📌 API Keys Summary
API keys are unique codes used to identify and authenticate users or applications that want to access an API. They act as a form of digital identification, allowing an API provider to control who can use their service and how it is used. By requiring an API key, organisations can monitor usage, enforce limits, and help keep their systems secure.
🙋🏻♂️ Explain API Keys Simply
An API key is like a special pass or ticket you need to access a private event. Without the ticket, you are not allowed in, and the organisers can track who attends and how many times they visit. This helps keep things organised and secure.
📅 How Can it be used?
API keys can be used to control and monitor access to your web application’s data or services by external developers.
🗺️ Real World Examples
A weather application uses an API key to access up-to-date weather data from a weather service provider. The key ensures only registered users can get the data and allows the provider to limit the number of requests each user makes.
A payment processing company requires API keys from online shops that want to process transactions through their service. This helps the payment provider verify which shops are making requests and protects against unauthorised access.
✅ FAQ
What is an API key and why do I need one?
An API key is a special code that helps a service know who is using its tools or data. Think of it like a digital pass that lets you access an online resource safely. You need one so that the provider can keep track of how their service is being used and make sure only trusted users can get in.
How does using an API key help keep things secure?
API keys help protect services by making sure only people or apps with permission can access them. If someone tries to use the service without the right key, they will not get in. This helps stop misuse and keeps data safer for everyone.
What happens if someone else gets hold of my API key?
If someone else gets your API key, they could use it to access the service as if they were you. This could lead to unexpected charges or security risks. It is important to keep your key private and let the service provider know straight away if you think it has been exposed.

Chatbot Software
Chatbot software is a computer program designed to simulate conversation with human users, usually through text or voice interactions. It uses rules or artificial intelligence to understand questions and provide responses. Chatbots are often used to automate customer service, provide information, or assist with simple tasks.
Stakeholder Engagement Plan
A Stakeholder Engagement Plan is a document that outlines how a project or organisation will communicate and interact with people or groups affected by its work. It identifies who the stakeholders are, what their interests or concerns may be, and the best ways to involve them in the process. The plan also sets out methods for gathering feedback, addressing issues, and keeping stakeholders informed throughout the project's life.
Self-Attention Mechanisms
Self-attention mechanisms are a method used in artificial intelligence to help a model focus on different parts of an input sequence when making decisions. Instead of treating each word or element as equally important, the mechanism learns which parts of the sequence are most relevant to each other. This allows for better understanding of context and relationships, especially in tasks like language translation or text generation. Self-attention has become a key component in many modern machine learning models, enabling them to process information more efficiently and accurately.
Temporal Difference Learning
Temporal Difference Learning is a method used in machine learning where an agent learns how to make decisions by gradually improving its predictions based on feedback from its environment. It combines ideas from dynamic programming and Monte Carlo methods, allowing learning from incomplete sequences of events. This approach helps the agent adjust its understanding over time, using the difference between expected and actual results to update its future predictions.
Access Role Tracker
An Access Role Tracker is a tool or system that keeps a record of who has permission to access certain resources, files or areas within an organisation. It helps administrators see which employees have specific roles, such as admin, editor or viewer, and ensures that access is given only to those who need it. This system makes it easier to review, update or remove permissions as staff change roles or leave the organisation.
