Sending A large attachment using the Microsoft Graph API

I have a big file that needs to be uploaded to azure. I've been using: https://learn.microsoft.com/en-us/graph/api/attachment-createuploadsession?view=graph-rest-1.0&tabs=http their API to Create a draft e, upload session. But I need to split the file into chunks of binary data to sent them into put requests on the session. i've tried using base64 but this does not work. Is there a way to send the binary content of splitfile via put requests?

Hello Luuk,

Do not use the base64 string. When you send the file contents as is, it should work.

Headers -

1. Content-Type : 'application/octet-stream'

2. Content-Range : 'bytes 0-{content byte}' (you will need to calculate the content range)

In the Request, pass the file as - "$FileDocument/Contents"

Hope this helps.

Regards,

Niraj
