Over deze dienst
Need help with eBay API, Shopify API, Amazon SP-API, REST API, SOAP API, or Squarespace API?
I build and fix API integrations so your store/website/app can sync data correctly and run without errors.
I can troubleshoot and resolve issues like 401/403, OAuth/authentication failures, token/refresh token problems, permission/scopes, broken endpoints, bad requests, throttling, timeouts, and incomplete JSON/XML responses. Whether you need a new integration or your existing connection is broken, Ill find the root cause and fix it properly.
Common tasks I handle
- Orders, products, inventory sync (pull/push)
- Data extraction and clean display on screen/dashboard
- Create/update via API (where supported)
- Webhooks setup + scheduled sync (cron) when needed
- Reliable error handling, logging, and validation
What you'll get
- Working, secure integration or bug fix
- Tested API responses (Postman/cURL) and confirmation of correct data
- Clear explanation of what was changed
Before ordering: message me your API docs, goal, current code (if any), and error logs/credentials so I can confirm scope and recommend the right package.

Veelgestelde vragen
What access do you need to start the integration or fix?
I typically need the API documentation, app/client credentials (or developer keys), and either sandbox or live access. If there’s existing code, I’ll also need the repo/files and any server/admin access required to test.
Can you fix 401/403 errors, token failures, and OAuth issues?
Yes. I handle OAuth flows, token/refresh-token issues, scope/permission problems, signature/header mistakes, and account/app configuration errors that cause 401/403 responses.
Do you work with both REST and SOAP APIs (JSON/XML)?
Yes. I can integrate and parse REST (JSON) and SOAP/XML APIs, including proper request formatting, pagination, and response mapping.
Which Amazon APIs do you support—SP-API only or also Ads API?
I support Amazon SP-API integrations and troubleshooting, and can also work on Amazon Advertising API issues depending on your use case and access level.
Can you integrate eBay/Shopify/Squarespace for orders, products, and inventory sync?
Yes. Common tasks include order import/export, product/catalog sync, inventory updates, and customer data pulls—based on what each platform allows and your required workflow.
Will you test everything before delivery? How do you validate results?
Yes. I validate with Postman/cURL and real API calls (sandbox or live), verify response data, and confirm the exact fields you expect (orders/products/inventory) are correct.
Can you work on an existing broken integration without rewriting everything?
Yes. I can debug your current implementation, fix the root cause, and keep changes minimal when possible. If the code is outdated or unsafe, I’ll recommend the cleanest fix.
How do you handle API rate limits/throttling and timeouts?
I implement best practices like retries/backoff, pagination, batching, and request optimization. This prevents random failures and makes the integration stable under load.
Do you support webhooks and scheduled sync (cron jobs)?
Yes. I can set up webhooks for real-time updates where supported, and cron/scheduled jobs for periodic sync, including logging and failure alerts if needed.
What should I send you before ordering to avoid delays?
Please share your goal (what to sync/do), API docs, credentials/sandbox access, current code (if any), and exact error messages/logs/screenshots. Then I’ll confirm scope, timeline, and the right package.
