I will integrate rest apis and webhooks into your application
Dante Z.
About this gig
Need an existing app connected to a REST API? I will implement a focused integration in your Node.js/TypeScript, C#/.NET, or Flutter codebase.
I am a full-stack software engineer with 8+ years of experience building backend services, REST APIs, business automations, data import/export tools, and integrations for enterprise and SaaS products.
Depending on the package, I can:
- connect documented REST endpoints
- add API key, Bearer token, or JWT authentication
- map and validate JSON data
- handle errors and common edge cases
- implement one incoming or outgoing webhook
- add a focused integration check and handoff notes
Every package covers one existing application and one API provider. Please contact me before ordering if the API uses OAuth, has incomplete documentation, requires provider approval, or handles payments or sensitive production data.
Not included: a new application or UI, API subscription fees, provider approval, deployment, or ongoing maintenance.

FAQ
What technologies do you work with?
I work with existing Node.js/TypeScript, C#/.NET, and Flutter applications. Please contact me first if your project uses another stack.
What counts as one endpoint?
One endpoint is one API operation, such as GET /customers or POST /orders. Different routes or HTTP methods count separately.
Do you support OAuth or undocumented APIs?
These vary significantly by provider. Send the documentation before ordering; OAuth, incomplete documentation, or provider review may require a custom offer.
How should I provide credentials?
Sandbox or test credentials with minimum permissions are preferred. Please do not send secrets before the scope is agreed, and rotate temporary keys after delivery.
Does the package include deployment or a new application?
No. It covers integration into one existing codebase and source-code handoff. Deployment, a new UI or application, ongoing maintenance, and work beyond the agreed scope require a custom offer.
