Dear Meta Support Team,

I hope this message finds you well. I am writing to seek assistance regarding an issue we are experiencing with our Facebook Ads Marketing API access token. We have encountered an error indicating that "The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons." However, we can confirm that no password changes have been made on our end, leading us to believe this may be an issue with the token itself.

Error Details: Error Message: "The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons." Access Token Type: (User Access Token/Page Access Token) App ID: ****our app id Ad Account ID: **** ad account id Date and Time of Occurrence: June 9, 2024

Given the critical nature of our advertising campaigns, it is imperative for us to understand the root cause of this issue and the best practices to handle it effectively. Could you please provide insights into the following:

Possible Causes: What are the potential reasons for the invalidation of access tokens beyond password changes? Preventive Measures: Are there any best practices or configurations we should follow to prevent such invalidations in the future? Token Renewal: What is the recommended process for renewing tokens to ensure continuous access without interruptions? Security Protocols: Are there any additional security protocols or settings we should be aware of that could influence token validity?

We appreciate your prompt attention to this matter and look forward to your guidance on resolving this issue efficiently. If you require any further information from our side, please do not hesitate to let us know.

Thank you for your support.
