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

  • googlePalmApi
  • httpCustomAuth
  • openAiApi

Workflow notes

Prerequisites:
  • For the Text-to-Speech part, we'll use ElevenLabs.io, which is free and offers a variety of voices to choose from. However, you can also use the OpenAI "Generate audio" node instead.

  • Since there is no pre-built node for "ElevenLabs" in n8n, we'll connect to it through its API using the "HTTP Request" node.

Prerequisites:

  • "ElevenLabs API Key" (you can obtain it from their website).

  • "Voice ID" (you can also get it from ElevenLabs' "Voice Library").

Setup

  • In the URL parameter, replace "{{voice id}}" at the end of the URL with the Voice ID you obtained from ElevenLabs.io.

  • To set up your API Key, add custom authentication and include the following JSON with your acual ElevenLabs API Key:

{
 "headers": {
 "xi-api-key": "put-your-API-Key-here"
 }
}
