Mule Integration with Dropbox

1. By Ramakrishna Narkedamilli

2. Overview:
MuleSoft is a popular ESB technology to integrate various on-premise and cloud
applications for data exchange. Dropbox is a cloud storage for personal and business
people. Provides client software for many operating systems to sync with Dropbox
account data. The Mule Dropbox connector allows applications to interact with
Dropbox API to perform various actions.
In this presentation will going to see how to Integrate Mule ESB with Dropbox
account to perform Authorization and create folder actions using Mule ESB Anypoint
Dropbox connector.

3. Prerequisites:
 Dropbox Developer account.
 Dropbox app key and app secret values
 Mule studio with runtime version 3.4+
 Mule Dropbox connector.

4. Dropbox Developer Account Setup:
For this sample purpose, we need Dropbox account. We can sign up for free
at https://dropbox.box.com/

5.  Once account creation done, open the link and click on Create app button
https://www.dropbox.com/developers/apps
 Provide the appropriate values like below and click on Create app button
available at bottom.

6.  Finally note down the APP key and APP secret values and add the Oauth2
call back URL.

7. MULE ESB Flows for Dropbox Integration
The below Mule application is used to create folder under Dropbox account
after performing authorization action using Mule Anypoint Dropbox
connector.

8. Steps to be followed for integrating ‘Dropbox’ with MuleSoft Applications:
 Install the Dropbox Connector in Anypoint Studio
http://repository.mulesoft.org/connectors/releases/3.5

9.  Create a new Anypoint Studio Project and Flow to create new folder.
 Configure the Dropbox global element in global elements section by providing the
App key and App secret values and setup the oauth callback for authorization.

11.  In the flow first add HTTP inbound endpoint to trigger the service.
 Add Dropbox endpoints in the flow for authorization and folder creation
referring to Dropbox global connector.
 In the Second Dropbox endpoint for folder creation enter MEL expression
#[message.inboundProperties.'http.query.params'.foldername] in path
variable to create folder in the Dropbox account rootpath.
 Now at this position we are integrated with Dropbox to perform actions.

12. Running and Testing the Application:
 Right-click on the application  Run  Mule Application.
 Open the browser and hit the url http://localhost:8082?foldername=Mule_POC_Folder
 Service will take the control to Dropbox for authorization and grant the permission
(This below screen will appear if you already logged in authorize it will ask you to
login first then below screen will appear).
 On the successful authorization, folder will be created under Dropbox account and
response will be returned to browser in case of no errors

13. Folder creation Under Dropbox
 Open the Dropbox account, now you’re able to see new folder
“Mule_POC_Folder”
