Shopify + Rebuy implementation checklist (2025)

This section adds practical “make it stable” steps you can use after you install the app/connector. It’s intentionally lightweight: the goal is fewer sync surprises, cleaner reporting, and easier troubleshooting.

1) Quick setup checklist

  • Permissions first: grant only the scopes you need (orders/customers/products as required) and document who owns the admin credentials.
  • Data mapping: confirm how email, phone, currency, and SKU are mapped between Shopify and Rebuy.
  • Historical import: decide how far back to import orders/customers (avoid importing years of data if you don’t need it).
  • Deduplication rules: pick one unique identifier per object (usually email for customers, order ID for orders) to prevent doubles.
  • Alerts: set a lightweight alert path (email/Slack) for failed syncs, auth expiry, and API rate limits.

2) Data you should verify after connecting

Most integration issues show up in the first hour if you test the right things. Use the table below as a QA checklist (create a test order if needed).

Data objectWhat to checkWhy it matters
CustomersEmail/phone format, marketing consent fields, duplicatesPrevents double messaging and broken segmentation
OrdersOrder total, tax, discount, shipping, currencyKeeps revenue reporting and automation triggers accurate
Line itemsSKU, variant ID, quantity, refunds/returns behaviorAvoids inventory and attribution mismatches
FulfillmentStatus changes + timestamps, tracking numbers, carrier fieldsDrives customer notifications and post-purchase flows
CatalogProduct titles, handles, images, collections/tagsEnsures personalization and reporting match your storefront

3) Automation ideas for Marketing

  • Welcome series: new subscriber → educational sequence + first-purchase offer in Rebuy.
  • Abandoned cart: cart started but not purchased → reminder email/SMS from Rebuy (timing based on your AOV).
  • Post-purchase: order created → delivery/usage tips + cross-sell for complementary products in Rebuy.
  • Win-back: no purchase in 60–90 days → reactivation campaign using Rebuy segments.
  • VIP: customer hits LTV threshold → move into VIP tier and trigger perks via Rebuy.

API sanity check (Shopify Admin API)

If your integration UI says “connected” but data isn’t flowing, a quick API call helps confirm whether the store is accessible and returning the objects you expect.

# List the 5 most recent orders (GraphQL)
curl -X POST "https://your-store.myshopify.com/admin/api/2025-01/graphql.json" \
  -H "X-Shopify-Access-Token: $SHOPIFY_ADMIN_TOKEN" \
  -H "Content-Type: application/json" \
  -d "{\"query\":\"{ orders(first: 5, sortKey: CREATED_AT, reverse: true) { edges { node { id name createdAt totalPriceSet { shopMoney { amount currencyCode } } customer { email } } } } }\"}"

Tip: keep tokens/keys in environment variables, and test in a staging store/site before rolling changes to production.

4) KPIs to monitor (so you catch problems early)

  • Sync freshness: how long it takes for a new order/customer event to appear in Rebuy.
  • Error rate: failed syncs per day (and which object types fail most).
  • Duplicates: number of merged/duplicate contacts or orders created by mapping mistakes.
  • Revenue parity: weekly spot-check that Shopify totals match downstream reporting (especially after refunds).
  • Attribution sanity: confirm that key events (purchase, refund, subscription) are tracked consistently.

5) A simple 30-day optimization plan

  1. Week 1: connect + map fields, then validate with 5–10 real orders/customers.
  2. Week 2: enable 1–2 automations and measure baseline KPIs (conversion, AOV, repeat rate).
  3. Week 3: tighten segmentation/rules (exclude recent buyers, add VIP thresholds, handle edge cases).
  4. Week 4: document the setup, create an “owner” checklist, and set a recurring monthly audit.

Common issues (and fast fixes)

Even “simple” integrations fail in predictable ways. Use this as a quick troubleshooting playbook for Shopify + Rebuy.

  • Duplicate customers/orders: usually caused by running two connectors at once. Pick one source of truth and dedupe by email (customers) and order ID (orders).
  • Currency/timezone drift: confirm store timezone and reporting currency match what Rebuy expects, especially if you sell internationally.
  • Missing permissions: if data is partially syncing, re-check API scopes (orders vs customers vs products) and re-authorize the app.
  • Webhooks not firing: look for blocked callbacks, disabled webhooks, or a stale token. If possible, test with a fresh order and watch for events.
  • Rate limits & delays: large imports or high order volume can queue syncs. Stagger imports, reduce lookback windows, and monitor retry queues.
  • Refund/return mismatch: clarify whether refunds create separate objects or adjust the original order record (finance teams should agree on the model).

Privacy & compliance notes (2025)

Integrations often touch personal data (email, phone, address). Keep this lightweight checklist in mind:

  • Least privilege: only grant the data scopes you actively use; remove unused apps quarterly.
  • Consent fields: treat marketing consent separately from transactional messaging (especially for SMS).
  • Data retention: define how long you keep customer event data, and who can export it.
  • Access review: restrict admin accounts and rotate keys/tokens if staff changes.

Suggested rollout plan

  1. Connect in staging (if possible): validate mapping on a small dataset.
  2. Import a short history window: start with 30–90 days unless you have a clear reason to import more.
  3. Run side-by-side QA: compare a handful of orders across systems (totals, taxes, shipping, refunds).
  4. Go live gradually: enable 1–2 automations first, then expand once you trust the data.

Change control (keep it maintainable)

  • One owner: assign a single owner for the integration (who approves mapping and workflow changes).
  • Log changes: track what you changed (fields, filters, timing) and why, so you can roll back quickly.
  • Monthly audit: re-check scopes, API tokens, and error logs—especially after major store/theme/app changes.
