About this gig
Need a secure API, authentication, or payment integration for your React or Next.js application?
I will connect your application to documented third-party services using maintainable TypeScript code, secure server endpoints, and proper loading, success, and error handling.
I can help with:
- REST API integration using Axios or Fetch
- Stripe, PayPal, Adyen, or another documented payment provider
- Checkout, subscriptions, payment status, and webhooks
- Firebase, Supabase, JWT, OAuth, and social authentication
- Login, signup, password reset, and protected routes
- Secure Next.js API routes or serverless functions
- Token handling, data mapping, and form integration
- Repairing incomplete or failed integrations
Sensitive credentials will not be exposed in browser code. Testing will begin with sandbox credentials whenever available.
Please contact me before ordering payment, subscription, webhook, or undocumented API work so I can confirm the scope and correct package.

FAQ
What do you need to begin?
I need your project source code or repository, API documentation, a description of the required user flow, and sandbox or test credentials when applicable.
Can you integrate any third-party API?
I can integrate documented REST APIs that provide the necessary endpoints and credentials. Please send the documentation before ordering so I can confirm the scope.
Can you implement login and signup?
Yes. I can implement login, signup, logout, protected routes, token handling, password reset, social login, and role-based access depending on the selected package.
Can you integrate payment subscriptions?
Yes. Subscription billing usually requires backend endpoints, webhooks, and additional testing, so please contact me for a custom offer.
Do you provide backend development?
The Standard and Premium packages can include small Node.js, Express, or serverless functions needed for the integration. A complete custom backend is not included unless agreed through a custom offer.
Will you use production payment credentials?
Integration and testing should begin with sandbox or test credentials. Production keys should only be configured securely after the integration has been tested.
Can you fix an incomplete integration?
Yes. Please provide the current source code, the expected behavior, error details, and relevant API documentation before ordering.
What counts as one API endpoint?
One endpoint is one API operation, such as retrieving users, submitting a form, creating a payment, or updating a profile. Multiple methods or workflows may count as separate endpoints.
