Connect two systems through their APIs, at a fixed price

Someone on your team copies data from one tool to another every day, or a no-code zap breaks without telling anyone. The two systems are connected directly through their APIs, with retries, logs and tests, and deployed to your own cloud account.

Pay $1,200 & start

$1,200 fixed price, 5 business days after API docs and test credentials for both systems arrive.

No call needed. Questions go to contact@app369.com; we reply by email, usually within one business day.

This fits when

  • Won deals are retyped as invoices by hand
  • New leads should trigger a text, an email or a task straight away
  • A Zapier or Make flow fails silently or has grown expensive
  • Two systems disagree and nobody knows which one is right

API Integration

Two systems that should talk to each other but don’t. For example, a won deal in your CRM creates a Stripe invoice, or a new lead sends a Twilio text. Built with retries, logs and tests, so it keeps working.

$1,200
fixed price, 5 business days

You get

  • One integration between two systems with documented APIs, covering up to 3 event types
  • Triggered by webhook or on a schedule
  • Retries with backoff, and checks so nothing is created twice
  • Logs, plus an email alert when a sync fails
  • Automated tests against mocked APIs
  • Deployed to your cloud account (Cloud Run, Cloud Functions, Cloudflare Workers or Vercel), with a README
  • One revision round

Not included

  • Bulk migration of historical records
  • User interface work

How it works

  1. Step 1

    Pay and describe the flow

    Name the two systems and what should happen when, then send API docs and test credentials for both.

  2. Step 2

    Build the sync

    Webhook-triggered or scheduled, covering up to 3 event types, with retries and checks so nothing is created twice.

  3. Step 3

    Test

    Automated tests against mocked APIs, then a run against your test accounts.

  4. Step 4

    Deploy and hand over

    Deployed to your Cloud Run, Cloud Functions, Cloudflare Workers or Vercel account, with logs, an email alert on failure and a README.

Questions before you pay

Which systems can you connect?
Any two with documented APIs you have access to, such as Stripe, Twilio, SendGrid, HubSpot, Pipedrive, Airtable, Google Sheets or your own backend.
Who pays for hosting?
It runs in your own cloud account, so you pay its hosting directly. Small integrations usually fit in the free or lowest tiers, but that depends on your volume.
Can you move our old records too?
Bulk migration of historical records is outside this offer and quoted separately.
Do I need a call before I pay?
No. The scope, price and delivery time are on this page, and everything happens in writing. If you want to talk live, calls cost $100 per 15 minutes, paid upfront.
Who owns what you deliver?
You do. The code, videos and files delivered under this offer belong to you once paid.
