FAQ
Which APIs can you integrate?
Any REST or GraphQL API with documentation. Most common: Razorpay, Stripe, Twilio, SendGrid, OpenAI, Google APIs, Firebase, WhatsApp Business, Telegram, Shopify, and many more. Message me with your specific API and I'll confirm.
Do you set up webhooks too?
Yes. Webhook setup, signature verification, and event handling are included in the Standard and Premium packages. For Basic, webhooks are available as an add-on.
What if the API has no documentation?
Please share whatever docs or Postman collection you have. If the API has zero documentation, message me first so I can assess feasibility before you order.
Will you integrate into my existing codebase?
Yes. Share your code via GitHub or zip and I will integrate directly into your existing project — not a separate demo. You get a clean PR or updated files ready to deploy.
