Hi Chirangee,

There is a learning and certification path:

DataMiner Connector Integration: HTTP Basics - DataMiner Dojo

Scripts & Connectors Developer: HTTP Basics - DataMiner Dojo

Another option is to create a scripted connector:

Kata #18: Creating a scripted connector - DataMiner Dojo

Data Sources | DataMiner Docs

Something that helped me a lot is looking into existing drivers for http devices.
