Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.

Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.

How it works

The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.

Setup

  1. Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
  2. Connect your own credentials through n8n’s credential store. Replace REPLACE_WITH_* values with your resource identifiers.
  3. Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
  4. Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.

Requirements

An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.

Credential types declared in the source

  • googleCalendarOAuth2Api
  • googleDriveOAuth2Api
  • httpHeaderAuth
  • openAiApi
  • qdrantApi

Workflow notes

STEP 6 - VOICEFLOW

STEP 6 - VOICEFLOW

  • Register on Voiceflow
  • Create the workflow as shown in the following image
  • There are 3 "Captures": -- n8n_order -- n8n_appointment -- n8n_rag
  • Add in the created functions the url of the corresponding n8n Webhook trigger node
  • Test your Agent
  • Get your projectID
  • In the Widget section choose Chat or Voice and copy the installation script

PS. You can import a Twilio number to assign it to your agent for becoming a Phone Agent

Build a Chatbot, Voice Agent and Phone Agent with Voiceflow, Google Calendar and RAG

Purpose and structure

This folder contains the Build a Chatbot, Voice Agent and Phone Agent with Voiceflow, Google Calendar and RAG workflow. Its executable nodes use agent, chainLlm, documentDefaultDataLoader, embeddingsOpenAi, googleCalendar, googleDrive, httpRequest, lmChatOpenAi, manualTrigger, outputParserStructured, respondToWebhook, set, textSplitterTokenSplitter, toolVectorStore, vectorStoreQdrant, webhook. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.

Setup

Import inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.

Entry points
