10/20/2025, 11:26 AMassistantId in your API call. For example:
javascript
const response = await vapi.calls.create({
workflow: { id: "your-workflow-id" },
assistantId: "your-assistant-id", // Make sure this is set
to: "+1234567890"
});
Double-check your assistant ID and try again—this should resolve the "Assistant ID not allowed" error.
