In order for developers to build feature for users to upload videos directly to Vimeo, account owner needs to create a 'developer app' that comes with Personal Access Token and Secret Keys (we usually just call all these "API Keys"), and pass that to programmers.

Vimeo also requires owner to specifically request for permission to do direct video upload, this request might take up to 5 days for approval, so please prepare it as early as possible.

Note: For direct video upload, the vimeo account needs to be of Pro, Business, Premium or Enterprise tier

Steps

1. Visit https://developer.vimeo.com/apps/new
2. Click 'Create An App'
3. Fill in App name and description
