webhook limit, Are there any API limits when receiving data via webhook? Limits of APIs not related to video creation

I want to use webhooks mainly. When video creation is complete, I need a function to receive notifications via webhooks, etc.

What are the usage restrictions for trial APIs, APIs that are not related to video creation, such as webhooks?

Are there any API limits when receiving data via webhook?

I have a question because there are no API restrictions for non-video creation.
