Lindy Incident Runbook

Lindy Incident Runbook

Overview

Incident response procedures for Lindy AI agent failures. Covers platform outages, individual agent failures, integration breakdowns, credit exhaustion, and webhook endpoint failures.

Prerequisites

• Access to the affected Lindy workspace and task history
• Ownership and escalation contacts for each affected integration
• Read access to the receiving application's health checks and sanitized logs
• A queue, manual route, or other documented fallback for critical events
• An approved location for incident receipts that excludes secrets and payloads

Instructions

1. Declare severity from customer impact and record the UTC detection time.
2. Bound the failure to the platform, one agent, an integration, credits, or the receiving endpoint before changing configuration.
3. Preserve sanitized task IDs and error evidence, then activate the smallest safe fallback that stops additional loss or duplicate actions.
4. Apply the matching playbook below and verify recovery with fresh synthetic work rather than by retrying customer data blindly.
5. Monitor the recovery window, document the outcome, and assign prevention work before resolving the incident.

Incident Severity Levels

Quick Diagnostics (First 5 Minutes)

Step 1: Check Lindy Platform Status

# Is Lindy up?
curl -s -o /dev/null -w "Lindy API: HTTP %{http_code}\n" \
  "https://public.lindy.ai" --max-time 5

# Check status page
echo "Status page: https://status.lindy.ai"

Step 2: Check Your Integration

# Is your webhook receiver up?
curl -s -o /dev/null -w "Our endpoint: HTTP %{http_code}\n" \
  "https://api.yourapp.com/health" --max-time 5

# Is the webhook auth working?
curl -s -o /dev/null -w "Webhook auth: HTTP %{http_code}\n" \
  -X POST "https://api.yourapp.com/lindy/callback" \
  -H "Authorization: Bearer $LINDY_WEBHOOK_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"test": true}' --max-time 5

Step 3: Check Credit Balance

Log in at > Settings > Billing

• Credits at 0? Agents stop processing
• Credits low? Non-essential agents may be paused

Incident Playbooks

Incident: Lindy Platform Outage (SEV1)

Symptoms: All agents failing, status.lindy.ai shows incident Impact: All Lindy-dependent workflows halted

Runbook:

1. Confirm outage at https://status.lindy.ai
2. Notify team: "Lindy platform outage confirmed. All agents affected."
3. Activate fallback procedures:
   • Route support emails to human inbox
   • Disable webhook triggers from your app
   • Queue events for replay when Lindy recovers
4. Monitor status page for recovery
5. When recovered: re-enable triggers, replay queued events, verify agent health

Fallback code:

async function triggerLindyWithFallback(payload: any) {
  try {
    const response = await fetch(WEBHOOK_URL, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${SECRET}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(payload),
      signal: AbortSignal.timeout(10000), // 10s timeout
    });

    if (!response.ok) throw new Error(`HTTP ${response.status}`);
    return { routed: 'lindy' };
  } catch (error) {
    console.error('Lindy unreachable, activating fallback:', error);
    await queueForReplay(payload); // Store for later
    await notifyTeam(`Lindy trigger failed: ${error}`);
    return { routed: 'fallback' };
  }
}

Incident: Individual Agent Failure (SEV2)

Symptoms: Specific agent tasks showing "Failed" status Impact: One workflow affected, others may be fine

Runbook:

1. Open agent > Tasks tab > Filter by "Failed"
2. Click latest failed task — identify the failing step
3. Diagnose based on failing step type:
   • Trigger step: Auth expired? Filter too restrictive?
   • Action step: Integration token expired? Target API down?
   • Condition step: Ambiguous condition prompt?
   • Agent step: Looping? Exit conditions unreachable?
4. Fix the root cause:
   • Re-authorize expired integrations
   • Fix action configuration
   • Simplify condition prompts
   • Add fallback exit conditions
5. Test with a manual trigger
6. Monitor next 5 tasks for success

Incident: Integration Auth Expired (SEV2-3)

Symptoms: Actions failing with "Not authorized" or "Token expired" Impact: All tasks using that integration fail

Runbook:

1. Identify which integration is failing (Gmail, Slack, Sheets, etc.)
2. In Lindy dashboard: Settings > Integrations
3. Find the expired connection (may show warning icon)
4. Click Re-authorize and complete OAuth flow
5. Re-test the agent with a manual trigger
6. Set calendar reminder for 90-day re-authorization check

Incident: Credit Exhaustion (SEV2-3)

Symptoms: Agents stop running, no new tasks created Impact: All agents paused until credits refill

Runbook:

1. Confirm at Settings > Billing: credits at 0
2. Immediate: Upgrade plan or purchase additional credits
3. Investigate: Which agent consumed the most credits?
4. Root cause: trigger storm? looping agent step? large model overuse?
5. Fix: Add trigger filters, set exit conditions, downgrade model
6. Prevent: Set budget alerts at 50%, 80%, 95% thresholds

Incident: Webhook Endpoint Failure (SEV2-3)

Symptoms: Lindy agent runs but your callback never receives data Impact: Agent completes but results are lost

Runbook:

1. Check your endpoint health: curl -s https://api.yourapp.com/health
2. Check server logs for incoming requests from Lindy
3. Verify the HTTP Request action URL matches your production endpoint
4. Test endpoint independently: send a POST with curl
5. If endpoint was down: replay failed tasks (re-trigger the agent)
6. If URL mismatch: update URL in Lindy agent HTTP Request action

## Incident Report

**Date**: YYYY-MM-DD
**Severity**: SEV[1-4]
**Duration**: [start time] to [end time] ([total minutes])
**Impact**: [what was affected, customer impact]

### Timeline
- HH:MM — Issue detected via [monitoring/user report]
- HH:MM — On-call paged, diagnostics started
- HH:MM — Root cause identified: [cause]
- HH:MM — Fix applied: [what was done]
- HH:MM — Service restored, monitoring confirmed

### Root Cause
[Technical description of what failed and why]

### Resolution
[What was done to fix it]

### Prevention
- [ ] [Action item 1]
- [ ] [Action item 2]
- [ ] [Action item 3]

Output

Produce an incident receipt that records the severity, UTC start and recovery times, affected agents and integrations, sanitized task IDs, the confirmed failure boundary, mitigation, recovery checks, and follow-up owners. Keep credentials, webhook secrets, customer payloads, and complete private endpoint URLs out of the receipt.

Examples

For an expired integration, record the failing action and task ID, preserve the original error text without its token, re-authorize the connection, and verify five subsequent tasks before resolving the incident. For a platform outage, record the status-page confirmation, queue or fallback activation time, replay count after recovery, and the check that proved normal processing resumed.
