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.
| Node | Category | Type | Operation |
|---|---|---|---|
| Webhook | Trigger | Webhook | See node parameters |
| Set fields to export | Transform | Edit Fields | See node parameters |
| Save to Airtable | Data store | Airtable | create |
| Save to Excel | Data store | Google Sheets | append |
| Save to Notion | Integration | Notion | databasePage |
| Filter - only call ended | Routing | Filter | See node parameters |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- 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.

Automatically store Retell transcripts in Google Sheets/Airtable/Notion from webhook
Automatically store Retell transcripts in Google Sheets/Airtable/Notion from webhook
Overview
- This workflow stores the results of a Retell voice call (transcript, analysis, etc.) once it has ended and been analyzed.
- It listens for
call_analyzedwebhook events from Retell and stores the data in Airtable, Google Sheets, and Notion (choose based on your stack). - Useful for anyone building Retell agents who want to keep a detailed history of analyzed calls in structured tools.
Who is it for
For builders of Retell's Voice Agents who want to store call history and essential analytic data.
Prerequisites
- Have a Retell AI Account
- Create a Retell agent
- Associate a phone number with your Retell agent
- Set up one of the following:
- An Airtable base and table (example: "Transcripts")
- A Google Sheet with a “Transcripts” tab
- A Notion database with columns to match the transcript fields
- Templates:
How it works
- Receives a webhook POST request from Retell when a call has been analyzed.
- Filters out any event that is not
call_analyzed(Retell sends webhooks forcall_started,call_endedandcall_analyzed) - Extracts useful fields like:
- Call ID, start/end time, duration, total cost
- Transcript, summary, sentiment
- Stores this data in your preferred tool:
- Airtable
- Google Sheets
- Notion
How to use it
- Copy the webhook URL (e.g., `https://example.invalid/REPLACE_WITH_N8N_ENDPOINT and paste it in your Retell agent under "Webhook settings" then "Agent Level Webhook URL".
- Make sure your Airtable, Google Sheet, or Notion databases are correctly configured to receive the fields.
- After each call, once Retell finishes the analysis, this workflow will automatically log the results.
Extension
- If you use any "Post-Call Analysis" fields, you can add columns to your Airtable, Google Sheet, or Notion database.
- Then fetch the data from the
call.call_analysis.custom_analysis_dataobject.
Additional Notes
- Phone numbers are extracted depending on the call direction (
from_numberorto_number). - Cost is converted from cents to dollars before saving.
- Dates are converted from timestamps to local ISO strings.
- You can remove any of the outputs (Airtable, Google Sheets, Notion) if you're only using one.

Sticky Note
POST Webhook receiving your Retell events
Sticky Note2
Only keep the call_analyzed events (it contains all data points)
Sticky Note3
Prepare your data to be sent to your preferred database. If you add more data or post call analytics, you will add fields here.
Sticky Note4
Save all fields from Retell to Airtable
Sticky Note5
Save all fields from Retell to Google Sheets
