Dynamically generate a webpage from user request using OpenAI structured output
This workflow is a experiment to build HTML pages from a user input using the new Structured Output from OpenAI. How it works: Users add what they want to build as a query parameter The OpenAI node generate an interface following a structured output defined in the body The JSON output is then converted to HTML along with a title The HTML is encapsulated in an HTML node (where the Tailwind css script is added) The HTML is rendered to the user via the Webhook response. Set up steps Create an OpenAI API Key Create the OpenAI credentials Use the credentials for both nodes HTTP Request (as Predefined Credential type) and OpenAI Activate your workflow Once active, go to the production URL and add what you'd like to build as the parameter "query" Example: https://production_url.com?query=a%20signup%20form Example of generated page
By Agent StudioAI agent with charts capabilities using OpenAI structured output and Quickchart
This workflow is an experiment to integrate charts in AI Agents, using the new Structured Output from OpenAI and Quickchart.io. How it works Users chat with an AI Agent. Anytime the AI Agent considers a chart is needed, it calls a tool to generate a chart OpenAI generates a chart using the Quickchart definition This object is added at the end of a Quickchart.io URL (see documentation) The url is added in the conversation via the AI Agent as markdown. Set up steps Create an OpenAI API Key Create the OpenAI credentials Use the credentials for the HTTP Request node (as Predefined Credential type) Activate your workflow Start chatting For example, you can ask the AI Agent to generate a chart about the top 5 movies at the box office Start exploring the limits Shout-out Quickchart.io is an amazing open source project that provides a free API to test. Go check them out! Example of chart
By Agent StudioExtract and process information directly from PDF using Claude and Gemini
Overview This workflow helps you compare Claude 3.5 Sonnet and Gemini 2.0 Flash when extracting data from a PDF This workflow extracts and processes the data within a PDF in one single step, instead of calling an OCR and then an LLM” How it works The initial 2 steps download the PDF and convert it to base64. This base64 string is then sent to both Claude 3.5 Sonnet and Gemini 2.0 Flash to extract information. This workflow is made to let you compare results, latency, and cost (in their dedicated dashboard). How to use it Set up your Google Drive if not already done Select a document on your Google Drive Modify the prompt in "Define Prompt" to extract the information you need and transform it as wanted. Get a Claude API key and/or Gemini API key Note that you can deactivate one of the 2 API calls if you don't want to try both Test the Workflow
By Agent StudioConnect Retell Voice Agents to custom functions
Overview This workflow allows you to trigger custom logic in n8n directly from Retell's Voice Agent using Custom Functions. It captures a POST webhook from Retell every time a Voice Agent reaches a Custom Function node. You can plug in any logic—call an external API, book a meeting, update a CRM, or even return a dynamic response back to the agent. Who is it for For builders using Retell who want to extend Voice Agent functionality with real-time custom workflows or AI-generated responses. Prerequisites Have a Retell AI Account A Retell agent with a Custom Function node in its conversation flow (see template below) Set your n8n webhook URL in the Custom Function configuration (see "How to use it" below) (Optional) Familiarity with Retell's Custom Function docs Start a conversation with the agent (text or voice) Retell Agent Example To get you started, we've prepared a Retell Agent ready to be imported, that includes the call to this template. Import the agent to your Retell workspace (top-right button on your agent's page) You will need to modify the function URL in order to call your own instance. This template is a simple hotel agent that calls the custom function to confirm a booking, passing basic formatted data. How it works Retell sends a webhook to n8n whenever a Custom Function is triggered during a call (or test chat). The webhook includes: Full call context (transcript, call ID, etc.) Parameters defined in the Retell function node You can process this data and return a response string back to the Voice Agent in real-time. How to use it Copy the webhook URL (e.g. https://your-instance.app.n8n.cloud/webhook/hotel-retell-template) Modify the Retell Custom Function webhook URL (see template description for screenshots) Edit the function Modify the URL Modify the logic in the Set node or replace it with your own custom flow Deploy and test: Retell will hit your n8n workflow during the conversation Extension Ideas Call a third-party API to fetch data (e.g. hotel availability, CRM records) Use an LLM node to generate dynamic responses Trigger a parallel automation (Slack message, calendar invite, etc.) 👉 Reach out to us if you're interested in analyzing your Retell Agent conversations.
By Agent StudioStore retell transcripts in Sheets, Airtable or 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_analyzed webhook 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: Airtable Google Sheets Notion How it works Receives a webhook POST request from Retell when a call has been analyzed. Filters out any event that is not callanalyzed (Retell sends webhooks for callstarted, callended and callanalyzed) 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://your-instance.app.n8n.cloud/webhook/poc-retell-analysis) 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.callanalysis.customanalysis_data object. Additional Notes Phone numbers are extracted depending on the call direction (fromnumber or tonumber). 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. 👉 Reach out to us if you're interested in analysing your Retell Agent conversations.
By Agent StudioPopulate Retell dynamic variables with Google Sheets data for call handling
Overview This workflow provides Retell agent builders with a simple way to populate dynamic variables using n8n. The workflow fetches user information from a Google Sheet based on the phone number and sends it back to Retell. It is based on Retell's Inbound Webhook Call. Retell is a service that lets you create Voice Agents that handle voice calls simply, based on a prompt or using a conversational flow builder. Who is it for For builders of Retell's Voice Agents who want to make their agents more personalized. Prerequisites Have a Retell AI Account Create a Retell agent Purchase a phone number and associate it with your agent Create a Google Sheets - for example, make a copy of this one. Your Google Sheet must have at least one column with the phone number. The remaining columns will be used to populate your Retell agent’s dynamic variables. All fields are returned as strings to Retell (variables are replaced as text) How it works The webhook call is received from Retell. We filter the call using their whitelisted IP address. It extracts data from the webhook call and uses it to retrieve the user from Google Sheets. It formats the data in the response to match Retell's expected format. Retell uses this data to replace dynamic variables in the prompts. How to use it See the description for screenshots! Set the webhook name (keep it as POST). Copy the Webhook URL (e.g., https://your-instance.app.n8n.cloud/webhook/retell-dynamic-variables) and paste it into Retell's interface. Navigate to "Phone Numbers", click on the phone number, and enable "Add an inbound webhook". In your prompt (e.g., "welcome message"), use the variable with this syntax: {{variable_name}} (see Retell's documentation). These variables will be dynamically replaced by the data in your Google Sheet. Notes In Google Sheets, the phone number must start with '+. Phone numbers must be formatted like the example: with the +, extension, and no spaces. You can use any database—just replace Google Sheets with your own, making sure to keep the phone number formatting consistent. 👉 Reach out to us if you're interested in analysing your Retell Agent conversations.
By Agent StudioTrack OpenAI Admin API usage and costs automatically with Google Sheets
Overview This workflow aims to help you and your team track your expenses with OpenAI It automatically collects your OpenAI organization’s API usage and cost data every few days and saves it to a ready-to-use Google Sheets template. It pulls detailed metrics for every project and API key, including token usage, model breakdowns, and costs per line item, making it easy for your team to analyze and track spend over time! Who is it for Finance or ops teams tracking AI usage and spend Data/analytics teams needing detailed project-level breakdowns Technical leads or admins managing OpenAI organization usage and cost Anyone needing a simple audit trail or historical record of OpenAI API activity How to get started Access to your organization’s OpenAI Admin API key -> Note: it's a different API than the one you use to call the models. Add your credentials in all OpenAI Admin nodes as Predefined Credentials > OpenAI. Create your Google Sheets credentials Get the Google Sheets template (copy to your Drive) How it works Trigger: The workflow runs automatically on a schedule (every 3 days by default, but you can adjust). Fetch Data: Calls OpenAI’s Admin API to get all token usage and cost details for the reporting window. Enrich Data: Resolves project names and API key names for clarity in reports. Write to Sheets: Appends new usage and cost data to your Google Sheet, with one row per project/key/period. Google Sheets Template Use our template to track OpenAI's cost and usage Notes All data is appended, so your sheet keeps historical records. But ⚠️ if you run the workflow manually or change the schedule, you could end up with duplicated rows API key and project enrichment makes reports easier to read. You can adapt the workflow to save results anywhere: BigQuery, Airtable, DB, or even another spreadsheet. Easy to change schedule or reporting window to fit your team’s needs. Extra Depending on your internal processes, you could also generate monthly files and automatically send the report to your finance team via email or Slack, for example. The possibilities are endless! Note that we intended to do the same with Anthropic and Gemini via API and n8n built-in methods. At this stage, it is not possible to do it, but it could probably be done using Browser Agents! Service If you need help implementing the template or modifying it, just reach out 💌
