Hello friends, today are going to discuss DropBox Integration with Apex Salesforce. We all heard about the DropBox or store and share files. Those are the things Dropbox provided. Also, We can connect DropBox to Salesforce via Apex Rest API. So we easily upload and fetch files in salesforce.
With Dropbox for Salesforce, you always have access to the latest content. There are already App Exchange App which is a free Link. You can install this and work with files/folders.
Also, check this: What Is Named Credentials, AuthProvider & Use In Apex Salesforce
Highlights Point:
- Use Http callout in Apex Class
- For Authenication we use Outh 2.0 and get access token.
- Use Refresh token for get access token.
- Use Json Parser for parse the json data get in response.
- Show error on any error in callout
Step:1 First we create an Account in DropBox click here, this is the developer link.
click App console and create an account
Step 2: Create a connected app so we can do further processes. click this to create an app.
Step 3: In this step, we will set up app. check below image.
Key Required Fields:
- redirect Url, here you can vf page url
- set scope read write files and folder
- you can setup you team here.
Code Samples :
Step 1: In this step, we will create an Apex Class for Post and Get HTTP Callout to DropBox.
Create methods like create a folder, delete a folder, upload files & get Access Token in class.

Step 2: In this step, we will create a Visualforce page. On this page, we will first authorize so URL redirect to dropbox auth and after auth, it will automatically come back to the Visualforce page with code parameter in URL.
After this, we Post this code with some required parameters because it access token get by grant_type=authorization_code.
