Generate OAuth keys

Facebook

To generate a Facebook secret key, you need to sign-up for a Facebook account first. Once you have an account, follow these steps:
  1. Open a browser
  2. Visit https://developers.facebook.com/apps
  3. Click on Create New App
  4. Fill-in the App Name
  5. You will be redirected to the Basic settings page
  6. Now copy the App ID value. This is your client ID
  7. Then copy the App Secret value. This is your client secret

Note: The values need to be stored in the spring.properties file (see Part 5).

On my sample app, here's the Basic settings page. I've purposely changed the App ID and App Secret values:


Twitter

To generate a Twitter secret key, you need to sign-up for a Twitter account first. Once you have an account, follow these steps:
  1. Open a browser
  2. Visit https://dev.twitter.com/
  3. Visit the My applications page at https://dev.twitter.com/apps
  4. Click on Create a new application
  5. Fill-in the Name
  6. Fill-in the Description
  7. Fill-in the Website (You will need to invent a fictitious URL)
  8. You will be redirected to the Details tab of your new application
  9. Now copy the Consumer key value. This is your client ID
  10. Then copy the Consumer secret value. This is your client secret

Note: The values need to be stored in the spring.properties file (see Part 5).

On my sample app, here's the Details tab. I've purposely changed the Consumer key and Consumer secret values:
