How to logout of Facebook and Gmail with api during native app automation?

I'm automating native iOS app with Appium. Which has scenarios related to connect with facebook or gmail.

As base state, I want to make sure user has logged out of facebook and gmail.

Please let me know if this is possible with api calls?

Thanks & Regards, Vikram

Same issue here.

Workaround: As a precondition, open the safari browser on device and logout. Use SafariLaucher https://github.com/budhash/SafariLauncher, create webapp steps to logout in BeforeClass/Method.
