FAQ
What types of APIs do you integrate?
REST, SOAP, GraphQL, and webhook-based APIs. This includes payment gateways (Stripe, PayPal), CRMs (Salesforce, HubSpot), e-commerce (Shopify, WooCommerce), messaging (Twilio), maps, AI (OpenAI), and custom endpoints.
Which tech stacks do you use for API development?
Backend: Node.js, Python (Django, Flask), PHP (Laravel), .NET, Express.js. Frontend: React, Vue.js, plain JavaScript. If your project needs a specific stack, message me and I'll confirm.
Do you provide custom API development?
Yes — I build APIs from scratch (REST or SOAP), design the endpoints and authentication, document them, and deliver a working staging environment. Custom API builds fall under the Premium package.
Can you integrate APIs for mobile apps?
Yes — I integrate APIs with iOS, Android, React Native, and Flutter apps. This includes handling authentication, response caching, and offline-friendly patterns where relevant.
How long does API integration take?
Simple single-endpoint integrations: 3 days. Multi-endpoint work: about a week. Full custom API builds with automation: 2–4 weeks. I confirm the exact timeline in the scoped plan before you order.
Do you handle authentication (OAuth, API keys, JWT)?
Yes — OAuth 2.0, API keys, JWT, HMAC signatures, basic auth, and custom token flows. I also handle token refresh, secure credential storage, and rate-limit-safe retry logic.
Can you automate data synchronization with APIs?
Yes — I build scheduled sync pipelines, real-time webhook listeners, and workflow automations using Zapier, Make, n8n, or custom cron/queue systems depending on volume and reliability needs.
Do you offer support after integration?
Yes — Premium includes 1 month of support for anything related to the delivered work. If an API changes later or you need new endpoints added, message me and I'll send a custom offer.
Do you integrate APIs I don't see listed here?
Yes — I list common ones like Stripe, Salesforce, HubSpot, Shopify, and Twilio because those come up most often, but I integrate any REST, SOAP, or third-party API with proper documentation. Send me the API docs and I'll confirm compatibility before you order.
What do you need from me to start?
API documentation (links or PDFs), sandbox/test credentials, a short description of what you need the integration to do, and access to the codebase where the integration goes. The clearer the docs, the faster the delivery.
