Simple
Configure a single TwiML verb via the node UI. Common options are exposed as fields.
Advanced
Write raw TwiML in a syntax-highlighted editor, or provide msg.payload.instructions array.

Variable Substitution

Use {{varName}} placeholders in TwiML text, URLs, or raw TwiML. At runtime, these are replaced with values from msg.payload.twiVars. Supports dot notation: {{patient.name}}.
