We are embedding our react native mobile app as an iFrame into Salesforce: to allow our app to be an iFrame inside of Salesforce versus a standalone io/sandroid app.

However when trying to call Watson Speech to text api (a service we use in our app) that call fails when it’s from the iFrame in Salesforce mobile.

When you do it from an iFrame in Salesforce (in your browser, not salesforce  mobile) it works perfectly fine.

Is their some security or permission measure preventing an iFrame in salesforce mobile from calling a 3rd party API?
