I will integrate apis and webhooks into your web app
Hadiqa S.
About this gig
Need an API, webhook, or external service connected to your web app?
Im a full-stack developer working with TypeScript, React, Node.js, and modern web stacks. I build reliable integrations that connect your product to the tools your business already uses.
I can help with payments and subscriptions, authentication, identity/KYC, maps and location, email and messaging, CRM and analytics, market/data services, webhooks, and other documented APIs. Examples include Stripe, Square, Clerk, Veriff, Google Maps, Twilio, Mailgun, Mailchimp, HubSpot, and similar platforms.
I handle more than the API call. Depending on your package, I can implement authentication, request/response mapping, webhook events, database updates, validation, error handling, testing, and frontend/backend wiring.
You'll receive clean source code and a tested integration built around the exact workflow you need.
This Gig is for general API and service integrations. For AI-specific features such as chatbots, RAG, or LLM workflows, please use my dedicated AI integration Gig.
Please message me before ordering Standard or Premium with the service/API, documentation, your current stack, and the result you want.

I'm a full-stack software engineer with 4 years of experience building and improving SaaS products, marketplaces, booking systems, fintech platforms and real-time applications. I work across React, Next.js, Node.js, APIs, databases, authentication, payments, AI-powered features and third-party integrations. I've built products from scratch and worked inside large existing codebases to debug, extend and ship complex functionality. If you have an idea, unfinished SaaS, broken app or integration problem, send it my way.

FAQ
What types of services can you integrate?
I can connect most well-documented APIs and webhooks, including payments, authentication, KYC/identity verification, maps, messaging, email, CRM, analytics, business tools, market/data services and other external platforms.
Can you integrate any API?
I can work with most well-documented APIs. Private, undocumented, restricted or unusually complex APIs need to be reviewed before ordering. Send me the documentation and the result you need, and I’ll confirm the scope.
Can you work with my existing web app?
Yes. This Gig is designed primarily for adding integrations to existing applications. I work with TypeScript/JavaScript stacks including React, Next.js and Node.js, and I can review your current setup before the order.
Can you add OAuth, API keys or other authentication?
Yes. I can work with common API authentication methods including API keys, bearer tokens, JWT and supported OAuth flows. Complex OAuth or multi-account authorization may require Standard, Premium or a custom offer.
Can you create and handle webhooks?
Yes. I can send or receive webhooks, validate incoming events, process payloads, update your database and connect events to your application workflow.
Can you integrate payments, authentication or KYC services?
Yes. Depending on the project, I can work with services such as Stripe, Square, Clerk, Veriff and similar platforms. Please message me first for payment, identity or verification flows so I can confirm the required scope.
Do you also do AI API integrations?
This Gig can cover a simple API connection to an AI service, but AI products such as chatbots, RAG systems, LLM workflows or AI-powered features belong in my dedicated AI integration Gig.
What counts as a revision?
A revision covers reasonable adjustments to the agreed integration. Adding a new service, workflow, feature, endpoint group or major business rule is additional scope and may require an extra or custom offer.
