I can help you resolve the authentication, service management, and billing calculation issues in your ConvoyPanel API–integrated system. I have strong experience working with API integrations, debugging complex billing logic, and implementing secure user authentication protocols. Once I review your project files, I’ll identify the root causes of login failures, fix the purchase/modify service functionality, and ensure accurate billing calculations to eliminate incorrect charges. Could you clarify: * Which authentication method the system currently uses (e.g., OAuth, token-based)? * Are billing inaccuracies related to tax/discount calculations or usage tracking? I’m available to start immediately and can provide a detailed timeline and cost estimate after reviewing the code.

@Alanfox10000

I can review and fix your ConvoyPanel API–integrated billing system so authentication works reliably, services can be purchased/modified without errors, and billing is accurate. I’ve debugged and optimized API-driven billing platforms where auth flows, service logic, and calculations all needed alignment with third-party APIs. Method: Code & API Review: Examine project files, API docs, and current integration points. Authentication Fix: Trace login flow, token exchange, and identity verification; resolve session handling and error states. Service Management Debug: Validate API requests for service purchases/modifications; ensure payloads match ConvoyPanel requirements. Billing Accuracy: Audit pricing logic, tax/fee calculations, and rounding; add test cases for edge scenarios. Error Handling & Logging: Improve visibility into API errors for faster troubleshooting. Testing: Run unit/integration tests with sandbox data before production push. I’ve delivered fixes for payment and provisioning systems where small API mismatches caused big user-facing issues—so I’ll ensure stability before handoff. Quick questions: • Which language/framework is the current system built in? • Do you have ConvoyPanel API sandbox/test credentials? • Is authentication via API key, OAuth, or custom JWT? • Are billing rates fixed or pulled dynamically from ConvoyPanel? • Any urgent deadlines for fixes?
