I will integrate apis and payment gateways into react native mobile app development
Annie
About this gig
Your React Native app is built, but the API or payment functionality still needs to work properly?
I'll integrate APIs and payment gateways into your existing React Native app so your users can actually sign in, access data, complete transactions, and use the features connected to your backend.
I can help with:
- REST API & third-party API integration
- Authentication and protected API requests
- Stripe and PayPal payment integration
- Payment status and transaction handling
- Webhooks and callback handling
- Firebase/API integrations
- Testing and connecting the complete flow
Whether you need a new API connected, a payment gateway added, or an existing integration fixed, Ill work with your current React Native codebase and integrate the required functionality cleanly.
What I need from you:
Existing React Native source code
API documentation and credentials
Payment gateway account/details, if applicable
Clear requirements for the integration
I do not build complete backend systems under this gig. If you need backend/API development as well, message me before ordering so we can define the scope properly.
Send your app details and integration requirements & I'll recommend the right package
