API Integrations for Websites and Online Stores
Moving data by hand between your website and other systems wastes time and invites mistakes. An API integration links your site or online store directly to stock, ERP, CRM, courier or other services, so information flows automatically.
API Integrations
- REST API
- JSON
- Webhooks
- PHP
- JavaScript
- WooCommerce REST API
01
What you get
Data flow mapping
Which data is exchanged, in which direction, how often and which system is the source of truth.
Product and stock sync
Prices, stock levels and descriptions updated automatically from your warehouse or ERP.
Passing on orders and enquiries
New orders and enquiries sent straight from the site to your CRM, accounting or another system.
Webhooks and automations
Actions triggered by specific events, such as a payment, a status change or a new subscriber.
Logging and error alerts
A record of every exchange and an alert when something fails, so no data goes missing unnoticed.
02
Process
API documentation
Reviewing the external system's documentation and access to confirm what is possible.
Integration spec
Which fields map to which, when the sync runs and how errors are handled.
Build and test
Development on a staging environment and testing with realistic but safe data.
Launch and monitoring
Switching the integration on and watching the logs closely during the first few days.

A good fit for
- Online stores whose stock or ERP lives outside the site
- Companies that enter enquiries into a CRM by hand
- Businesses whose data needs to appear on the site in real time
- Sites that need to feed data into marketing tools
- Projects using an external service with no ready-made plugin
Less manual work
No more copying data from one system to another.
Fewer errors
Prices and stock on the site match what is in the warehouse.
Visibility when things go wrong
Logs show what happened, and alerts flag problems early.
What an API integration actually is
An API is how two systems talk to each other. If your stock management software has an API, your website can ask it how many units of a product are available instead of someone typing the number in. If your CRM has an API, a new enquiry from your site can appear in it automatically.
Ready-made plugin or custom integration
Popular services often have a ready-made plugin, and that is checked first. A custom integration is built when there is no plugin, when it does not cover your case or when the system is internal. The code is then written as a dedicated WordPress plugin or a standalone service, depending on the job.
The most common integrations
- syncing products, prices and stock between an online store and a warehouse or ERP
- sending orders to accounting or stock systems
- passing form enquiries to a CRM or email marketing tool
- courier and payment services for online stores, covered in detail under e-commerce solutions
- event tracking in Google Analytics 4
Reliability
An integration is not finished just because it worked once. It has to cope with dropped connections, changed data and an external system that is temporarily down. That is why it includes retries, logging and error alerts, and with large volumes the sync is split into batches so it does not overload the site.

FAQ
Frequently asked questions
Can my site connect to our stock management software?
If the software has an API or can export data, usually yes. The first step is reviewing its documentation and access options.
What do I need to get started?
The name of the system, access to its API documentation and a description of which data should flow and in which direction.
What happens if the external system goes down?
The integration is built with retries and error alerts, so no data is lost without anyone noticing.
Will the integration slow my site down?
It should not. Heavy operations run in the background or in batches, not every time a page loads.
