To link your Facebook account to your Bukas profile, you'll need to get your unique Facebook URL from your profile. Below are the steps to get the URL using a desktop browser or the mobile Facebook app.

If you are using Facebook on a desktop browser:

1. Login to your Facebook account.
2. From the homepage, click your profile.
3. On the address bar of your browser, highlight the complete Facebook URL (should look like this: www.facebook.com/your_fb_id), right click the highlighted URL and click copy.
4. Go back to your Bukas profile and paste it on the Facebook URL field.

If you are using the Facebook App on a mobile phone:

1. Open your Facebook app and login to your Facebook account.
2. From the homepage, click the menu icon on the upper right (looks like three horizontal lines)
3. Click your profile photo or "See your profile" under your name.
4. Click the "Profile Settings" tab (looks like three dots).
5. Scroll down to "Your Profile Link" and click "Copy Link" to copy your complete Facebook profile (should look like this: www.facebook.com/your_fb_id).
6. Go back to your Bukas profile and paste it on the Facebook URL field.

Please take note that this step is only optional.
