Write SharePoint Online event handler and deploy to new sub site library dynamically

Hi All,

I’m in facing a critical problem with SharePoint Online (aka SharePoint Office 365). Our requirement is to have an event handler for ItemAdding and another for ItemDeleting.

Now- we think that we need to develop a Remote Event Handler for our purpose. Problem seems to be for an event handler, we need to specify the URL of the Site and list. In our case, the new site will be created dynamically (through program) and the library too. So, we need to associate two event handler using code (to the new site url and library). There can be 1000 sub site per site collection in our tenant.

Can any one please suggest how to write such event handler for SharePoint Online and how to deploy that event hander to 1000 of sub site libraries dynamically? The functionality of each eventhandler will remain the same (that is – event method code will remain the same for any document library).

Thanks a lot to all of you whoever tries to help me.

Have a great day and looking forward for your early response.

Warm Regards,
