# Request a file upload

POST https://api.yunojuno.com/file_uploads/
Content-Type: application/json

Request a signed URL to upload a file.

Create a file upload record and obtain a signed URL for direct PUT upload to S3. Different purposes accept different file types (e.g. CSV, XLSX).

Reference: https://docs.yunojuno.com/client-api/file-uploads/create

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Body (application/json)

This endpoint expects a RequestAPIFileUpload.

- `purpose` (enum, required) — * `BULK_PROJECT_UPSERT` - Bulk Project Upsert
  - Allowed values: `BULK_PROJECT_UPSERT`
- `filename` (string, required)
- `mime_type` (string, required)

## Response

### 201

- `data` (APIFileUpload, required) — The API file upload object. This object represents a file that has been uploaded via the Public API. Files can be used for various purposes such as bulk data imports.

## Types

### APIFileUpload

The API file upload object. This object represents a file that has been uploaded via the Public API. Files can be used for various purposes such as bulk data imports.

- `api_file_upload_id` (string, required)
- `purpose` (string, required)
- `filename` (string, required)
- `mime_type` (string, required)
- `state` (string, required)
- `upload_url` (string, required, nullable) — Return the pre-signed S3 upload URL for the file. If the object is awaiting upload, it will generate a presigned S3 URL with short expiry allowing the client to start the upload within that time period. If the object is not awaiting upload, it will return nothing as the upload has occurred already.
