FNO Services Europe
API Integration Services for Small Businesses
Custom API development and integration
Connect your website, ecommerce store and business systems so information can move between them automatically, accurately and securely.
FNO Services Europe provides API integration services for small businesses that need to connect websites, marketplaces, product feeds, payment providers, customer-management systems, reporting tools and other third-party platforms.
We can work with an existing WordPress, WooCommerce, Drupal, Shopify or custom PHP website, as well as older applications that need to communicate with newer services.
The goal is practical: reduce repetitive manual work, prevent data-entry mistakes and give your team a more reliable flow of information between the systems it already uses.
What are API integration services?
An API, or application programming interface, allows one software system to exchange information with another. An API integration connects those systems and controls how information is requested, validated, transformed and stored.
For example, an ecommerce store may need to:
- Receive product information from a supplier
- Send new orders to a fulfilment system
- Update stock levels across several marketplaces
- Retrieve prices or delivery information
- Send customer details to a CRM
- Import payment or transaction records
- Generate reports using data from several services
A reliable API integration service handles more than the initial connection. It must also account for authentication, data formats, failed requests, rate limits, duplicate records, logging and changes introduced by third-party platforms.

Custom API integration services for existing websites
You do not necessarily need a new website to benefit from automation. Many API projects involve improving an existing system rather than replacing it.
We can review how your current website stores and processes information, identify where data should enter or leave the system and build an integration around the existing workflow.
This may include:
- Adding an API connection to a custom PHP application
- Connecting WooCommerce to a supplier or external system
- Importing products into an existing ecommerce database
- Sending website enquiries to a CRM
- Replacing spreadsheet-based processes with scheduled automation
- Creating webhooks for near-real-time updates
- Building a secure internal API for an existing application
- Transferring data between platforms that use different formats
Where an existing system has uncertain ownership, documentation or access, our Website Takeover Check can help establish what is available before integration work begins.
API development and integration services
Some projects require us to connect to an existing third-party API. Others require additional development on your own website or application.
Third-party API integration
We connect your system to an API supplied by a marketplace, payment provider, CRM, supplier or other software company.
Custom integration development
We create the application logic needed to request, validate, transform and store data according to your business rules.
API endpoints for existing systems
Where appropriate, we can add controlled endpoints that allow authorised systems to access or update selected data.
Scheduled automation
Integrations can run through scheduled cron jobs, queues or background processes when real-time updates are unnecessary.
Webhook processing
We can receive and process event notifications when an order, payment, customer or other record changes.
Error logging and recovery
Important integrations should record failures clearly and support safe retries rather than silently losing data.
How our API integration process works
1. Define the business outcome
We begin with the result you need rather than the technology alone. This may be faster order processing, accurate stock, fewer spreadsheets or better reporting.
2. Review the systems and documentation
We examine the available API documentation, authentication method, data formats, limits and your current website or application.
3. Map the data and workflow
We establish which information moves between the systems, how fields correspond and which system should be treated as the authoritative source.
4. Build and test the integration
The connection is developed and tested using suitable sample data, development environments or API sandbox facilities where available.
5. Deploy with monitoring
After deployment, logs and initial results are reviewed to confirm that requests, updates and scheduled processes are behaving correctly.
6. Maintain and improve
Third-party APIs can change. Ongoing support can cover API updates, new fields, altered workflows and investigation of failed requests.
Reliability, security and data protection
API integrations often handle commercially sensitive information. The integration should therefore be designed with controlled access, careful validation and useful operational records.
Depending on the project, this can include:
- Secure storage of API credentials and tokens
- Authentication and permission controls
- Validation of incoming and outgoing data
- Protection against duplicate processing
- Request and error logging
- Retry handling for temporary failures
- Rate-limit management
- Separation of test and live environments
- Retention of only the data required for the workflow
API integration for ecommerce businesses
Ecommerce businesses commonly operate across several platforms at once. Products may come from suppliers, sales may occur through multiple marketplaces and stock may need to remain consistent across every channel.
API integration can help reduce the manual effort involved in:
- Creating and updating marketplace listings
- Synchronising product prices
- Updating stock quantities
- Retrieving new orders
- Sending orders to fulfilment providers
- Updating tracking information
- Importing commissions and transaction details
- Producing consolidated sales reports
We can also combine API access with supplier feeds, database imports and controlled data extraction where technically appropriate and permitted.
Businesses already using WordPress or WooCommerce can also review our WordPress maintenance plans for ongoing website support outside the integration project.
When an API integration may not be possible
Not every service provides a suitable API, and access to an API does not automatically mean every desired action is permitted.
Before work begins, we may need to confirm:
- Whether the platform provides an API for the required function
- Whether your account has access to that API
- Whether the API permits commercial use
- Whether sufficient documentation is available
- Whether the required data can legally and contractually be transferred
- Whether usage limits are suitable for the expected volume
- Whether additional platform or licence fees apply
Where no suitable API exists, we can discuss permitted alternatives such as scheduled file imports, exports or other supported integration methods.
API integration pricing
API projects vary considerably. A small connection with clear documentation may require only a limited amount of work, while a multi-system integration may require discovery, development, testing and ongoing monitoring.
The price normally depends on:
- The number of systems being connected
- The quality of the API documentation
- The authentication method
- The number of data types and fields involved
- Whether updates are scheduled or real time
- The volume of requests and records
- Error-handling and reporting requirements
- The condition of the existing website or application
- Testing and deployment requirements
Small integration-related tasks may sometimes be handled through an active website support plan. Larger API, marketplace, automation and product-feed projects are scoped separately after the systems and requirements have been reviewed.
Frequently asked questions
Can you integrate an API with an existing website?
Yes. Most API projects involve an existing website or application. We first review its technology, database and current workflow before recommending an implementation.
Can you work with WordPress and WooCommerce APIs?
Yes. We can work with WordPress and WooCommerce alongside supplier, marketplace, payment, CRM and other third-party APIs.
Can you connect a legacy PHP application?
Often, yes. The existing application must first be reviewed to determine how it stores data, handles authentication and can safely communicate with the external API.
Do you provide custom API development?
We can develop controlled API endpoints or integration components for existing PHP-based systems where the project requirements and security model are suitable.
What happens when the external API is unavailable?
A well-designed integration should log the failure and, where appropriate, retry the request safely rather than losing or duplicating information.
How do I choose an API integration service provider?
Look for practical experience with your type of system, clear handling of errors and security, realistic explanations of limitations and a plan for maintaining the integration after launch.
How long does an API integration take?
It depends on the API, the condition of the existing system and the complexity of the workflow. We review the documentation and requirements before estimating the work.
Can you maintain an integration after it is launched?
Yes. Ongoing support can cover monitoring, error investigation, changes to third-party APIs and extensions to the existing workflow.
Discuss your API integration project
Describe the systems you need to connect, the information that should move between them and the manual work you are trying to replace.
We will review the technical requirements and recommend a practical next step, whether that is a small integration, a staged automation project or an initial review of the existing application.
