FAQ
What backend technologies do you work with for API integrations?
I work with Node.js/Express and .NET Core/C#. I can also work with existing backends in other languages if they're well-documented.
Can you integrate an API not listed above?
Most likely yes. Share the API name or documentation link and I'll confirm within a few hours whether I can integrate it and give you a price estimate.
Do you set up webhooks as part of the integration?
Yes. Webhook setup and event-driven handling is included in the Standard and Premium packages, and available as an add-on in Basic.
Can you integrate into a React or Angular frontend directly?
Some lightweight APIs can be called from the frontend, but most require a backend for security reasons (hiding API keys, handling OAuth). I'll recommend the best and most secure approach for your specific case.
I need Twilio SMS + WhatsApp together — is that one or two integrations?
That counts as two integrations since they are separate APIs with separate setups. The Standard package would cover both.
Can you integrate Shopify APIs into a non-Shopify app?
Yes. I can integrate Shopify's REST or GraphQL APIs into any backend to sync products, orders, customers, or inventory with an external system.
What if the third-party API changes after you deliver?
API changes outside my control aren't covered under the free support period, but I'm happy to help with updates at an agreed hourly rate.
Can you sign an NDA before starting?
Yes, absolutely. I'm happy to sign an NDA before reviewing any sensitive project details.
