Post every reply the AI agent sends to Slack for QA

Each message sent by a reply agent is posted to a QA channel in Slack with the prospect and thread link, so managers can spot-check AI replies as they go out.

Why teams run it

Trust in autopilot grows when the team can see what it sends.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Post every reply the AI agent sends to Slack for QA.
Set the trigger to Sending Message and choose All channels.
Add a condition: Sent from is the reply agent.
Add the action Notify in Slack: Post the sent reply, prospect and thread link to #ai-qa.
Save the workflow and switch it to Active.

Before you start, connect Slack under Settings, Integrations.

Or create it with the API

Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields. This workflow also uses conditions: add them under trigger_config.conditions, as shown on the conditions page.

curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
  -H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "name": "Post every reply the AI agent sends to Slack for QA",
  "trigger_type": "send_message",
  "trigger_config": {
    "channel_ids": [
      "-1"
    ]
  },
  "action_configs": [
    {
      "action_type": "slack_notify",
      "payload_variables": [
        "name",
        "company_name",
        "label_names",
        "text",
        "thread_url"
      ],
      "show_draft": true
    }
  ]
}'

Or ask Claude, ChatGPT or Grok to build it

Our workflow guide is written for AI agents to read. Give your assistant your API key and this prompt:

Read https://app.masterinbox.com/public-workflow-api.md and use my Master Inbox API key to create this workflow: "Post every reply the AI agent sends to Slack for QA". First call GET /workflows/filter-fields and look up my label, list and channel ids, then create the workflow and tell me what you set up.

Questions

Can I log manual replies separately?

Yes. Set the sent from condition to manual for a second channel.

Can I log to a sheet instead?

Yes. Use a webhook action to Google Sheets through Zapier, Make or n8n.

Can I build this workflow through the API?

Yes. Send the create-workflow request shown on this page with your Master Inbox API key. The API checks the payload first and lists every problem by field if anything is off.

Which plan includes this?

This workflow works on the Team plan. Every plan has unlimited users and starts with a free 7-day POC.
