n8n Slack Slash Command: Replay Jitterflow DLQ Webhooks

Replay Jitterflow DLQ Deliveries from Slack—Instantly

Use an n8n Slack slash command to check your Jitterflow dead-letter queue (DLQ), report how many deliveries failed (within Slack’s 3-second window), and then automatically replay each unresolved DLQ job through the Jitterflow API.

What this workflow does

• Receives a POST request from your configured Slack slash command via an n8n webhook.
• Lists unresolved DLQ entries by calling the Jitterflow API (up to 100 items).
• Responds to Slack immediately within the 3-second timeout, telling you how many failed deliveries will be replayed—or that none exist.
• Filters DLQ items to only replay entries that include a job ID.
• Replays deliveries for each remaining DLQ job using the Jitterflow API, continuing even if replay errors occur.

Use cases

• SaaS operations: Quickly recover from failed delivery attempts without digging through logs.
• Automation engineers: Provide a simple “retry DLQ” action via Slack for on-call and incident response.
• Workflow monitoring: Get an immediate Slack status count before the replay run starts.

Technical details

• Slack integration via a slash command → n8n webhook (POST request).
• Jitterflow API for:
  • Listing unresolved DLQ entries (up to 100)
  • Replaying DLQ jobs
• Nodes/steps: filter, webhook, sticky note, respond to webhook, and the verified community node n8n-nodes-jitterflow.

Setup

• Install n8n-nodes-jitterflow (Settings → Community Nodes on self-hosted n8n).
• Create a Jitterflow API credential in n8n and select it in both Jitterflow steps (DLQ list + replay).
• Activate the workflow, copy the production webhook URL, and configure your Slack app’s slash command to send POST requests to it.
