In case if Inbound Sync does not work as expected and does not produce any sync events, it might be handy to check following steps.

1. It is important to remember that inbound sync is executed asynchronously. So it might take some time to run (few minutes)
2. Is Service Provider authorised and connection still valid? Can be checked on Service Provider page
3. Is the Inbound Sync Scheduled? Check on Service Provider Level or in [https://upperdeck.atlassian.net/wiki/spaces/FBDOCS/pages/2078310832](https://upperdeck.atlassian.net/wiki/spaces/FBDOCS/pages/2078310832)
  
4. Is Object Mapping Correct?
  1. Is object mapping active (checkbox on mapping)?
  2. Is it “Valid” per FlexConnect validation?
  3. Is the Operation Type correct? For example, if it is Insert, and record is updated - sync will not fire.
  4. Does updated/inserted record comply with filter criteria?
    1. for Inbound Sync, it should be a “external server filtering” style like OData.
    2. for Inbound Sync, client-side filtering should be a Formula field style filter criteria
    3. for Outbound Sync, it should be a SOQL - style filter criteria
  5. Is there an active trigger on account object?
5. Are there any audit trails? Especially with errors? If there are audit trails – it means that sync is scheduled and “tries” to do something, but fails due to either updating records on salesforce side issue, incorrect configuration OR external service not accessible  
For most common error - check [https://upperdeck.atlassian.net/wiki/spaces/FBDOCS/pages/2078310797](https://upperdeck.atlassian.net/wiki/spaces/FBDOCS/pages/2078310797)
6. Are there any errors in  Setup > Jobs > Apex Jobs, related to apex classes **FBCONNECT**.**cls_FBInboundBatchProcess** or **cls_FBInboundBatchProcess**.
  1. In case of an error, it will be displayed on this page.
  2. Make sure that the user that scheduled inbound sync job is active, otherwise sync will not occur
