Sending campaign through API without smart send and with UTM tracking

Hi !

I want to schedule a campaign using an API call in PHP without the smart sending option but with the UTM tracking option and it does not seem to work.

I am able to create and schedule the campaign, but no matter the value I provide for parameters use_smart_sending and add_google_analytics, the first one always ends upTRUE and the second one always FALSE.

Everything else works as expected and I have been able to schedule test mailing to the list I want with the template I want, but impossible to set correctly these 2 parameters.

Any idea of what the problem could be ?

Thanks!
