Once your client starts a paid session with you (from within your website), you’ll hear Consolto’s website ringing on your computer, with a note that you need to confirm or decline the call. Once you accept the call, your client will be asked to pay via Paypal or Stripe, if the option of paying is enabled in your “widget center” (can be found on the back office). After the payment is processed, the video call will start from both your and your client's side.
