Custom WordPress plugins
Custom post types, admin interfaces, REST endpoints, business rules, integrations and site-specific functionality built for maintainability.
BitwiseCode / Build / Plugins & Integrations
Custom WordPress plugins. Reliable API integrations.
When off-the-shelf plugins cannot support the way your business works, we engineer the missing connection. Build custom WordPress functionality, integrate WooCommerce with external systems, and automate workflows with reliable APIs, webhooks and background processing.

Our capabilities
Engineering for the functionality your business actually needs.
From a single plugin feature to a multi-system workflow, the scope follows your requirements and the APIs each platform provides.
WooCommerce extensions
Checkout logic, payment events, inventory synchronization, product rules, order workflows and custom purchasing experiences.
Third-party API integrations
Integrate payment providers, CRMs, ERPs, shipping services, membership platforms and specialist APIs using supported interfaces.
Webhooks & workflow automation
Event-driven processes, scheduled synchronization, notifications, retries, deduplication and controlled background jobs.
Import, export & syncing
Connect product feeds, inventory records, customer data and external systems with validation, error reports and clear data mapping.
Repair & modernization
Debug unreliable integrations, refactor brittle plugins, resolve API failures and move legacy implementations toward supported APIs.
Built for production
A working integration needs more than a successful API call.
Systems time out. Webhooks arrive twice. Data changes unexpectedly. Our approach considers these realities while making the solution easier to operate and maintain.
- Authentication & data validationProtect credentials, validate input, check permissions and use least-privilege access where supported.
- Idempotency & duplicate protectionHandle repeated events without repeating payments, orders or other side effects.
- Retries, logs & diagnosticsMake errors visible and design sensible recovery paths for interrupted requests.
- Compatibility & maintainabilityUse WordPress and WooCommerce APIs where appropriate, with tested upgrade and deployment paths.
Typical integration challenges
Connect software without creating more manual work.
Some examples of the types of workflows we can scope and implement.
External payment callbacks
Map payment status back to WooCommerce or a learning platform, handle pending and failed events, and prevent duplicate fulfillment.
Product & stock synchronization
Move quantities, pricing and product updates between stores, warehouses and upstream suppliers with clear conflict handling.
CRM & lead workflows
Route form submissions into sales tools, validate records, notify the right person and reduce copy-and-paste administration.
Search & content services
Integrate search indexes, content APIs and scheduled data feeds that need more control than a ready-made connector provides.
Delivery process
A controlled route from requirements to deployment.
Map the workflow
Understand current systems, events, data fields, failure cases and who relies on the outcome.
Review the APIs
Confirm authentication, access, rate limits, webhooks and data mapping before implementation.
Build & test
Implement the integration and test happy paths, duplicates, failures and recovery scenarios.
Deploy & hand over
Verify the live flow, provide practical documentation and define maintenance needs.
Frequently asked
Questions about plugins & integrations.
Can you build a plugin for an existing WordPress website?
Yes. We can build site-specific features or standalone plugins around your current environment, including hooks, settings screens, custom data and REST endpoints.
Can you integrate an API that has no WordPress plugin?
Often, yes. We first review the API documentation, authentication method, permissions, rate limits and required behavior to establish feasibility.
Do you work with WooCommerce payments and inventory?
Yes. Payment callbacks, order state transitions, product imports and stock synchronization can be designed using WooCommerce's supported APIs and hooks.
Can you repair a failing plugin or integration?
Yes. A typical starting point is diagnostics: reproduce the failure, inspect logs and request data, then identify a maintainable fix.
What if the third-party API fails or goes offline?
Where the use case warrants it, we design timeouts, retries, logging, duplicate protection and recovery options. Exact guarantees depend on the external provider.
What do you need for a project estimate?
Share your website, the external service or API documentation, what should trigger the workflow, expected results and any existing error examples.
