Paystack API + MySQL Database Integration

Here's an improved and detailed version of your project description tailored for developers: --- ### **Paystack API Integration with MySQL Database** This project involves building a seamless integration of Paystack's API with a MySQL database to manage customers, process payments, and handle funds transfers efficiently. Below are the specific requirements for implementation: --- ### **1. Customer Management** - **Create Customer**: - When a new customer is added to the `customers` table in the MySQL database, automatically create the corresponding customer in Paystack using the `/customer` API endpoint. - Set the customer's risk action to `'allow'` via the `/customer/set_risk_action` endpoint. - Ensure the customer's unique Paystack ID is stored in the database for future reference. - **Deactivate Customer**: - When a customer is deactivated in the system, update their risk action to `'disallow'` using the `/customer/set_risk_action` endpoint. --- ### **2. Payment Page** - **Endpoint**: - Create a payment page at `/paymentrequest` where logged-in users can initiate payments. - **Implementation Details**: - Use Paystack's `/transaction/initialize` and `/transaction/verify` endpoints to process payments. - On successful payment verification: - Record the transaction in a `transactions` table, capturing all necessary details (e.g., customer ID, amount, status, Paystack reference). - Credit the customer's account in the `customerdeposits` table by updating their balance. - **Error Handling**: - Implement robust error handling for failed payments, incomplete verifications, or API call issues. - Log errors for debugging and system monitoring. --- ### **3. Funds Transfer** - **Funds Transfer Page**: - Create a page where a client from one company can transfer funds to another client in a different company. - **Workflow**: - Debit the sender's account in the `customerdeposits` table. - Credit the recipient's account in the `customerdeposits` table. - Record the transaction in a `transaction_history` table with fields for sender, recipient, amount, date, and transaction status. - **Transaction Validation**: - Ensure sufficient balance in the sender's account before initiating the transfer. - Send notifications (email or SMS) to both parties upon a successful transfer. --- ### **Additional Development Notes** 1. **Database Design**: - Ensure the `customers`, `customerdeposits`, and `transactions` tables are well-structured, with proper indexes for performance optimization. - Add a `paystack_customer_id` column to the `customers` table to store the unique identifier from Paystack. 2. **Authentication**: - Secure the payment and transfer pages with proper user authentication and role-based access control. 3. **Logging**: - Log all API interactions (requests and responses) to an `api_logs` table for debugging and auditing purposes. 4. **Testing**: - Conduct end-to-end testing of all workflows in a sandbox environment before deploying to production. - Test edge cases, including network issues, API timeouts, and invalid data inputs. 5. **Documentation**: - Provide clear documentation for each implemented feature, including API endpoints, database schema changes, and workflow diagrams. --- ### **Deliverables** - Fully functional Paystack API integration with the MySQL database. - Payment page at `/paymentrequest`. - Funds transfer page for inter-company transactions. - Updated database schema with customer and transaction tables. - Comprehensive error handling and logging system. - Detailed documentation for setup, deployment, and maintenance.
