Listening: Technical API Demo to Developer Audience

"For simplicity" is a common demo narration qualifier. The presenter is transparently explaining a deliberate choice — using a simpler tool than production code to make the demo clearer and faster to follow.

Why presenters use curl in API demos:

• curl is universal — every developer knows it
• It shows the raw HTTP request without SDK magic hiding the details
• It's fast to set up during a live demo

Common live demo narration qualifiers:

• "for simplicity" — I'm using a simplified approach; real usage may differ
• "in a real project you'd" — signalling what production usage looks like
• "I'll skip [X] for now" — deliberately omitting something to keep focus
• "bear with me" — asking the audience to be patient during setup or a slow step

Hardcoding = writing literal values directly in code instead of reading them from variables, configuration, environment, or user input.

Why the presenter mentions it: In a live demo, hardcoded values are common (they make demos simpler and more predictable). The presenter transparently acknowledges "obviously you'd pull these from your context" to prevent the audience from thinking this is the recommended approach.

Hardcoding vocabulary in demo narration:

• "I'm hardcoding X here" = using a fixed literal value for demo purposes
• "in production you'd read this from [env/config/DB]" = the real approach
• "obviously / naturally / of course" = signals the audience already understands this is simplified

201 Created = HTTP status code indicating a resource was successfully created. A successful POST to a payments API returns 201 (not 200).

"Follow up async" (asynchronously) = respond after the call, not in real time during the session. The presenter is managing Q&A expectations — letting the audience know that questions not answered live will still be addressed, just not right now.

Async communication in engineering contexts: "Async" is borrowed from programming (asynchronous) and used colloquially to mean "not at the same time / not requiring an immediate live response."

Common Q&A management phrases in tech demos:

• "Happy to take questions" — friendly, open invitation for questions
• "drop it in the chat" — submit your question via the chat rather than verbally
• "follow up async" — I'll answer this after the call
• "let me park that" — noting the question, will address later
• "great question — let me get back to you on that" — diplomatic deferral
