Enhance Middleware Platform & WooCommerce Plugin
Budget: $60 – $90 USD
This project centers on improving/creating an already attempted middleware platform and WooCommerce plugin to integrate with Stripe Connect, enabling multiple WooCommerce stores to connect, apply platform fees, log transactions, and handle Stripe webhooks. Payments are not processed here; only platform fees are collected, and transaction details are logged.
Middleware
1. Stripe Account Storage: Middleware stores Stripe Account IDs per WooCommerce store following OAuth authorization.
2. Platform Fee Management: Admins can configure fees (percentage and/or fixed), which the WooCommerce plugin retrieves for each transaction.
3. Transaction Logging: Logs order ID, amount, and platform fee after WooCommerce order completion.
4. Webhook Handling: Processes Stripe webhooks (e.g., charge.succeeded) to log transaction updates.
WooCommerce Plugin
1. Display Platform Fee on Checkout: Retrieves fee configuration from middleware to display at checkout.
2. Apply Platform Fee: Adds calculated platform fee to the total order amount.
3. Sync Transaction Data: Sends transaction details (order ID, amount, fee, Stripe charge ID) to middleware after successful orders.
4. Stripe Connection: OAuth flow for WooCommerce store owners to connect their Stripe accounts via middleware.
Stripe
1. OAuth Authorization: OAuth flow enables WooCommerce stores to connect, returning an authorization code for middleware to exchange for a Stripe Account ID.
2. Payment Processing and Fee Collection: Stripe processes payments, collecting the configured platform fee.
3. Webhook Notifications: Notifies middleware of charges, refunds, and key events for real-time transaction logging.
Infrastructure
- Hosting: Middleware is hosted on Vultr with PHP and MySQL
- Database: MySQL stores users, Stripe accounts, fees, and transaction logs, with credentials managed in a secure `.env` file.
--------------------------------------------------------------------------------------------------------------------
Middleware Functions
- OAuth with Stripe Connect: Handles authorization flow for store owners, linking WooCommerce URLs to Stripe Account IDs.
- Platform Fee Management: Allows fee configuration through an admin dashboard, fetched by the plugin for transactions.
- Transaction Logging: Logs order and platform fee details, viewable by admins.
- Webhook Processing: Handles Stripe events, verified via Signing Secret for integrity.
WooCommerce Plugin Functions
- Stripe OAuth Connection: Initiates “Connect to Stripe” option in WooCommerce, passing authorization code to middleware for account ID.
- Platform Fee Calculation: Fetches fee configuration from middleware, displaying it at checkout.
- Transaction Syncing: Sends order and fee details to middleware post-order completion.
- Secure Communication: Uses HTTPS for middleware communication.
Database Structure
- stripe_accounts: Stores Stripe Account ID associated with each WooCommerce store.
- platform_transactions: Logs WooCommerce transactions with order ID, amount, fee, and charge ID.
- platform_fee_config: Stores platform fee settings.
- users: Manages admin and user roles.
Stripe Configuration
- Client ID: Used for OAuth, accessible in Stripe Connect settings.
- Secret Key: Used for API requests, stored securely in `.env`.
- Redirect URI: For OAuth redirection.
- Webhook URL: Middleware webhook handler.
- Signing Secret: Verifies webhook authenticity, stored in `.env`.
Most of the work has been performed already and this is a fixed project. I can provide both the zip for the middleware and WP plugin if you're interested in the project to review and advise me your thoughts so far on it.
