obtain item-id for microsoft graph api - sharepoint

Question

I am trying to figure out how to obtain an "item-id" for a file in a sharepoint site for microsoft graph API.
Microsoft documentation: https://learn.microsoft.com/en-us/graph/api/driveitem-get?view=graph-rest-1.0&tabs=http
Here is what I tried for far:
Tried using https://developer.microsoft.com/en-us/graph/graph-explorer to guess the api link that will let me download the file I want.
I first tried to get the sharepointsite like so:
https://graph.microsoft.com/v1.0/sites/omidtechnfr.sharepoint.com:/sites/delploy
That worked:
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites/$entity",
"createdDateTime": "2021-07-15T21:02:02.78Z",
"description": "delploy",
"id": "omidtechnfr.sharepoint.com,5e03397e-03b0-4d92-9658-f9163f0131b3,1d9f21da-4d74-45db-b5d4-e4a7f7f278a1",
"lastModifiedDateTime": "2021-07-17T02:16:39Z",
"name": "delploy",
"webUrl": "https://omidtechnfr.sharepoint.com/sites/delploy",
"displayName": "delploy",
"root": {},
"siteCollection": {
"hostname": "omidtechnfr.sharepoint.com"
}
}
So then I tried using what I ASSUME is the item-id for the SharePoint site delploy to try and get more information out of the site so I can try to find the item-id for the file I want to download:
https://graph.microsoft.com/v1.0/sites/5e03397e-03b0-4d92-9658-f9163f0131b3/drive/
And I got back some result but it doesn't so the item-id for me to do anything with it:
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#drives/$entity",
"createdDateTime": "2021-07-11T05:16:50Z",
"description": "",
"id": "b!fjkDXrADkk2WWPkWPwExs9ohnx10TdtFtdTkp_fyeKF_K1_Z49FFSbzXVFRA5GKa",
"lastModifiedDateTime": "2021-07-16T18:32:35Z",
"name": "Documents",
"webUrl": "https://omidtechnfr.sharepoint.com/sites/delploy/Shared%20Documents",
"driveType": "documentLibrary",
"createdBy": {
"user": {
"displayName": "System Account"
}
}
At this point I started to get desperate and a little angry. So I tried to just download the file from sharepoint and assume that the characters at the end of the download link was the item-id but that didn't work either:
download link:
https://omidtechnfr.sharepoint.com/sites/delploy/_layouts/15/download.aspx?UniqueId=25e2fd4f%2Deb32%2D43ac%2D9141%2Dfa47a610a27c
Used https://www.urldecoder.org/ to decode what I am assuming is the item-id for the file I want to download
25e2fd4f-eb32-43ac-9141-fa47a610a27c
Then tried to desperately tack this on to the Microsoft graph api to see what happens:
https://graph.microsoft.com/v1.0/sites/5e03397e-03b0-4d92-9658-f9163f0131b3/drive/items/25e2fd4f-eb32-43ac-9141-fa47a610a27c
and it failed:
{
"error": {
"code": "itemNotFound",
"message": "The resource could not be found.",
"innerError": {
"date": "2021-07-17T14:13:51",
"request-id": "985e2893-5343-47ac-a93c-6629a00c4eb3",
"client-request-id": "73a3b6d0-f1ce-bb51-b126-43f0957d15e3"
}
}
}

Answer 1

You could get the file by the path: https://graph.microsoft.com/v1.0/sites/{site-id}/drive/root:/{item-path}
For example: https://graph.microsoft.com/v1.0/sites/{site-id}/drive/root:/test.docx
If the file is in a folder, it would be like this: https://graph.microsoft.com/v1.0/sites/{site-id}/drive/root:/folder1/test.docx

Answer 2

I used the search site id endpoint GET /sites/{site-id}/drive/root/search(q='{search-text}')
