API Integrations

Connect your systems to the world
Many business systems don't talk to each other. I specialize in building the bridges — connecting your tools to government systems, payment providers, CRMs, and third-party APIs.

Who is it for

  • ✓
    Businesses that need to report to government agencies
  • ✓
    Companies wanting to connect internal systems to external providers
  • ✓
    Startups needing integration with local infrastructure

How it works

1

Requirements analysis

Understand which systems need connecting and what formats are required.
2

Build the integration

Develop the connection, handle authentication, formats, and error handling.
3

Test and deploy

Test with real data, deploy to production, and ensure stability.

Examples

Connect to government and regulatory systems
Integrate with payment providers
Connect to ERP and management systems
Process multilingual forms and documents

Let's talk about how this can work for your business.

API integrations are the plumbing of a modern business — the quiet connections that let your CRM, accounting system, website, WhatsApp line, warehouse and ads platform share the same data instead of asking someone to copy-paste between them. Done right, integrations remove 5–20 hours of manual work per week and eliminate the errors that come from somebody mistyping a number at 5pm on a Friday. Done wrong, they turn into a pile of fragile scripts that break every time a vendor ships an update. This page explains how we design integrations that keep working after launch, which platforms we connect most often, and what a typical API integration project actually costs.

The integrations we build most often

Most of our integration work connects three pairs of systems: CRM to accounting (lead closes in HubSpot → invoice generated in Xero → payment status back into HubSpot), e-commerce to fulfilment (Shopify order → warehouse API → tracking link pushed to WhatsApp), and messaging to internal tools (WhatsApp message → Zendesk ticket → lead record in Pipedrive). We also connect newer AI services — OpenAI, Anthropic, ElevenLabs, Whisper — to production systems so an AI agent can actually write back into the CRM or update an order status instead of just drafting text.

Why we prefer a real integration over a no-code shortcut

Drag-and-drop tools like Zapier and Make are fine for five-step flows, but they break the moment you need to transform data, handle errors gracefully, or retry a failed webhook. Our integrations are typically written as small TypeScript or Python services, deployed to Vercel, AWS Lambda or Cloud Run, with proper logging, automatic retries with exponential backoff, and a clear dead-letter queue for the edge cases a human needs to look at. That means when a vendor has an outage, the integration doesn't silently lose your orders — it queues them and fires them once the service comes back.

Handling authentication, rate limits and schema changes

Real API integration work is 20% happy-path and 80% edge cases. We design every integration with rotating OAuth tokens stored in a secrets manager, per-endpoint rate-limit awareness so we don't get banned by an aggressive API, and schema validation that catches it when a vendor quietly renames a field. Each integration ships with an integration test suite that runs against a sandbox or mocked API on every deploy, so you don't discover the Salesforce SDK broke your flow three days after it broke.

Operating integrations after launch

The failure mode of most integrations isn't that they were poorly built — it's that nobody notices when they stop working. Every integration we ship writes structured logs, pings a monitoring channel on every error, and exposes a simple health endpoint. We also document the manual fallback — exactly what someone does if the integration is down for an hour — so the business keeps running. About a third of our integration clients keep us on a small monthly retainer for upgrades when vendors change their API; the rest take full ownership and only call us when a new connection needs to be built.

API integrations — frequently asked questions

Which systems do you most commonly integrate?
We routinely connect HubSpot, Salesforce, Pipedrive, Monday, Zoho, QuickBooks, Xero, Priority, Hashavshevet, Shopify, WooCommerce, Zendesk, Freshdesk, Intercom, WhatsApp Business Cloud API, Telegram, Slack, Google Workspace, Microsoft 365, Meta Ads, Google Ads, Mailchimp, Twilio, Stripe, and dozens of custom internal APIs. If a system has a documented API, we've probably built against it or can do so in a few days.
How long does a typical API integration take?
A focused single-flow integration (for example, sending every new Shopify order into QuickBooks with tax breakdowns) usually takes 3–7 working days end-to-end. Bi-directional sync between two systems with conflict handling and history backfill is typically 2–4 weeks. We always scope during discovery so you see a written quote before we start building.
Can you integrate with a system that doesn't have a public API?
Yes — we do this a lot. Older ERPs, custom in-house systems and some government portals have no public API. For those we use scheduled database exports, direct database connections, email parsing, or RPA (robotic process automation) that drives a browser the way a human would. It's less elegant than a clean API but perfectly reliable when it's built carefully.
How do you handle failures when a vendor's API goes down?
Every integration we build uses a queue-and-retry pattern. When a downstream API returns an error, the message is kept in a queue with exponential-backoff retries, and after a configurable number of failures it lands in a dead-letter queue that pings an operator. Nothing gets silently dropped, and once the vendor comes back the integration drains the queue automatically.
What does it cost to run an integration long-term?
Hosting cost for a typical integration runs between $5 and $40 per month on Vercel, AWS Lambda or Cloud Run — a few cents per invocation and a tiny database line. The meaningful cost is maintenance when a vendor changes their API, which happens once or twice a year per major integration. We quote an optional retainer for that or document the code clearly enough that your team can handle it.
Do you own our data or API keys?
No. All code is deployed into your own cloud account or into a repo that you own, and all API keys live in a secrets manager that you control. We ask for temporary access only during the build, and the whole integration continues to run if we stop working together.

If you have two systems your team copies data between every week, or a process where an error in one tool silently breaks a report in another, that's almost always worth an integration. The fastest way to scope it is a 30-minute call where we look at both systems' APIs together and tell you what a clean integration would actually cost.
