BigCommerce automation: webhooks, APIs and the workflows worth building first

BigCommerce attracts merchants who want an open, API-first platform without hosting their own software. That design suits automation: almost everything you can do in the control panel can be done through an API, and the platform emits events when things happen. It also means that more is left to you than on a more opinionated platform: there is no single built-in workflow engine, and the quality of an automation depends on the integration you build.

This playbook covers what BigCommerce offers for automation, the workflows that tend to pay back first, the special cases of B2B and multi-storefront, the limits to respect and a rollout plan. It draws on lessons from comparing Shopify and WooCommerce, webhooks and monitoring, which apply here too. Features and limits change, so rely on BigCommerce’s documentation for specifics.

The building blocks

Authentication and access

API access uses credentials created in the control panel or through an app, with scopes limiting what each can do. Grant the minimum scopes a workflow needs. Store tokens in a secure vault or your automation tool’s credentials store, not in documents or code. Keep the account owner’s access under your control, as covered in automation handover documentation. Rotate credentials when people leave and when a vendor relationship ends.

Webhooks: how to use them well

1. Register webhooks for the specific scopes you need, such as orders created, updated or status changed, shipments created and inventory changed.
2. Point them at a stable HTTPS endpoint that you control.
3. Verify that each request is genuine, using the mechanism BigCommerce documents, such as a shared header value or a client secret check.
4. Respond quickly with a success code, then process the event from a queue.
5. Webhook payloads typically carry identifiers and the event type rather than the full resource; fetch the current record through the API before acting.
6. Make processing idempotent, because events can repeat or arrive out of order.
7. Monitor delivery. If your endpoint fails repeatedly, BigCommerce may deactivate the webhook, so alert on silence.

The same principles appear in our guides to idempotency and WooCommerce webhooks. A scheduled reconciliation, comparing recent orders with what your downstream system received, is the safety net.

Workflows worth building first

Rate limits and batching

BigCommerce applies rate limits to API requests, and the limits depend on your plan and the API. Responses typically include headers telling you how many requests remain and when the window resets. Respect them: read the headers, slow down when the budget is low, retry with backoff on rate-limit responses, and use batch endpoints, filters and field selection to reduce calls. Avoid fetching entire catalogues repeatedly; use modified-since filters or webhooks to find changes. The ideas in Shopify API rate limits carry over.

B2B, price lists and customer groups

Many BigCommerce merchants sell to businesses, where prices, catalogues and payment terms differ by customer. Automation can sync company accounts and price lists from an ERP or CRM, route quote requests, apply approval workflows, issue invoices and handle reorders. Complexity rises with each customer group, so keep data in one source of truth and write rules down. Test with real customer scenarios, because B2B errors are expensive and visible to important accounts.

Multi-storefront, headless and marketplaces

• Multi-storefront. One catalogue, several storefronts: automations must know which storefront an order came from, for currency, tax, shipping and messaging.
• Headless. A custom front end calls the APIs; automation hooks into events the same way, but the checkout and messaging may be yours to build.
• Marketplaces and channels. Orders from other channels should flow into the same fulfilment process; see multichannel inventory buffers.
• International. Currencies, taxes and duties need attention in pricing and messages.

Apps or custom: how to decide

BigCommerce’s marketplace has apps for most common needs: shipping and fulfilment tools, ERP and accounting connectors, email and SMS platforms and helpdesk integrations. For standard cases, an app is usually quicker and cheaper than building. Choose custom work when your process is unusual, when you need tighter control over data, when you must connect several systems in one flow or when an app’s pricing scales poorly with your volume. Before installing any app, check what it can read and change, how it handles failures, who supports it and what it costs at ten times your current volume. Keep a list of installed apps and their owners, and remove the ones you no longer use.

Testing environments

Test changes outside the live store where you can. BigCommerce lets you create sandbox stores for development, and you can use draft products, test payment methods and test customer accounts to run orders through a workflow without real money. Build a standard test checklist: a normal order, a discounted order, an order with several shipments, an international order, a cancellation and a refund. Run it after any change to the store or to a workflow. The few hours this takes are cheaper than debugging in front of customers.

Monitoring and documentation

Treat each workflow as a small product. Document its trigger, steps, owner and failure handling. Add error alerts, heartbeats for the order path and a daily reconciliation. Track API errors and rate-limit responses, since a rise often warns of a problem before orders stop. Keep a change log and an export of workflow definitions. Our care plans include this monitoring.

Rollout plan

1. Audit. List manual tasks, volumes and failures; see the 25-question audit.
2. Choose one workflow. The one with the clearest return and lowest risk, often order status updates or inventory alerts.
3. Build in a sandbox. Use a test store or draft products.
4. Pilot. Run alongside the manual process for a week or two.
5. Go live with monitoring. Alerts and a rollback path.
6. Review and expand. Add the next workflow once the first is stable.

A worked example

A BigCommerce store with 1,000 orders a month spends about 12 hours a week on manual order forwarding, tracking updates and stock adjustments. It builds three workflows: order routing with validation, shipment-to-customer messages and a nightly inventory sync with a drift report. After a two-week pilot, manual time falls to about 3 hours a week, saving 36 hours a month, or $790 at $22 an hour. Oversell cancellations drop from around 12 a month to 3, saving about $180. The build cost of roughly 45 hours is recovered in a few months. The figures are illustrative.

Mistakes to avoid

• Ignoring rate limits and getting throttled during sales.
• Processing webhooks synchronously and timing out.
• Trusting payloads without verification or a fresh fetch.
• Over-broad API scopes.
• No reconciliation, so silent losses go unnoticed.
• Customising per storefront by hand, instead of by rule.
