I will integrate apis and connect your business systems


About this gig
Most business systems already hold the data you need. The problem is that they do not talk to each other, so someone ends up copying it by hand.
We connect them properly.
WHAT WE INTEGRATE
Payments: Stripe, PayPal, subscriptions and webhooks
E-commerce and ERP: orders, stock, prices and invoices
CRM and marketing tools, synced in both directions
Custom REST or GraphQL APIs, built or consumed
Legacy systems with no API: files, SFTP, middleware
HOW WE WORK
Step 1: We read the docs, test the endpoints and map the data on both sides
Step 2: We build it with auth, retries, rate limits, idempotency and logging
Step 3: You get the code, the documentation and visibility over what is flowing
Most integrations fail on the edge cases, not the happy path. We plan for the failures first, so a third-party outage never becomes your outage.
Tell me which two systems you want connected and what should sync. You get a scope, a timeline and a fixed price before you order.

FAQ
What if the system I use does not have an API?
We still have options: scheduled file or CSV exchange, SFTP, database access, or a small middleware layer that sits in front of it. Tell me the system and I will confirm what is realistic.
Do I need to share my API keys and credentials?
Only test or sandbox credentials during development, and ideally scoped to the minimum permissions needed. For production we can deploy with your team so the real keys never leave your side.
