Video Introduction Want to automate your inbox or need a custom workflow? 📞 Book a Call | 💬 DM me on Linkedin Workflow Overview This workflow creates a recipe finder web application that connects to the API Ninjas Recipe API using n8n's HTTP Request node. Users submit search queries through a public web form, which triggers an API call to fetch matching recipes. The results—including recipe title, ingredients, and cooking instructions—are displayed in a formatted completion page. Why This Workflow Is Valuable This template demonstrates API-to-API integration, a crucial skill for connecting services that don't have pre-built n8n nodes. By using direct API calls, you gain access to the full functionality of external services. This pattern can be adapted to integrate virtually any tool with an API into your n8n workflows. Common Use Cases Create public-facing forms that query external databases Build custom search tools for specialized APIs Integrate niche services without dedicated n8n nodes Learn header authentication for secure API connections Setup & Configuration Register for API Ninjas: Sign up at API Ninjas to access their Recipe API Get your API Key: Locate your API key in the API Ninjas dashboard Configure Credentials: In n8n, create a new Header Auth credential Set the header name to match the API requirement (e.g., 'X-Api-Key') Paste your API key as the value Apply this credential to the HTTP Request node The Form Trigger generates a public URL for users to submit queries. Customize the form title, field labels, and completion message HTML to match your needs.

This workflow transforms n8n into a call automation system, where AI agents can talk directly with people over the phone using Twilio. This workflow integrates Ultravox AI voice agents with Twilio’s telephony service to fully automate outbound phone calls. Ultravox generates the AI conversation and audio, while Twilio handles the PSTN connection to the actual phone network, with the two services connected in real-time via a media stream. Key Advantages AI-Powered Conversations** – Leverage Ultravox agents to handle natural, real-time dialogues with customers. Seamless Telephony Integration** – Twilio ensures reliable phone call delivery worldwide. Flexible Setup** – You can easily change the target phone number, agent, or Twilio line directly in the workflow. Scalable Outreach** – Automates outbound calls for customer support, sales, or appointment reminders. Step-by-Step Guidance** – The workflow includes clear instructions for: Buying and configuring a Twilio number Creating an Ultravox agent Executing the final call How it Works Manual Trigger: The workflow is started manually by a user within n8n. Set Parameters: The "Set Params" node defines the crucial variables for the call: the Ultravox agent_id, the Twilio phone number to call from (twilio_number), and the destination phone_number to call. Initiate Ultravox Session: The "Create Ultravox Call" node sends an HTTP POST request to the Ultravox API. It specifies the agent to use and, crucially, informs Ultravox that the call will be handled by Twilio (medium: { twilio: {} }). Ultravox responds with a unique joinUrl (a WebSocket stream URL). Place the Twilio Call: The "Twilio Call" node uses the details from the previous steps. It instructs Twilio to make a call from the specified twilio_number to the target phone_number. The key instruction (twiml) tells Twilio to connect the call to the joinUrl provided by Ultravox, effectively streaming the audio between the participant and the AI agent. Set Up Steps Twilio Configuration: Log into your Twilio Console. Buy a phone number under the "Phone Numbers" section. Obtain your "Account SID" and "Auth Token" from the dashboard. In the "Twilio Call" node credentials, add your Twilio Account SID and Auth Token. In the "Set Params" node, set the twilio_number value to your newly purchased Twilio number (e.g., +1xxxxxxx). Ultravox Configuration: Log into your Ultravox App. Create a new AI Agent by configuring its voice, tools, and system prompt. Copy the ID of your newly created agent. In the "Set Params" node, set the agent_id value to your Ultravox agent's ID. Execute the Call: In the "Set Params" node, set the phone_number value to the destination number you wish to call (e.g., +1xxxxxxxx). Execute the workflow manually from the n8n editor. The AI agent will call the specified number through Twilio. Need help customizing? Contact me for consulting and support or add me on Linkedin.
