Different types of APIs that can accelerate your business
APIs come in various types, each designed to cater to specific needs and functionalities. Here are different types of APIs that can help your business optimize communication with other external systems.
1. Open APIs (Public APIs)
Open APIs, also known as public or external APIs, are accessible to developers globally. They have minimal authentication and authorization requirements and often limit shared assets. While some are free, others require a subscription fee based on the number of API calls made.
2. Internal APIs (Private APIs)
A first-party or internal API is a set of rules and tools created by a software company or platform for its own use. These private APIs are intended for internal use within an organization. They streamline communication and data sharing among various internal systems and applications.
3. Partner APIs
Partner APIs are shared with specific external partners, allowing them limited access to certain features or data. These APIs enable secure collaboration between your business and trusted partners.
4. Composite APIs
Composite APIs allow developers to bundle multiple API calls or requests into one unified request. In complex scenarios, like microservices architectures, where one task requires data from numerous internal APIs, composite APIs simplify the process significantly.
In this article, we’ll discuss only external aka third-party APIs. Let’s learn everything about third-party APIs from the following sections.
What are third-party APIs?
Third-party APIs (Application Programming Interfaces) are interfaces provided by external organizations or developers that allow software applications to communicate and interact with their services, data, or features. These APIs are called “third-party” because external entities create them.
Usually, independent developers or companies provide third-party APIs, who are not directly involved in the development or distribution of the software being used.
Example: You can sign up with Google to create a new Twitter account. When you click ‘sign up with Google,’ Twitter accesses Google’s API to gather your email, name, and other necessary information for your profile setup. Google Sign-In functions as the third-party API in this process.
Some people face a dilemma when choosing between third-party APIs (external APIs) and first-party APIs (Internal APIs). The following comparison table might help them decide.
Key differences: first vs. third-party APIs
|Aspect||First-party APIs||Third-party APIs|
|Ownership and control||Developed and maintained internally by the platform or service provider.||Developed externally by external entities or companies.|
|Data security||Higher level of trust and assurance due to internal control and oversight.||Relies on the provider’s security practices, necessitating thorough evaluation.|
|Customization||Extensive customization options to allow tailored integration.||Predefined functionalities with limited customization possibilities.|
|Reliability and support||Reliable support, extensive documentation, and dedicated channels.||Reliability varies; depending on the provider’s reputation and track record.|
|Development costs||Potentially higher initial costs, lower ongoing maintenance overhead.||Lower upfront costs; may have recurring fees based on usage or licensing.|
Each type has unique strengths and considerations. Choose wisely to ensure seamless integration and optimal performance for your applications!
How third-party APIs work
Using a third-party API means your application can talk to another service or system. You make requests (like asking for weather data) through specific web addresses (URLs) using a secret code (API key).
The API processes your request and sends back the information in a format like JSON. Your app then uses this data to do things like displaying weather updates.
It’s like ordering food at a restaurant. You don’t go into the kitchen and cook your meal; instead, you order from the menu. The kitchen and the menu act like two separate systems, and the waiter is like an API, the link between them. And, you’re the end user.
