elevenlabs-twilio-memory-bridge

Personalization webhook service for ElevenLabs + Twilio voice agents with persistent caller memory.

What It Does

When a call arrives on your Twilio number, ElevenLabs' native integration triggers this webhook. The bridge looks up the caller's history, loads long-term memory facts and daily context notes, combines them with a customizable soul/personality template, and returns everything as a system prompt override so your agent greets each caller with full context.

Architecture

No audio proxying - ElevenLabs and Twilio handle media directly
Webhook only - called once per inbound call to inject context
File-based persistence - JSON files in ./data/, zero external dependencies
OpenClaw compatible - works with any OpenAI-compatible LLM endpoint

Endpoints

Endpoint	Method	Purpose
`/webhook/personalize`	POST	ElevenLabs calls this on inbound call
`/webhook/post-call`	POST	Optional post-call cleanup
`/api/memory/{phone_hash}`	POST	Add long-term fact about a caller
`/api/notes`	POST	Add global or caller-scoped context note
`/health`	GET	Health check

Setup

Clone repo, pip install -r requirements.txt
Copy .env.example to .env, fill in secrets
