I will fix mobile app payment gateway and checkout, stripe api, API
Shedrach E
About this gig
Is your mobile app payment failing, checkout stopping, transactions not confirming, webhooks not firing, or users getting payment errors?
The cause may be a payment gateway configuration, API authentication issue, invalid request, webhook failure, callback problem, SDK conflict, backend error, or incorrect checkout logic.
I will troubleshoot and fix mobile app payment and checkout issues involving Stripe, PayPal, Paystack, payment APIs, webhooks, callbacks, transaction status, and backend connections.
I can investigate failed payments, missing transaction updates, broken checkout flows, authentication errors, and gateway issues.
I review the payment flow, trace the request through the app, API, gateway, webhook, and backend, then fix the failing point and test the flow.
Why work with me?
I treat payment problems as technical troubleshooting, not guesswork. You get clear communication, focused debugging, careful testing, and a scope based on your actual issue.
Send your app platform, gateway, error message, logs, and affected flow.
Ensure you contact me first before placing an order
