Hey Bert,
The short answer first:
If you use our API or SDK to build an application for your firm, your meetings will have a Zoom logo/watermark(saying “powered by Zoom”). If you want to remove the Zoom logo/watermark and/or add your own logo, you can discuss business and licensing with the Zoom team AKA white-labeling.
Detailed answer:
You can use the APIs to build your own web application (or web portal) for the following: user provisioning, manage meetings/webinars/groups/recordings, build dashboards etc.
With our SDKs, you can embed zoom core in your own app - since Zoom runs within the context of your app, our logs will not be visible except for a watermark we show inside the meeting window.
Feel free to let us know if you have a specific business case. If you are looking for creating your own domain (such as your-business-name.com) for meetings, then we have an option to build out a complete private cloud infrastructure which is an expensive option.
Best,
Ammar
