API integrations & automations.

50+ APIs integrated. Counting.

If your business runs on multiple SaaS tools, you've felt the pain: manually copying data from one platform to another, exporting CSVs, waiting for someone to update a sheet. We solve that by connecting your stack via API — turning multi-platform workflows into single-button automations powered by Google Sheets.

Most APIs are well-documented but poorly understood. The hard parts aren't the request bodies — they're the operational realities: OAuth refresh flows, rate limit backoff, idempotent retries, webhook deduplication, streaming response parsing, partial-failure recovery, and audit-grade logging. That's what we specialize in.

API integration patterns we deliver

• OAuth 2.0 authentication flows — full authorization-code grant with refresh-token rotation, stored securely in PropertiesService
• Webhook receivers — synchronous (instant write to Sheets) or queued (with LockService for concurrency safety)
• Streaming response parsing — concatenated JSON, Server-Sent Events (SSE), chunked responses (used for OpenAI, Julius AI, Anthropic Claude)
• Rate-limit-aware bulk operations — token-bucket awareness, exponential backoff, retry queues
• Idempotency keys for write operations to prevent duplicates during burst traffic or replay attacks
• Background processing via self-chaining time-driven triggers for long-running batch operations
• Comprehensive logging — every API call timestamped with request ID, user, status, and payload

APIs we've integrated

Across 400+ projects we've built integrations with:

Common integration projects

Shopify → Google Sheets order sync

Real-time order capture via webhook with line-item breakdown, customer info, fulfillment status, and tag-based routing. Includes refund/cancellation handling and idempotency keys.

Amazon SP-API multi-region report puller

Scheduled reports for Sales, Inventory, FBA, Settlement, and Returns. NA + EU region support with separate refresh tokens. Auto-converted to local timezone & currency.

OpenAI / Claude streaming chat in Sheets

Custom =AI(prompt) function with streaming response display, conversation history, markdown table rendering, and per-user usage tracking.

Stripe payment dashboard

All Stripe events (charges, subscriptions, refunds, disputes) flowing into Sheets with reconciliation against your invoicing system. Recurring revenue calculations, churn alerts.

Calendar & scheduling automations

Google Calendar event creation from Sheet rows, conflict detection, attendee management, automated email reminders via Gmail. Used for client onboarding, fulfillment scheduling, sales demos.

Our integration approach

1. Read the docs (so you don't have to)

Every API has quirks: weird auth flows, undocumented rate limits, deprecated endpoints, regional variations. We've usually already hit them. If we haven't, we'll build a quick proof-of-concept against your sandbox before quoting the full project.

2. Design for failure

Networks fail. Tokens expire. Rate limits trigger at the worst times. Every integration we ship has retry logic, exponential backoff, idempotency, and audit logging baked in from day one — not bolted on after a production incident.

3. Make it observable

You should be able to answer "what happened with that order yesterday?" in 10 seconds. Every integration writes to a Logs sheet with timestamp, user, request, response status, and payload — so debugging is forensic, not guesswork.

4. Ship the docs alongside the code

Every project comes with a setup guide explaining: where to get API credentials, how to refresh tokens manually if needed, what each trigger does, what to do if a webhook stops firing.

FAQs

Will the integration break when the API changes?

APIs do evolve. Major changes (e.g., Etsy migrating from v2 to v3, Amazon MWS to SP-API) typically have 6+ month deprecation windows. We monitor changelogs for APIs we've integrated and offer maintenance retainers to handle migrations proactively.

Can you handle high-volume webhooks?

Yes. For high-throughput cases (1,000+ events/hour) we use queue-based architectures with deduplication keys, batch processing on time triggers, and dead-letter handling. For very high volume (100K+/day) we sometimes recommend Cloud Functions instead — we'll be honest about when Apps Script is the right tool.

What about rate-limited APIs like Amazon SP-API?

Standard practice. Every Amazon integration we ship has per-endpoint rate-limit tracking, automatic backoff, and queued retry. We've never hit a permanent throttle in production.

Can you integrate with internal/private APIs?

Yes — internal REST APIs, custom GraphQL endpoints, legacy SOAP services, even SFTP-based data exchanges. Send us the docs (or sample curl commands) and we'll quote.
