This API allows us to get a presigned URL for uploading files to Simpplr.
Few points to note:
- The upload_url(presigned URL) in the response should be used with PUT method to upload the file.
- The presigned URL should be invoked with same Bearer token as this API.
- The file_id should be saved for linking with entities via other APIs.
