Need a WordPress / WooCommerce plugin developer

Budget: 27000 UAH Deadline: 10 days

So, WooCommerce plugins were developed - not just theme modifications, but specifically order logic, API integrations, admin settings, error logs, and Git.

The cost estimate is from 28,000 UAH, timeline - about 10 working days after reviewing the specifications and API documentation. If the specifications include complex message template logic, retries for sending, queues, or multilingual support - the estimate may change.

The approach I see is this - we create a separate plugin without tying it to the theme, connect to WooCommerce order statuses, expose keys and parameters in the admin panel, add logging for API responses and errors, as well as a proper structure for future support. We can keep it simple, but it’s important not to make a fragile insertion in functions.php =)

Questions
> Is there already documentation for the external API with examples of requests and responses?
> Should messages be sent only when the order status changes or also upon creation, payment, cancellation, return?

Similar experience
> https://business.ingello.com/eva - e-commerce and integration logic for retail
> https://business.ingello.com/prime-eva - complex processes around products, orders, and internal systems
> https://business.ingello.com/vorfahr - example of an integration system with process automation

Main page of Ingello for the exchange
> https://systems-fl.ingello.com/ua

Please send the specifications and API description - after that, I will provide a more accurate estimate by stages. I would say, here the main thing is not to write code, but not to turn the store into a small museum of technical debt. Expand

Hello. I have experience in developing WordPress + WooCommerce plugins, as well as experience in integrating third-party APIs. I would like to review the technical specifications.

Budget: 5000 UAH Deadline: 30 days

I will develop a custom plugin for WooCommerce strictly according to your specifications in the form of an isolated OOP module with its own settings page, logging via WC_Logger, and version control in Git.

Since direct synchronous requests to external REST APIs during order status changes can critically slow down the site or even block the checkout process for the customer in case of a failure on the notification service side, is the use of an asynchronous task queue through the built-in Action Scheduler or WordPress Cron included in your specifications?

We can discuss the budget and timelines in personal correspondence.

Маю прямий досвід розробки кастомних WordPress/WooCommerce плагінів та mu-plugins — не просто сайтів, а саме серверної логіки WooCommerce.

Чи розробляв WooCommerce-плагіни? Так:

- loyalty-pricing.php — кастомний mu-plugin: роль client_fidele, поле _loyalty_price в редакторі товару, фільтр woocommerce_product_get_price для двохрівневих цін, badge
"Prix Fidélité", колонка в admin
- nstudio9-smtp.php — кастомна SMTP конфігурація через хук phpmailer_init, без залежності від плагінів
- auto-backup.php — mu-plugin: WP Cron кожні 4 години, дамп БД + файлів, ротація бекапів
- Інтеграція Points & Rewards — кастомні хуки: woocommerce_email_order_details (email про бали після замовлення), woocommerce_before_cart (баннер балів), налаштування через
update_option
- Free shipping progress bar — хуки woocommerce_before_cart, woocommerce_before_checkout_form, woocommerce_widget_shopping_cart_before_buttons
- Custom order numbers — послідовна нумерація NS-4524+ з OpenCart міграції
- Email routing — woocommerce_email_recipient_new/cancelled/failed_order + wpcf7_mail_components для дублювання на кілька адрес

WooCommerce hooks з якими працюю щоденно:
- Order status hooks, price filters, cart/checkout hooks
- gettext фільтри для перекладу WooCommerce на французьку
- Product loop customization (кнопки, badges, meta)
- Shipping zones/methods програмно

Інтеграції з зовнішніми API:
- Stripe API (live payments, webhook handling)
- PayPal Payments (PPCP OAuth flow)

Hello.

Yes, I have worked with WooCommerce plugins - including custom integrations via API, order status hooks, logging, and separate settings pages in the admin panel. It is important to make the plugin a proper separate architecture, not just a "patch" over the theme or functions.php.

I can review the technical specifications, provide an adequate assessment of the implementation right away, and suggest the optimal integration option with the API so that the plugin is well-supported and does not break after WooCommerce updates.

Budget: 7000 UAH Deadline: 7 days

Hello! The task of developing a custom WooCommerce integration plugin with an external API service for sending notifications is completely clear. What is needed here is clean code, working with hooks, and proper architecture, not ready-made builders.

