How does API Integration work?
An API specifies how different software components should interact with each other. It defines a set of rules, protocols, and data formats for requesting and exchanging information between software applications. APIs can be RESTful (Representational State Transfer) or use other communication protocols like SOAP (Simple Object Access Protocol).
Types of API Integration
API integration can be categorized into several types based on the integration approach:
- Point-to-Point Integration: In this approach, APIs are integrated directly between two systems, creating a dedicated connection for data exchange. While simple to implement, this approach can become complex and difficult to manage as the number of integrations increases.
- Hub-and-Spoke Integration: This approach involves a central integration hub that connects multiple systems through APIs. The hub acts as a mediator, handling the data transformation and routing between systems. This approach simplifies management and allows for scalability.
- Real-time API Integration: Real-time integration involves the immediate exchange of data between systems as events occur. This enables real-time synchronization and ensures that the connected systems are always up to date.
- Batch API Integration: Batch integration involves exchanging data in batches at scheduled intervals. This approach is suitable for scenarios where real-time synchronization is not required, and data can be processed in batches.
API authentication and authorization
API integration requires proper authentication and authorization mechanisms to ensure secure data exchange between systems. This typically involves using API keys, access tokens, or other authentication methods to validate the identity of the requesting application or user. Authorization controls are implemented to restrict access to specific APIs and data based on user roles and permissions.
Common Use Cases of API Integration
API integration can be used across various business functions. Here are some common use cases and API Integration examples:
ERP integration
APIs help connect business applications to the Enterprise Resource Planning or ERP tool, sometimes via an ERP Integration Platform.
This helps streamline the flow of real-time data between the ERP and tools such as CRM, PIM, EDI databases, ecommerce platforms, marketing automation tools, and more.
