access to object for external services in version 7.15.2

Dear Fulgen, 

The object name is External Access in the object permissions http://prntscr.com/qgcpjf If you are talking about missing tab in the advanced settings, you can use the operation permission CanUseExternalAccess to add the user who is allowed to access the external services http://prntscr.com/qkdszk and after that select the required permissions for him in the object permissions.

Best regards,

Dean
