API (Application Programming Interface) is the core of any modern infrastructure from the web to mobile, from ERP to CRM. APIs play a very major role.
API’s role is increasing day by day even modern web infrastructure is heading more towards the headless architecture and microservices architecture.
The headless system is also useful for building PWA apps and multichannel apps. For example, if you are running your PWA Magento website and mobile apps. The same API is helpful for web frontend and native mobile app development.
Microservices are small independent services and loosely coupled. Each service is responsible for one business logic development.
If you are building an eCommerce system built on micro-services then it is possible that for API generation you are using PHP. But for notification and order generation you are using Node.js. Also for the search, you are using elastic.
It is not mandatory that the complete tech stack should be based on one server-side technology. Unlike the monolithic system where the code base and stack is the same for all business services.
Modern APIs development is based on two protocols:
- SOAP (Simple Object Access Protocol)
- REST (Representational State Transfer)
REST-based APIs are more popular nowadays. Which are supported by HTTP standard, that means it can be fetched and managed by URL and return JSON which is easy to render on any interface – web or mobile.
All of our native mobile applications and headless development uses REST-based API’s. Also not limited to those are using REST API’s in web/eCommerce development and PIM development as well.
GraphQL – is another API query language nowadays which is getting popular very rapidly. GraphQL is useful for large applications and especially in headless development.
Role of API
API role is enormous no modern tech stack is possible without API. You can find various examples of APIs in every day, for example:
- Payment gateways
- Shipping methods
- SMS gateways
- Logistics API integration
- Multi-channel integration like eBay, Amazon integration
- Various services integration like Google Map and many more.
API’s are everywhere. It is impossible to list all the usage of APIs.
