*Since Camel {since}*

*{component-header}*

The Dropbox component allows you to treat
https://www.dropbox.com[Dropbox] remote folders as a producer or
consumer of messages. Using the
https://github.com/dropbox/dropbox-sdk-java[Dropbox Java
Core API], this camel
component has the following features:

* As a consumer, download files and search files by queries
* As a producer, download files, move files between remote directories,
delete files/dir, upload files and search files by queries

In order to work with Dropbox API you need to obtain an *accessToken*,
 *expireIn*, *refreshToken*, *apiKey*, *apiSecret* and a *clientIdentifier.* +
You can refer to the
https://dropbox.tech/developers/migrating-app-permissions-and-access-tokens[Dropbox
documentation] that explains how to get them.

Maven users will need to add the following dependency to their `pom.xml`
for this component:

[source,xml]
----
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-dropbox</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

Upload files on Dropbox.

Works as Camel producer.

Below are listed the options for this operation:

[width="100%",cols="20%,20%,60%",options="header",]
|===
|Property |Mandatory |Description

|`uploadMode` |`true` |add or force this option specifies how a file should be saved on
dropbox: in case of "add" the new file will be renamed if a file with the same
name already exists on dropbox. In case of "force" if a file with the same name already exists on
dropbox, this will be overwritten.

|`localPath` |`false` |Folder or file to upload on Dropbox from the local filesystem.
If this option has been configured then it takes precedence over uploading as a single

|`remotePath` |`false` |Folder destination on Dropbox. If the property is not set, the component
will upload the file on a remote path equal to the local path. With Windows or without an absolute 
localPath you may run into an exception like the following:

Caused by: java.lang.IllegalArgumentException: 'path': bad path: must start with "/": "C:/My/File" +
OR +
Caused by: java.lang.IllegalArgumentException: 'path': bad path: must start with "/": "MyFile" +

=== Samples

[source,java]
----
from("direct:start").to("dropbox://put?accessToken=XXX&clientIdentifier=XXX&expireIn=1000&refreshToken=XXXX"

      +"&apiKey=XXXXX&apiSecret=XXXXXX&uploadMode=add&remotePath=/root/folder2")
   .to("mock:result");
----
