Zapier | Google Sheets ↔ Stripe + Webflow Automation

Built a Zapier‑based system that lets the client manage Stripe payments and Webflow CMS directly from Google Sheets. A bidirectional sync keeps Sheets, Stripe, and Webflow perfectly aligned, removing manual entry and reducing errors.

Two‑Way Sync: Changes in Sheets update Stripe customers, payments, and Webflow CMS items—and platform updates flow back to Sheets.

Payments Automation: Create/update customers, invoices, subscriptions, and refunds from simple row edits.

Webflow CMS Control: Add, update, publish/unpublish items from structured Sheet tabs.

Data Validation & Mapping: Field normalization, required‑column checks, and ID lookups to prevent mismatches.

Alerts & Logging: Slack/email notifications on failures; append run logs and error reasons to a “Status” column.

Idempotent Writes: Upsert logic with dedupe keys to avoid duplicates on retries.

Automation: Zapier (multi‑step Zaps, Paths, Webhooks, Code by Zapier)

Payments: Stripe API (Customers, Invoices, Subscriptions, Refunds)

CMS: Webflow API (Collections, Items, Publish)

Data Layer: Google Sheets (structured tabs, protected ranges)

Notifications: Slack/Email for run status

Sheet Edit Trigger: Row add/update detected in specific tabs.

Validate & Enrich: Check required fields; fetch Stripe/Webflow IDs; map to schemas.

Stripe Action: Create/update customer, charge/invoice/subscription, or process refund.

Webflow Action: Create/update CMS item; publish if flagged.

Sync Back: Write resulting IDs, URLs, and statuses to Sheets; update mirrors when Stripe/Webflow change.

Notify & Log: Post success/failure; store timestamps and error messages for audit.

Race Conditions: Added queueing and dedupe keys; used Step Delays and conditional Paths.

API Limits: Implemented batching and exponential backoff with Webhooks/Code steps.

Data Consistency: Centralized ID mapping and enforced required fields via protected ranges and validation.

Zero manual re‑entry between finance, CMS, and tracking sheets.

Fewer errors and faster updates across platforms.

Single source of truth in Sheets with live statuses and links.

Deliver a robust, low‑code automation that lets non‑technical users run Stripe billing and Webflow content entirely from Google Sheets—reliable, auditable, and fast.
