Here's how an API typically works:
Request →Processing→Response
1. Request: An application sends a request to the API, specifying what action it wants to perform or what data it needs.
2. Processing: The API processes the request, checks for authorization and validity, and performs any necessary operations.
3. Response: After processing the request, the API sends back a response to the application. This response can include the requested data or confirmation of the action performed.
APIs can be used for various purposes. They play a crucial role in enabling software systems to work together seamlessly and efficiently.

There are four different types of APIs commonly used in web services: public, partner, private and composite. In this context, the API "type" indicates the intended scope of use.

Developers often use RESTful APIs, SOAP APIs, GraphQL APIs, and Webhooks to interact with various services and platforms.

API keys and tokens are unique identifiers that grant access to the API. They are used for authentication and authorization purposes, ensuring that only authorised users can access the API.

Yes, BankU offers sandbox environments or test endpoints where you can experiment with the API functionalities without affecting production data.
