Escalate an unanswered interested reply in Slack when its reminder falls due

If a reminder on an Interested lead comes due and the prospect still has the last word, Master Inbox posts an escalation to Slack so a manager can step in before the lead goes cold.

  5. Add a condition: Last message is from the prospect.

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": "Escalate an unanswered interested reply in Slack when its reminder falls due",
  "trigger_type": "due_reminder",
  "trigger_config": {},
  "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: "Escalate an unanswered interested reply in Slack when its reminder falls due". 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

How do I set the reminder in the first place?

Pair it with a workflow on the Interested label that sets a reminder, for example 8, 24 or 48 hours later.

What if the rep already answered?

The last message condition fails, so no escalation is posted.

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.
