I will do shopify api integration stripe api amazon api ebay api payment api developer


About this gig
Hi there! I build and fix these connections for a living - Shopify, Stripe, Amazon SP-API, eBay, and custom payment/API work. One clean source of truth pushing data everywhere, not five spreadsheets and a prayer.
What you get:
A real connection between the platforms you use, not a generic template
Proper error handling so one failed sync doesn't cost an order
Payments that don't sit in test mode while customers get declined
A plain-English breakdown of what was wrong and what changed
I've fixed integrations other devs gave up on, built new ones from scratch. If support keeps sending you in circles, send your setup - I'll tell you what's going on first.

FAQ
I already have an integration but it's broken, do you fix existing setups, or only build new ones?
Both. Most of my orders are actually fixes, broken syncs, duplicate orders, payments stuck in test mode. Send me access and I'll diagnose it before touching anything.
Which platforms can you actually connect together?
Any combination of Shopify, Stripe, Amazon SP-API, and eBay, plus most third-party payment or shipping APIs. If it has a documented API, I can usually work with it.
I'm not technical — can I still order this without knowing what's "broken"?
Yes. Just describe what's happening (wrong stock numbers, failed payments, orders not coming through) and I'll figure out the technical cause myself.
How do you handle my API keys and store credentials?
You only ever share them through Shopify's staff account access or platform-native API key generation — never in plain chat. Keys are used strictly for the task and not stored after delivery.
What happens if the integration breaks again after you deliver?
You get a revision window included, and I document exactly what was changed so any future developer (or you) can see the setup clearly. I also flag anything likely to need monitoring.
