Hello @JAPNAM SINGH ,
I'm not sure of all the features on the Sharepoint side but if it lets you use HttpClient (in the SPItemEventReceiver.ItemAdded event handler) and invoke an HTTP endpoint, you can a corresponding Function App with an HTTP trigger, and the entire thing should work. It seems to have been done before with Sharepoint Online, in example: SharePoint Remote Event Receivers using Azure Function
Another approach is to use Logic Apps workflow and it might be quicker & simpler to manage:
- Sharepoint Connector has a dozen triggers, one of which is When an item is created.
- Assuming that the event you want is provided by the SP connector, you can then call your function app using the Azure Functions connector.
I hope this helps you to get started, let me know if you have any further questions.
