## WhatsApp error: session has expired

This error occurs when your Facebook access token has expired and needs to be refreshed through reauthorization.

## Error Message

> "Error validating access token: Session has expired. The current time is..."

## Why This Happens

Facebook access tokens have expiration periods for security reasons. This error occurs when:

- Your Facebook session has naturally expired
- You logged out of Facebook on another device
- Facebook's security systems required a session refresh
- The admin account password was changed
- Two-factor authentication was updated

## How to fix this error

### Reauthorize with Facebook

\1. Go to Settings > Channels > WhatsApp

\2. Click Reauthorize

\3. Click Continue with Facebook

\4. Log in with the account that has Meta admin/full control access

\5. Complete any security verification if prompted

\6. Grant all requested permissions

Once complete, your WhatsApp Business API connection will have a fresh access token.

## Prevention Tips

- Use a Facebook account with two-factor authentication enabled
- Avoid logging out of Facebook on the admin device
- Check your WhatsApp channel status regularly
- Set up a reminder to check connection status monthly
