How can I enable resumable file transfers using the Google Drive API?

Using the Drive API, I encounter issues with resumable uploads: either 404 errors or empty file creation without a Location header. For example, try this revised code snippet:

POST https://api.driveapp.com/v3/files?resumable=true
Headers:
  Accept: application/json
  Auth: Bearer TOKEN123
  X-File-Size: 15
  X-File-Format: text/csv

{
  "type": "text/csv",
  "containers": [{"container_id": "rootFolder"}],
  "name": "upload.csv"
}

I recently worked with the same API and encountered similar challenges with resumable uploads. My experience taught me that it is important to verify that the endpoint you use corresponds to the one documented by Google. Sometimes custom URLs can lead to unexpected behavior like missing headers or faulty error responses. I eventually resolved the issue by carefully comparing the required settings and ensuring that all authentication details were correctly provided. Also, working with a REST client tool helped validate the API’s responses to your requests.

hey i ran into similar probs. check you use https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable not your custom url, and make sure you include right auth headers. hope it helps, sometimes tiny typos cause big issues.
