# Dropbox Export

> Which downloads a platform or HTTP file URL and uploads its bytes to the connected Dropbox account.

This document covers `export_to_dropbox` (display name **Dropbox Export**),
which downloads a platform or HTTP file URL and uploads its bytes to the
connected Dropbox account.

Dropbox is a **native REST integration**, not an MCP or Composio tool.

## Authentication and enablement

The tool uses the **Dropbox** OAuth connector. The access token is injected
through `x-variable-service: "dropbox"` and is not shown as a per-run input.
Dropbox API and content calls use the audited HTTP transport.

Off by default. Enable the tool explicitly for each agent that
needs Dropbox export.

Dropbox Business accounts resolve `root_namespace_id` and send
`Dropbox-API-Path-Root`, preserving legacy uploads into the team space.

## Inputs

Required:

* `file_url`: source file URL, such as a platform storage URL or output from
  another file-producing tool.
* `destination_path`: complete absolute Dropbox path including the file name,
  such as `/Reports/report.csv`.

Optional:

* `conflict_mode`:
  * `autorename` (default): preserve the legacy behavior, keeping both files
    and letting Dropbox choose a unique name.
  * `add`: fail when the destination already exists.
  * `overwrite`: replace the existing file.
* `mime_type`: output MIME type; inferred from the uploaded name when omitted.

Destination paths reject empty, `.`, and `..` components.

## Upload behavior

* Exports are limited to **250 MB**.
* Empty source files are rejected explicitly.
* Files up to 8 MB use Dropbox's simple upload endpoint.
* Larger files use an upload session with 8 MB chunks.
* Read requests may be retried; upload and session mutations are not blindly
  replayed after an ambiguous response.
* Missing destination parent folders are created component by component,
  matching the legacy Dropbox export folder picker.

## Output

The structured result contains `dropbox_id`, `file_name`, `destination_path`,
`revision`, `content_hash`, `mime_type`, `file_size`, `conflict_mode`, and
`completed_at`.

## Errors

* Missing source URL, malformed destination path, or unknown conflict mode
  fails validation before upload.
* Source download, size, Dropbox conflict, and upload-session failures return a
  structured tool error.
* Tokens, paths, response bodies, and file content are never written to logs.
  Errors carry the HTTP status plus, when Dropbox reports one, the union tag or
  the name of a scope the app has not been granted. A missing write scope fails
  as a `400`; grant it in the Dropbox App Console and reconnect the integration.
