Query Regarding uploading the file into Sharepoint through REST API

[Akansh Bhatnagar]

Hello ,

We have a requirement  to upload the flat file to a SharePoint site through a Middleware platform-as-a-service using REST API. I have Client ID and Client Secret for O365 where we have to upload.

As confirmed by team, App is already registered on SPO. However, we need guidance on the mechanism to invoke the SP and upload the file. If anyone in this group has an idea, request you to please revert with your thoughts on the the approach to be followed in this regards.

Thanks in advance.
