I will connect fix or integrate any rest API into your app or website
Maksym
About this gig
Struggling with an API that won't connect, keeps erroring, or doesn't behave like the docs promised? I help developers and businesses integrate, fix, and debug REST APIs quickly and reliably.
Connect payment gateways (Stripe, PayPal), pull data from third-party services, set up webhooks, or fix broken authentication (OAuth, API keys, tokens).
What I do:
- Integrate any REST API into your app or script
- Fix broken API calls: auth errors, malformed requests, timeouts, bad response parsing
- Set up webhooks and event-driven integrations
- Handle rate limiting, retries, and error handling
- Write clean, documented, production-ready code
Works with Python (requests, FastAPI, Flask, Django), JavaScript/TypeScript (Node.js, Express, Axios), and major providers (Stripe, Twilio, SendGrid, Shopify, Google, AWS, OpenAI).
Scope protection: Each package covers a defined amount of work. Bigger projects get a clear custom quote first - no scope creep.
Message me with the API and issue, and I'll tell you exactly how I can help.

FAQ
Do you work with any API or platform?
Most REST APIs, yes - Stripe, PayPal, Twilio, SendGrid, Shopify, Google, AWS, OpenAI, and custom/internal APIs. Message me with the specific API and I'll confirm before you order.
What do you need from me to get started?
API documentation (or a link to it), any existing credentials/API keys (never share passwords), and a clear description of what you want the integration to do or what error you're hitting.
Can you fix an existing broken integration, not build a new one?
Yes, debugging existing integrations is one of my specialties. Send me the error messages, relevant code, and API docs, and I'll diagnose the issue before starting.
What if the project needs more work than the package covers?
I'll let you know as soon as I see the scope is larger, and provide a clear custom quote before doing any extra work. No surprise charges.
Can you also set up ongoing maintenance or monitoring?
Yes, I offer ongoing API maintenance and monitoring as a custom add-on outside of these fixed packages. Message me to discuss your needs and a fair monthly rate.
