What is Application Programming Interfaces Glossary?
An Application Programming Interface (API) acts as a messenger, allowing different software systems to communicate effectively. This Application Programming Interfaces Glossary is designed to demystify the key terminology you'll encounter. Grasping these software development terms is vital for anyone working with web services or system integration. Familiarizing yourself with this Application Programming Interfaces Glossary is a key step for developers and tech enthusiasts. Understanding the terms in this Application Programming Interfaces Glossary is fundamental for grasping how software components interact. Let's explore some key API terms you'll find in any comprehensive Application Programming Interfaces Glossary.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| API | Noun | A set of rules and protocols allowing software applications to communicate and exchange data. | Our mobile app uses an API to fetch weather data from an external service. |
| Endpoint | Noun | A specific URL where an API can be accessed by a client to perform an operation. | To get user details, you need to send a request to the /users/{id}endpoint. |
| Request | Noun/Verb | A message sent by a client to an API server asking for data or to perform an action. | The client requests the latest articles by calling the /articles endpoint. |
| Response | Noun | A message sent back by the API server to the client, containing data or status of an operation. | The server sent a successful response with the requested user data in JSON format. |
| JSON | Noun | (JavaScript Object Notation) A lightweight data-interchange format, easy for humans and machines. | Most modern APIs return data in JSON format due to its simplicity and readability. |
| XML | Noun | (eXtensible Markup Language) A markup language for storing and transporting data, often used in older APIs. | Some legacy systems still use XML for their API data exchange. |
| Authentication | Noun | The process of verifying the identity of a client or user attempting to access an API. | Authentication is required before you can access sensitive data through the API. |
| Authorization | Noun | The process of granting or denying access to specific API resources based on authenticated identity. | Even after authentication, authorization checks ensure you only access resources you're permitted to. |
| API Key | Noun | A unique code passed to an API to identify the calling application or user, for authentication and tracking. | You must include your API Key in the header of every request you make. |
| REST | Noun | (Representational State Transfer) An architectural style for designing networked applications, using HTTP. | Many web services are designed as REST APIs because they are stateless and scalable. Read more about REST. |
| SOAP | Noun | (Simple Object Access Protocol) A protocol for exchanging structured information in web services, often using XML. | SOAP APIs are generally more rigid than REST APIs and have a stricter contract. |
| HTTP Methods | Noun | Standard request methods (GET, POST, PUT, DELETE) defining actions on resources. | Use HTTP Methods like GET to retrieve data and POST to submit new data. |
| Rate Limiting | Noun | A control mechanism to limit the number of API requests a client can make in a time period. | To prevent abuse, the API implements rate limiting of 100 requests per minute. |
| SDK | Noun | (Software Development Kit) A set of tools to help developers integrate with an API more easily. | The company provides an SDK in several programming languages to simplify API integration. |
| Webhook | Noun | An automated message (payload) sent from an app to a unique URL when something happens. | We set up a webhook to receive notifications whenever a new order is placed. |
Learning these core components from the Application Programming Interfaces Glossary provides a solid foundation. These API terms are frequently used in technical discussions and documentation.

Common Phrases Used
Beyond individual terms from the Application Programming Interfaces Glossary, certain phrases are common when discussing APIs. Understanding these expressions will help you communicate more effectively about API integration, software API guides, and development projects. These common phrases are part of the everyday language for software developers.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Call an API | To send a request to an API endpoint to trigger an operation or retrieve data. | We need to call an API from the weather service to display the current temperature. |
| Expose an API | To make an API's functionalities available for other developers, services, or applications to use. | The new microservice will expose an API for managing user profiles. |
| Consume an API | For a client application to use or interact with an API provided by another service or system. | Our front-end application will consume an API provided by the back-end to display data. |
| API Integration | The process of connecting different software applications or systems so they can share data via their APIs. | Successful API integration between the CRM and marketing platform streamlined our workflow. |
| Third-party API | An API provided by an external service or company, not built in-house. | We use a third-party API for payment processing to ensure security and compliance. |
| API Documentation | Detailed information, guides, and specifications on how to use and integrate with a specific API. | Always read the API documentation carefully before you start coding the integration. |
| Breaking Changes (in an API) | Updates or modifications to an API that are not backward-compatible, potentially causing issues for existing clients. | The new API version includes breaking changes, so we'll need to update our application code. |
