Hello, I’m currently using conversation nodes to extract variables and pass them into an API Request node. However, instead of receiving the actual values, the API request is receiving the variable placeholders as literal strings (e.g., {{CustomerName}}). This setup used to work correctly, so I’m unsure what has changed. Could you please help me identify what might be causing this issue? Thank you!

Ensure you pass the actual variable values using assistantOverrides.variableValues when starting the call, and confirm the placeholder names like , {{CustomerName}}) exactly match the keys, including case sensitivity. Use only supported nodes like assistant messages or API Request nodes for variable substitution..

Can you give some more detail on how I use assistantOverrides.variableValues with my placeholder {{CustomerName}} please?

Define it in your assistant’s message and pass its value via assistantOverrides.variableValues like, { "CustomerName": "Alice" } when starting the call, ensuring exact name match and correct JSON structure for proper substitution..
