API & Integration Development

Seamless connections and limitless possibilities

Few organisations have the luxury of building fully-customised software to meet all of their business needs. In practice, a hybrid mix of off-the-shelf and custom solutions are deployed to meet requirements across multiple business domains. A key challenge is to integrate and orchestrate this mix of solutions to empower and optimise end-to-end business workflows - that is where we come in! Work with us to build your APIs and integration services to seamlessly connect your business together.

Optimise your existing software investments

Your current technical landscape has evolved with your business and represents a significant and long term investment. Make the most of these existing capabilities with APIs and integrations to enable seamless data exchange between different systems and applications, fostering efficient collaboration and improving productivity.

Simplify future development and enable faster time-to-market

The availability of efficient and well-documented APIs, providing access to information and features across your organisation, increases productivity for application developers. This will reduce time-to-market and boost business agility. Easily connect with external systems, partners, and third-party applications to adapt and respond quickly to changing market demands.

Automate business processes

Without integration, it’s common to see processes get siloed into multiple separate applications with overlapping feature sets and subsequent double-handling. Even worse is the risk of these data siloes getting out of sync, leaving fragmented and out-of-date information scattered across the application landscape. By automating processes, businesses can achieve streamlined workflows, eliminate manual data entry, and ensure data consistency across their operations.

What is API and integration services?

As businesses grow, their portfolio of services and their need to connect with third-party providers expand to get the most out of their software and efficiently exchange information.

Integration layers and APIs allow different software applications (e.g. CRM like Salesforce, Finance system like SAP, HR system like Workday, etc.) to communicate and interact with each other. They focus on getting services to work together - integrating different systems, enabling real-time data sharing, and building new applications on top of existing ones.

The Azenix team has in-depth capabilities and a breadth of experience to work alongside your business to plan and deliver integration and API projects across your cloud and on-premises workloads. Specialising in .NET development and Azure Cloud, but with a wide range of programming language skills, we leverage best practices from Microsoft and across the industry.
