Fix and Update Custom WooCommerce Checkout Plugin for Rentman API Integration -- 2

Job ID: 38956564

Budget: €30 – €250 EUR

We have a WooCommerce webshop that integrates with the Rentman platform (https://api.rentman.net/) to export orders. This integration is managed using the Rentman plugin (https://www.rentmanplugin.com) which is already installed and functional.

Additionally, we developed a custom plugin, "luxonos-checkout," to customize our checkout page. However, this plugin has stopped working and is now causing issues during the checkout process. The error message displayed is:
"There was an error processing your order. Please check for any charges in your payment method and review your order history before placing the order again. Error details have been logged."

The order also fails to export to Rentman, rendering the integration non-functional.

Potential Causes:
- Updates in the Rentman API
- Updates in the Rentman Plugin
- WooCommerce/WordPress updates
- Other compatibility issues
- Our previous developer is no longer available, so we need assistance to diagnose and fix these issues.

Requirements:
- Update luxonos-checkout plugin:
- Debug and identify the root cause of the issue.
- Ensure compatibility with the latest versions of the Rentman API, Rentman plugin, WooCommerce, and WordPress.
- Fix the checkout functionality to restore the order placement process.

Integration Validation:
- Verify that the plugin exports orders correctly to Rentman once fixed.

Code Documentation:
- Post a detailed changelog on GitHub.
- Include clear comments and documentation for all code changes to ensure maintainability.

Deliverables:
- Fully functional luxonos-checkout plugin.
- Detailed GitHub changelog and well-documented code.
- Verification that the integration with Rentman API is operational.

Skills Required:
- Strong experience with PHP and WordPress plugin development.
- WooCommerce customization expertise.
- Familiarity with RESTful APIs and debugging API integrations.
- Version control (Git) proficiency for documentation and changelog updates.
