Hello,
Thank you for reaching out. With regards to your concern, Express campaigns are not supported in the AdWords API. The creation and modifications of these campaigns will need to be done via the Google Ads UI. Please refer to this blog post for more details related to this. For your other concern, please refer to this guide for creating the Display Smart Campaigns via API by following the process demonstrated in the Add campaigns code example, but with the following changes listed in the guide and let me know if you are still having any issues.
