Where can the JavaScript Tag API documentation be found?

The JavaScript Tag API documentation can be found under "Settings > Web and mobile monitoring > Advanced setup" because this section is specifically designed to provide resources and configurations for web and mobile monitoring setups, including the JavaScript Tag. This is where users can access detailed instructions and options related to monitoring strategies for web applications, including the implementation of the JavaScript Tag for accurately tracking user interactions and performance metrics.

By placing the documentation in this context, users can easily locate relevant resources while setting up or managing their web monitoring solutions, making it a user-friendly experience tailored to those specifically interested in web and mobile tracking capabilities. The other options refer to different settings that do not directly relate to JavaScript tag implementation or documentation, which is why they would not be the appropriate locations for this information.
