Best Practices
Best Practices
Out-of-the-Box Behaviors (Summarized):
- Speech pattern: Direct, concise, casual
- Spells out symbols, acronyms, abbreviations, percentages, etc. ($4,000,000 -> “four million dollars”)|
- Asks clarifying questions
- Ends call when objective is complete or voicemail is detected
Prompting Tips:
- Want to easily test out exactly how your agent will behave?
- Aim for less than >2,000 characters where possible.
- Simple, direct prompts are the most predictable and reliable.
- Frame instructions positively:
"Do this"rather than"Don't do this"- Ex. “Keep the conversation casual” rather than “Don’t be too formal”.
- This gives concrete examples of what to do, instead of leaving expected behavior open to interpretation.
Response
string
Can be
success or error.string
A unique identifier for the call (present only if status is
success).{
"status": "success",
"call_id": "9d404c1b-6a23-4426-953a-a52c392ff8f1"
}
