Connect Retellai to Slack
Automate Retellai and Slack with AI
Retell AI handles inbound voice while your team coordinates in Slack. Your Operator agent on OpenClaw posts Retell call summaries and escalations to the Slack channel you name, opens threads when a caller needs a human follow up, and logs Slack decisions back against the Retell call record when your workflow requires it. Ask which Retell queues still have open Slack mentions and it lists both in one view.
It reaches both apps directly or through connectors like Composio MCP and Pipedream MCP, which handle the sign in and token refresh, so there is no Zap to build and no API keys to paste.

How it works
Tell the agent what you want to happen between Retellai and Slack, for example to watch one and act in the other, or to keep the two in step. It reads what it needs from Retellai, works out what to do, and runs the matching action in Slack without you mapping a single field.
You can have it run once, on a schedule, or whenever something changes. Ask it for a status any time and it reads the latest from both apps back to you in the same chat.
Common questions about Retellai and Slack
- How do I connect Retellai and Slack to Operator?
- You authorize Retellai and Slack once each from your Operator dashboard. Operator holds both connections and refreshes the access tokens for you, so your agent keeps working across them without you signing in again.
- What can my agent do across Retellai and Slack?
- You describe the outcome in plain language and your agent works between the two, reading from one and acting in the other. It picks the right Retellai and Slack actions on its own, so you do not map fields or pick triggers.
- Can my agent keep Retellai and Slack in sync?
- Yes. It can watch Retellai and act in Slack, or keep both in step, reading from one and running the matching update in the other. This runs on demand when you ask or on a schedule you set.
- Do I need to build a workflow or write code?
- No. There is no workflow to build, no fields to map, and no API keys to paste. Operator manages both connections, and you give the agent instructions in plain language.
