How Can I Extend Facebook Access Token Validity After Offline Access Deprecation?

Extending Access Token Validity after Offline Access Deprecation

Facebook's deprecation of the offline_access permission has created uncertainty regarding the acquisition of long-lived access tokens.

Specifically, the documentation suggests that server-side OAuth-generated tokens will possess extended validity. However, this does not appear to be the case.

Addressing the Issue

The provided response presents two solutions:

Solution 1: Official Facebook PHP SDK Update (August 14th, 2012)

An updated version of the official Facebook PHP SDK includes a method named setExtendedAccessToken. Calling this method will create a new access token with a 60-day expiration period.

Solution 2: Custom Function

A custom function can be added to the base_facebook.php file in the Facebook class. This function, getExtendedAccessToken, retrieves a refreshed access token with a 60-day validity.

Additional Notes

• Enabling "deprecate offline_access" in the Advanced settings of your Developer App is recommended.
• According to the updated SDK, calling getExtendedAccessToken no longer returns the token explicitly. Instead, it is stored in the persistent data. To retrieve the new token, use the getAccessToken method.
