Which of the following are short commands or shortcuts for commands passed to Amazon DSP to enhance ad line and creative monitoring capabilities externally, without the need to generate multiple third-party tag sets.

Creative macros are short commands or shortcuts embedded directly into ad creatives. When an ad serves, these macros dynamically populate with information like impression timestamps, click IDs, or device details, which can then be passed to external monitoring systems. This eliminates the need for separate third-party impression tags for each data point, streamlining monitoring and reducing latency. Server-to-server integrations are a broader method of data exchange between systems, not specifically a shortcut within creatives for monitoring. Impression tags are a type of third-party tag, which is what creative macros aim to reduce the need for, not a shortcut themselves.
