What is box?<\/h2>\n\n\n\n

Box is a cloud-based service that allows users to securely store, access, share, and collaborate on files across devices.<\/p>\n\n\n\n

Box also offers an open platform with APIs and SDKs, known as the Box Platform, that developers can use for a variety of purposes.<\/p>\n\n\n\n

Our main purpose is to upload a file in Box using boxr<\/a> gem.<\/p>\n\n\n\n

How to integrate box?<\/h3>\n\n\n\n

First of all, we need to create one account and an application on Box platform<\/a>.<\/p>\n\n\n\n

Sign up for a Box Developer Account<\/a>.<\/h4>\n\n\n\n
\"Box<\/figure><\/div>\n\n\n\n

Create a new application by clicking My Apps<\/b> from left side panel in developers console<\/a>.<\/h4>\n\n\n\n
\"Create<\/figure><\/div>\n\n\n\n

Select Standard OAuth 2.0 (User Authentication) for the new application.<\/h4>\n\n\n\n
\"Box<\/figure><\/div>\n\n\n\n

After creating the application in box account, it will redirect you to application’s configuration page having Developer Token, Client ID and Client Secret.<\/b> For one time authentication of our application, we need to set Redirect URI.<\/b> This is the URL of our Rails Application (Must be secure). Set URI like,<\/p>\n\n\n\n

https:\/\/90e9452e.ngrok.io\/token_catcher<\/code><\/p><\/blockquote>\n\n\n\n

Now, install boxr gem<\/a> in our rails application and create one table to store access token and refresh token of a box for future use as box’s developer token (access token) expires in an hour.<\/p>\n\n\n\n

In Rails console, run the following commands.<\/p>\n\n\n\n

BOX_CLIENT_ID=YOUR CLIENT ID
\nBOX_CLIENT_SECRET=YOUR CLIENT SECRET
\nrequire 'boxr'
\nrequire 'dotenv'
\nDotenv.load(\".\/.envoauth\")
\noauth_url = Boxr::oauth_url(URI.encode_www_form_component('1233'))<\/code><\/p><\/blockquote>\n\n\n\n

Now redirect to oauth_url<\/i><\/code> (pass client Id at the end of url if not present). And click on Grant Access<\/b><\/i><\/code> button, it will redirect to your token_catcher<\/i><\/code> method.<\/p>\n\n\n\n

Below is the code snippet of token_catcher<\/i> method.
