Shopify needs a publicly reachable HTTPS endpoint that can receive HTTP POST requests; a handler or middleware service must sit between Shopify and the spreadsheet to validate the delivery and write the relevant data to Sheets.
What sits between Shopify and Google Sheets?
The basic flow is Shopify → HTTPS receiver → validation and processing → Google Sheets. Shopify sends a webhook to the receiver, not to the spreadsheet. The receiver handles the request and then appends or updates rows.

- Expose an HTTPS endpoint. Shopify’s HTTPS webhook setup requires an
https://destination. The endpoint must be publicly reachable and accept POST requests. See Shopify’s HTTPS webhook setup documentation. - Handle the POST. The receiver reads and processes Shopify’s JSON payload. Shopify describes the delivery payload and headers in its webhook delivery structure documentation.
- Validate the sender. Verify Shopify’s signature against the raw request body before trusting or storing the data.
- Record the event and respond quickly. Save or queue the delivery, acknowledge it successfully, and perform slower spreadsheet work without holding up the response where possible.
- Write to Sheets. Extract only the fields you need and append or update rows in the spreadsheet, with suitable permissions and error handling.
Shopify’s webhook overview explains the subscription and delivery model. Which delivery methods are available depends on the particular app and setup.
Can Google Apps Script be the receiver?
Apps Script can be part of a lightweight integration. A deployed Apps Script web app can route POST requests to a doPost(e) function. Its documented event object exposes the request body as e.postData.contents and the content type as e.postData.type. The handler can parse the body and use Google services to write to a sheet, subject to deployment identity, authorization, permissions, and Apps Script execution constraints. Google documents the web app model in its Apps Script web apps guide.
There is an important security gap to resolve before using a bare Apps Script URL for live Shopify deliveries. Shopify requires signature verification using the incoming X-Shopify-Hmac-Sha256 header and the raw request body. The reviewed Apps Script web app reference documents POST body fields but does not document access to incoming request headers. That documentation therefore does not establish that a bare Apps Script endpoint can read the header needed for Shopify’s required verification.
Shopify’s verification guidance says each HTTPS delivery includes a base64-encoded HMAC-SHA256 signature in X-Shopify-Hmac-Sha256, generated with the app’s client secret and the raw request body. Confirm that your receiver can access the required header and verify the signature before relying on it. If it cannot, put a header-capable receiver or middleware service in front of Sheets.
Why does verification and a fast response matter?
A webhook URL is an internet-facing entry point. HMAC validation lets the receiver check that the delivery was generated by Shopify and that its body matches the signed content. Do not treat a request as trustworthy merely because it arrived at an obscure URL.

Shopify’s current delivery guidance sets a one-second connection timeout and a five-second overall request timeout. It expects a response in the 200 range. A receiver that spends too long waiting on spreadsheet authorization or row writes can fail to respond in time. A safer design validates the request, records it durably or queues it, and acknowledges promptly; later work can update the sheet.
Shopify says it retries failed deliveries up to eight times over four hours. Repeated failures can lead to webhook subscription removal, so check delivery errors and plan how to detect and reconcile missed events. These are Shopify’s stated delivery parameters, not independent performance measurements; see its delivery verification documentation.
How should you handle duplicate or out-of-order deliveries?
Retries mean the same event can arrive more than once, and Shopify does not guarantee that events arrive in the order they occurred. A sheet integration should not assume every POST represents a new event or that the last row received is the latest state.
- Store a stable delivery or event identifier and use it to prevent processing the same delivery twice.
- Use event timestamps or the entity’s current state when deciding whether an update should replace an existing row.
- Make row updates idempotent: processing the same event again should not create unintended duplicate records or reverse newer data.
- Keep a way to review failures and reconcile gaps rather than treating a successful response as proof that every spreadsheet write completed.
Shopify’s guidance on webhook verification and duplicate handling and its webhook overview cover retries and event ordering.

Best Value
| Approach | When it may fit | What to confirm |
|---|---|---|
| Apps Script web app | A small, lightweight flow where Apps Script can receive the POST and write selected data to Sheets. | Confirm access to incoming headers and raw-body HMAC verification, response speed, execution limits, authorization behavior, and how failures are surfaced. Google’s web app guide documents the POST event fields; it does not establish the required header access. |
| Dedicated or serverless HTTPS receiver | You need control over request validation, quick acknowledgment, asynchronous work, and recovery. | Check that it can verify Shopify’s HMAC from the raw body, persist or queue deliveries, deduplicate events, expose failures, and support reconciliation. |
| Managed automation or messaging service | You want less custom infrastructure and the service supports the relevant Shopify delivery and Google Sheets actions. | Verify signature handling, retry and dead-letter visibility, deduplication, volume limits, cost, and recovery controls. Do not assume these capabilities from a service’s ability to connect Shopify and Sheets. |
Shopify also documents Amazon EventBridge and Google Cloud Pub/Sub as delivery options for supported subscriptions. Availability depends on the app and merchant configuration; neither option removes the need to consider validation, processing, and delivery recovery. See Shopify’s webhook documentation.
What should you check before going live?
- The configured destination is an HTTPS endpoint that accepts Shopify’s POST request.
- The receiver can verify the HMAC using the correct app secret and the unmodified raw request body.
- It responds in time with a successful 200-range status after safely recording or queuing the delivery.
- Duplicate deliveries cannot create duplicate or stale spreadsheet data.
- Spreadsheet authorization and write failures are visible and recoverable.
- You have monitoring for failed deliveries and a plan to reconcile missing events.
