Payment processing refers to the steps taken to complete a financial transaction when a customer pays for goods or services using a card or digital method. It involves securely transferring payment information from the customer to the merchant, and then to the bank or payment provider. The process ensures that money moves from the customer’s…
Instant messaging is a way for people to send and receive text messages in real time using computers, smartphones, or other devices. It allows users to have conversations quickly without waiting for emails or phone calls. Many instant messaging services also support sending images, videos, and files, as well as making voice or video calls.
API-First Architecture is a method of designing software where the application programming interface (API) is defined before any other part of the system. This approach makes the API the central part of the development process, ensuring that all services and user interfaces interact with the same set of rules and data. By focusing on the…
An Enterprise Service Bus, or ESB, is a software system that helps different applications within a company communicate and share data. It acts as a central hub, allowing various programs to connect and exchange information even if they are built on different technologies. By using an ESB, organisations can integrate their systems more easily, reducing…
Microservices communication patterns are the methods and rules used for different microservices to interact and exchange information within a distributed system. These patterns help ensure that services can communicate reliably, efficiently and securely, even when they are built and deployed independently. Common patterns include synchronous communication like HTTP APIs and asynchronous communication using messaging queues…
Collaboration tool integration is the process of connecting different digital tools used for teamwork, such as messaging apps, file sharing platforms, and project management software, so they work smoothly together. This integration helps information flow easily between different systems, reducing the need to switch between apps or enter the same data multiple times. As a…
OpenID Connect is a simple identity layer built on top of the OAuth 2.0 protocol. It allows users to use a single set of login details to access multiple websites and applications, providing a secure and convenient way to prove who they are. This system helps websites and apps avoid managing passwords directly, instead relying…
OAuth 2.1 is an update to the OAuth 2.0 protocol, designed to make online authentication and authorisation safer and easier to implement. It simplifies how apps and services securely grant users access to resources without sharing passwords, by clarifying and consolidating security best practices. OAuth 2.1 removes outdated features, mandates the use of secure flows,…
Stateless clients are systems or applications that do not keep track of previous interactions or sessions with a server. Each request made by a stateless client contains all the information needed for the server to understand and process it, without relying on stored context from earlier exchanges. This approach allows for simpler, more scalable systems,…
A Secure API Gateway is a tool or service that acts as a checkpoint between users and backend services, filtering and managing all requests to APIs. It helps protect sensitive data by enforcing security policies, authentication, and rate limiting, ensuring only authorised users can access certain resources. Secure API Gateways also provide monitoring and logging…