Let's get straight to the point: I have the necessary technical background to create a reliable extension. I make all changes and custom solutions carefully, making surgically precise adjustments to the logic without creating technical debt, so the plugin works stably, does not conflict with the theme or other modules, and is easy to update.

Clear answers to your questions:

Experience in developing WooCommerce plugins: Yes, I develop custom plugins and PHP scripts for WordPress/WooCommerce. I am well acquainted with the internal architecture of the CMS, the WordPress Coding Standards (WPCS), and the WooCommerce order lifecycle. Here is an example: https://freelancehunt.com/showcase/work/rozrobka-plaginu-dlya-povnoyi-kastomizatsiyi-checkout/2010308.html

Examples of similar work: I have created modules for e-commerce automation, specific subscription systems, payment integrations, and database synchronization tools. I will provide links to relevant code and architectural details immediately during the discussion.

Experience with integrations with external APIs: Yes, this is one of my main specializations. I have implemented order synchronization with CRM systems (specifically, KeyCRM) via API, worked with webhooks, and transferred customer and product data.

Technically, the plugin will be implemented according to the following algorithm:

Notification logic: Connecting to hooks for order status changes (for example, woocommerce_order_status_changed or specific ones like woocommerce_order_status_processing).

Working with the API: Using secure standard WordPress functions (wp_remote_post / wp_remote_get) to interact with your REST API.

Admin panel: Creating an isolated settings page through the Settings API to manage API keys, message templates, and status selections.

Security and logging: Validating and sanitizing data, using WC_Logger to log errors and API responses in a separate log file that can be viewed directly from the WooCommerce admin. All code is maintained in Git.

I will be able to assess the exact cost and timeline immediately after reviewing your technical specifications. Please send the technical task, and I will study it right now and provide a final estimate. I am ready to start working. Expand

Hello. I have experience in developing plugins for WordPress. I am ready to collaborate. Feel free to contact me.

Budget: 10000 UAH Deadline: 2 days

Hello!

I am ready to review the technical specifications and implement a custom plugin for WordPress + WooCommerce for integration with an external API service for sending client messages.

I have experience specifically in the technical development of WordPress / WooCommerce, including working with hooks, custom logic, settings pages in the admin panel, WooCommerce order status hooks, REST API integrations, error handling, and modifying existing projects without disrupting the main logic of the site.

In my Git, there is a support system that I use on my sites, messages are sent from different sites to one backend, and duplicated in Telegram from where I can respond to user messages https://github.com/ASGRU/universal-support-chat

For your project, I can implement:

* a separate custom WordPress plugin
* integration with WooCommerce
* reaction to the necessary order statuses through WooCommerce hooks
* sending data to an external API
* a settings page in the WordPress admin panel
* fields for API keys / tokens / integration parameters
* configuration of events when messages should be sent
* logging of successful and erroneous requests
* API error handling
* secure storage of settings
* testing on different order scenarios
* preparation of the plugin for further expansion
* working through Git, if required in the project

Answers to your questions:

1. Have you previously developed WooCommerce plugins?
Yes, I have worked with custom WooCommerce logic, order hooks, order statuses, checkout/order flow modifications, integrations, and custom functions for specific business processes.

2. Can you show examples of similar work?
Yes, I can show or describe relevant examples in private correspondence: WooCommerce modifications, custom integrations, order automation, data transfer to external services, working with digital products and custom order processing scenarios.

3. Do you have experience with integrations with external APIs?
Yes, I have experience with external REST API integrations: sending data, authorization via keys/tokens, handling API responses, logging errors, rechecking requests, and configuring integration parameters through the WordPress admin panel.

The exact estimate depends on the scope of the technical specifications, the number of API scenarios, message logic, authorization, and the need for a queue. Expand

Hello. I have experience in developing custom WordPress/WooCommerce plugins, working with WooCommerce hooks, order statuses, admin settings, REST API, and error logging.

I can review your specifications, estimate the timeline and cost, after which I will implement the plugin according to your logic. As a result, you will receive a separate WooCommerce plugin that will integrate with an external API, send client notifications for the necessary events/order statuses, have a settings page in the admin panel, and handle errors correctly.

I work carefully, without modifications to the core of WordPress/WooCommerce, with a proper code structure, so that the plugin can be maintained and developed further.
