This page includes a sample prompt you can use as a starting point when building a Retell agent with Sympana Connector. Use these examples as reference material, not as a final copy-and-paste prompt. Every business has different calendars, workflows, compliance requirements, qualification rules, and data fields. Because of that, you should always adapt the examples to match your exact use case.

​
How to use this page

Use these examples to:
  • understand what each Sympana function is supposed to do
  • see how prompts can instruct an agent to call functions correctly
  • build a first draft faster
Do not assume the examples are production-ready without editing.
