FAQ
Can you integrate any custom or niche API even if it is not listed in your description?
Yes. As long as the platform provides REST, GraphQL, SOAP/XML, or Webhook documentation (or a developer sandbox), I can integrate it into your existing website, mobile app, or database.
Can you integrate AI APIs like OpenAI, Claude, or Gemini into my existing web app?
Absolutely. I build custom AI workflows including streaming chat endpoints, automated document parsing, embeddings/RAG pipelines, voice AI (ElevenLabs/Whisper), and automated CRM actions triggered by AI outputs.
What programming languages and frameworks do you support?
I work seamlessly across PHP (Laravel, CodeIgniter, Core PHP), Python (Django, Flask, FastAPI), JavaScript/TypeScript (Node.js, Express, React, Next.js, Vue), WordPress/WooCommerce, and SQL/NoSQL databases (MySQL, PostgreSQL, MongoDB, Redis).
How do you handle API rate limits, OAuth2 token expiration, and failed webhooks?
I implement automated OAuth2 refresh-token rotation, retry mechanisms with exponential backoff, queuing for rate-limited APIs, and webhook signature verification so you never lose data.
Can you connect two platforms that don't natively talk to each other?
Yes. I build custom lightweight middleware scripts (in Python, Node.js, or PHP) or automated webhook pipelines (using n8n, Make.com, or custom cron jobs) to sync data between any two systems in real time.
What do you need from me to get started?
Simply share a brief overview of your current tech stack, the link to the API documentation (or the names of the platforms you want to connect), and staging/sandbox access if available.
Which specific 3rd-party APIs have you already integrated?
I have successfully integrated 54+ APIs across 200+ projects, including Zoho (CRM, One, Books, Inventory), HubSpot, GoHighLevel, ServiceM8, Workiz, Deputy, Shopify, BigCommerce, WordPress, ShipStation, Multivende, Xero, QuickBooks, SevDesk, wFirma, Stripe, PayPal, Aurora Solar, OpenSolar, LeadDocket
Do you build integrations using custom code or tools like n8n, Make.com, and Zapier?
I do both! Depending on your budget and infrastructure, I can write 100% custom backend code (Node.js/MERN, PHP, Python, WordPress, Shopify) to avoid monthly SaaS fees, OR build scalable visual workflows in n8n, Make.com, or Zapier using custom HTTP/Webhook modules.
Can you fix a broken API integration or webhook on my existing website?
Yes! If an API version deprecated, a webhook stopped firing, or OAuth tokens are failing on your WordPress, Shopify, or custom web app, I can debug, patch, and restore the integration quickly.
