I will integrate third party API, webhooks and authentication
Joey
About this gig
Does your web application need to connect with a third-party API?
I can help you integrate external APIs into your existing application and handle the technical connection properly.
I work with REST APIs, API authentication, OAuth, JWT, webhooks, JSON data exchange, payment APIs, business platforms, and backend integrations.
What I can help with:
- Third-party API integration
- REST API connection
- OAuth and JWT authentication
- API key authentication
- Webhook setup
- Data mapping and synchronization
- API error troubleshooting
- Stripe and payment integrations
- Shopify and WooCommerce APIs
- WordPress API integrations
- Node.js and Python backend integrations
The goal is simple: connect your systems reliably so data can move between your application and the external service as expected.
Before ordering, send me the API documentation, your current application details, and what you need the integration to accomplish.
Message me first so I can review the requirements and recommend the appropriate package.

FAQ
Can you integrate an API into my existing application?

Can you set up webhooks?
Yes. I can configure webhook endpoints, process incoming events and connect them to the required application workflow.
Can you fix an existing API integration?
Yes. If an existing integration is returning errors or failing to exchange data correctly, I can investigate the implementation and identify the issue.
Do you work with Stripe, Shopify or WooCommerce?
Yes, when the requested integration is supported by the platform's available APIs and your requirements comply with the platform's terms.
What do you need before starting?
Usually the API documentation, API credentials where appropriate, access to the relevant code/application, and a clear description of the expected result.
