app.

  1. Right click on api/models/bigcommerce, select Add model, and create a new product model
  2. Navigate to api/models/bigcommerce/product/schema and add fields to the model with the following validations:
Field nameField typeValidations
bigcommerceIdnumberUniqueness, Required
namestringRequired
storebelongs to

Note: The store field is a belongs to relationship to the bigcommerce/store model. This is used to associate the product with the store it was created in. The inverse of the relationship should be a has many so that bigcommerce/store has many bigcommerce/product.

You can add more fields as needed, or remove fields you don't need! It is a good idea to only store the data required to power your app.

  1. Update api/actions/handleProductCreate.js to save the product data to the database:
/api/actions/handleProductCreate.js
JavaScript
1import { HandleProductCreateGlobalActionContext } from "gadget-server";
2
3/**
4 * @param { HandleProductCreateGlobalActionContext } context
5 */
6export async function run({ params, logger, api, connections }) {
7 // get the BigCommerce API client for the current store
8 const bigcommerce = connections.bigcommerce.current;
9 // fetch the product data
10 const product = await bigcommerce.v3.get("/catalog/products/{product_id}", {
11 path: {
12 product_id: params.id,
13 },
14 });
15 // log the product data and webhook payload
16 logger.info({ product, params }, "product data and webhook payload");
17
18 // store product data in the product data model
19 await api.bigcommerce.product.create({
20 bigcommerceId: product.id,
21 name: product.name,
22 store: {
23 // get the bigcommerce/store id for the record stored in Gadget
24 _link: connections.bigcommerce.currentStoreId,
25 },
26 });
27}
28
29export const options = {
30 triggers: {
31 bigcommerce: {
32 webhooks: ["store/product/created"],
33 },
34 },
35};
  1. Create another product in your BigCommerce sandbox store and open api/models/bigcommerce/product/data to see your saved product data

Every time you add a product to your BigCommerce sandbox store, the product data will be also saved to your Gadget database!
