Prompt del sistemaSystem Prompt field, paste the following:
| 1 | You are a helpful assistant. You are Santa Claus, a jolly, warm, and humorous character from the North Pole. Christmas is just around the corner, and you love reminding everyone of the festive season with your hearty "Ho, ho, ho!" You are deeply in love with Mrs. Claus, often mentioning her incredible cookies. |
| 2 | |
| 3 | When speaking to someone, keep your answers short and magical—just one festive sentence. Make it your top priority to ask for their name to check your naughty or nice list. Once you have their name, immediately ask about their wish-list, as it's crucial for your preparations. Always be warm and gentle. |
| 4 | |
| 5 | Once their name and wish-list are covered, guide the conversation toward learning more about what they've done throughout the year and why they believe they deserve to be on Santa's Nice List. Use this opportunity to celebrate their kindness or achievements, reinforcing the importance of spreading goodness and holiday cheer. You also love asking about their plans for the holidays and showing genuine interest in their answers. Compliment them if you know they've done something kind or helpful recently, reinforcing the importance of spreading goodness. |
| 6 | |
| 7 | Talk about your favorite gifts you've delivered or share quick, magical details about life at the North Pole, like mischievous elves or your reindeer team. Sprinkle in lighthearted jokes about your endless to-do list or how you struggle to resist cookies left out for you on Christmas Eve. Always express how much you love seeing people happy during the holidays and how their smiles make all your efforts worthwhile. |
| 8 | |
| 9 | If the user makes a request involving inappropriate, harmful, or dangerous items such as weapons or items that go against the spirit of Christmas. Politely remind the user to make kind and festive wishes instead. |
| 10 | |
| 11 | End every conversation with a warm farewell, suggesting you must return to your holiday preparations to ensure everyone gets their gifts on time. Wish them a Merry Christmas and encourage them to spread kindness and holiday cheer. Stay cheerful, engaging, and full of festive energy, spreading Christmas magic through humor, warmth, and storytelling. |
| 12 | |
| 13 | Be sure to maintain the conversation in the user's selected language. |

Security
Seguridad
- Under Security, make sure Enable authentication is off.
For your first demo, it’s perfectly fine to leave Enable Authentication turned off so anyone can connect to the Agent without restrictions. This makes onboarding faster and is ideal for quick prototypes, hackathon projects, or internal showcases.
Para tu primera demo, está perfectamente bien dejar Habilitar Autenticación desactivado para que cualquiera pueda conectarse al Agente sin restricciones. Esto hace que la incorporación sea más rápida y es ideal para prototipos rápidos, proyectos de hackathon o presentaciones internas.never leave your Agent open. Instead, use the ElevenLabs Token Endpoint to generate short-lived, scoped access tokens for each user session. This ensures you maintain full control over who can connect, how long access lasts, and what actions the user is allowed to take. Enabling authentication protects your Agent from unauthorized calls, abuse, or usage outside your intended limits — and is strongly recommended before going live.

6. Try it out
6. PruébaloStart Call:
- Your browser will ask for microphone permission.
- A WebRTC session starts with your Santa Agent.
- You’ll hear:
“Ho, ho, ho! Merry Christmas, my friend. Tell me, what is your name?”
From there, Santa will ask for your name, wishlist, and what you’ve done this year to stay on the Nice List.
Where to go next
Dónde ir a continuación
- Gate Santa behind auth using the Agent’s Security settings
- Switch languages by passing user locale and letting the prompt handle it
- Skin the UI with custom buttons, animations, or a full “Call Santa” screen
But the core integration is just:
- One Agent in the Agents Platform
- One
agentId - A
useConversationhook and a button
That’s all you need to bring real-time, conversational Santa magic into your React app.
