API & Middleware
API & Middleware
Connecting systems and allowing them to “talk” to each other offers huge advantages in flexibility, efficiency and secure access to information from multiple sources. Secure integration between stand-alone systems and applications is possible using an Application Programming Interface (API).
An API is a software interface that allows interactions between multiple systems. The API sets out the rules for the kinds of calls or requests that can be made, how to make these calls and the data formats that should be used.
Barsbank has vast experience in not only connecting systems through third party API’s, but also writing our own API’s to fit our client’s needs.
We also develop bespoke middleware solutions that can process and manipulate the data being accessed via an API to add value to our clients and their customers.
The API & Middleware Development Process
HOW WE DO IT
1
Understanding Systems & Requirements
Every API and middleware development project begins with understanding the systems that need to communicate, the data that needs to move between them and the business processes the integration must support. We review your existing software, APIs, databases and workflows to identify the most reliable and efficient way to connect your platforms without unnecessary complexity.
2
Integration & Middleware Specification
Once the requirements are understood, we define how the integration will work, what data will be transferred and how each connected system will respond. We can specify REST APIs, middleware services, authentication, data transformation, error handling and the technical infrastructure required, then provide a clear development scope and quotation.
3
Development, Integration & Testing
The API or middleware solution is developed and tested against the agreed specification. We validate data transfer, authentication, system responses, error handling and performance to ensure the connected systems communicate reliably. Development can be iterative or follow a fixed schedule depending on the complexity of the project and the systems involved.
4
Deployment, Monitoring & Review
Once the integration has been deployed, we monitor its performance and review how effectively data is moving between systems. Where required, we can optimise the middleware, add new endpoints, extend integrations or introduce additional functionality as your business processes and software requirements continue to evolve.

FAQS
API development and integration involves creating or connecting software interfaces that allow different applications and business systems to communicate with each other. An API can securely transfer information between websites, databases, CRM systems, accounting software, booking platforms and other applications. Barsbank can develop bespoke APIs or integrate existing third-party APIs to help businesses connect systems, automate processes and reduce manual data transfer.
Middleware is software that sits between different applications or systems and enables them to communicate when a direct connection is not practical. It can receive data from one system, process or transform it and then pass it to another in the required format. Bespoke middleware can be particularly useful when connecting older software, third-party platforms, databases or multiple business systems that were not originally designed to work together.
Barsbank can develop integrations between a wide range of websites, online systems and business applications. Depending on the APIs and technical access available, this can include CRM systems, accounting software, eCommerce platforms, payment providers, booking systems, databases, stock management software, customer portals and other third-party applications. We first assess the systems involved and their available integration options before recommending the most appropriate solution.
Yes. Barsbank can integrate websites and online applications with CRM systems and other business software where suitable APIs or integration methods are available. For example, website enquiries, customer registrations, orders or bookings could be automatically transferred into another business system. This can reduce duplicate data entry, improve accuracy and help information move more efficiently between your website and internal processes.
Yes. Where an existing system needs to exchange information with other applications, Barsbank can assess whether a bespoke API can be developed to provide the required functionality. The API can be designed around the data, actions, authentication requirements and business processes involved. This can provide a structured way for websites, applications and other authorised systems to interact with your existing software.
Middleware can often provide a practical way to connect legacy applications with newer cloud-based platforms without immediately replacing the existing system. The middleware acts as an intermediary, receiving information from one platform and converting or processing it into a format another system can use. The feasibility depends on the technical access available within the legacy software, which Barsbank can investigate during the initial requirements stage.
Yes. API integration can remove many repetitive tasks that would otherwise require employees to manually transfer information between systems. For example, an integration could automatically create customer records, transfer orders, update booking information, synchronise data or trigger actions when something happens in another application. Automating these processes can save time, reduce human error and help different areas of a business work together more efficiently.
Security should be considered throughout API and middleware development. Depending on the systems involved, this can include secure authentication, encrypted HTTPS connections, access controls, validation of incoming data, appropriate permissions, logging and error handling. Barsbank assesses the security requirements of each integration and the authentication methods supported by the systems and third-party APIs involved.
A REST API is a commonly used approach that allows applications to communicate over the web using standard HTTP methods. REST APIs can provide defined endpoints through which authorised applications can request, create, update or remove information. They are widely used to connect websites, mobile applications, cloud platforms and business software because they provide a flexible and standardised approach to exchanging data between systems.
The development time depends on the number of systems involved, the complexity of the data being transferred, the quality of the available APIs and documentation, authentication requirements and the business processes being automated. A relatively simple third-party API integration may be completed considerably faster than bespoke middleware connecting several complex systems. Barsbank assesses the technical requirements before providing a development specification, timescale and quotation.
Yes. APIs and third-party software can change over time, so ongoing monitoring and maintenance can be important for business-critical integrations. Barsbank can provide ongoing support, troubleshoot integration problems and extend existing middleware or APIs as requirements evolve. Additional systems, endpoints, data transfers and automated processes can also be introduced as the business grows.
Barsbank combines more than 25 years of experience in website development and bespoke online systems with experience developing integrations between different applications and business platforms. This means we can look beyond simply connecting two APIs and consider how the integration fits into the wider business process. Our aim is to create reliable API and middleware solutions that reduce manual work, improve the flow of information and allow different business systems to work together more effectively.
