Have you ever watched your Zapier dashboard fill up with endless “pending” tasks, eating through your monthly allowance before you could blink? You’re not alone. How to Fix Zapier Infinite Pending Loops is a critical skill for anyone scaling automations, especially in busy setups like Eternal Auto Blogger or n8n workflows. These loops happen when Zaps trigger themselves repeatedly from the same data, creating infinite cycles that leave executions stuck in pending limbo[1][2].
In my years automating content for SaaS clients across the UK, US, and Canada, I’ve battled these loops firsthand. They cost time, money—often £50-£200 in wasted tasks—and momentum. But with the right steps, you can diagnose, stop, and prevent them permanently. This comprehensive guide walks you through how to fix Zapier infinite pending loops, drawing from Zapier’s official help centre and community fixes[2]. Let’s dive in and get your automations running smoothly again.
Understanding How to Fix Zapier Infinite Pending Loops
Infinite pending loops in Zapier occur when a Zap’s output triggers its own trigger again, creating a self-perpetuating cycle. Unlike intentional Looping by Zapier apps, these are errors from misconfigured triggers like new rows in Airtable or HubSpot updates[1][2][5]. Tasks pile up as “pending,” often due to API timeouts or duplicate data detection failures.
Why does this hit hard? Free plans cap at 100 tasks monthly; paid ones from £15/month scale up but loops can burn £100+ quickly. In the UK, US, and Canada, where automation powers e-commerce and content sites, unresolved loops mean lost revenue. Understanding this is step one in how to fix Zapier infinite pending loops[2].
Key signs include Zap History showing repeated runs from identical data, status as “pending,” or “held” waiting for approval. Check your dashboard filters for “Pending” or “Held” to spot them early[4].
Fix Zapier Infinite Pending Loops – Immediate Steps to Stop Zapier Infinite Pending Loops
The fastest way to halt a loop? Turn off the Zap. Navigate to your Zaps list, find the looping one via Task History, and toggle it off. This stops consumption immediately, saving your quota[1].
Next, review Zap History: Click “Zap History” in the sidebar, filter by status (Pending/Held), and inspect data in/out for each step. Look for repeating triggers—like the same Airtable record ID[5]. Note the exact step causing the cycle for targeted fixes in how to fix Zapier infinite pending loops.
- Log into Zapier.
- Go to Zap History.
- Filter: “Pending” or “Looping.”
- Click a task > View data flow.
- Identify the repeating trigger data.
- Turn off the Zap.
This buys time without data loss. For multi-Zap loops (e.g., Pipedrive-Airtable syncs), disable all involved[9].
Diagnosing the Root Cause of Infinite Pending Loops
Loops stem from trigger-output feedback. Example: Zap A creates a Google Sheet row; Zap B (or same Zap) triggers on new rows, updating the sheet and re-triggering endlessly[2]. Pending status arises from rate limits or delays in apps like HubSpot line items[3].
Use Zapier’s history logs: Export data as CSV for analysis. Search for duplicate IDs or timestamps. Tools like Airtable’s “Find Many Records” often bundle data, causing “pending” in loops[5].
Pro tip: Test in isolation. Clone the Zap, disable actions post-trigger, and run. If it loops, the issue is upstream—fix the trigger app first when learning how to fix Zapier infinite pending loops.
Common Triggers Causing Loops
- Sheet/DB updates (Google Sheets, Airtable).
- CRM updates (HubSpot, Pipedrive).
- Cron jobs or schedules without deduping.
Add Filters to Prevent Zapier Infinite Pending Loops
Filters are your first defence. Insert a Filter by Zapier after the trigger: Set “Does Not Contain” on a field you’ll mark uniquely[2].
Step-by-step:
- Add Filter by Zapier post-trigger.
- Field: e.g., “Description” or “Notes.”
- Condition: Does Not Contain.
- Value: Unique marker like “#processed.”
- Test & turn on.
For two-Zap loops: Zap 1 adds “#ggl” to output; Zap 2 filters “Does Not Contain #ggl.” Swap markers per Zap[2]. This prevents 90% of cycles in how to fix Zapier infinite pending loops.

Using Unique Values in How to Fix Zapier Loops
Pair filters with unique values. In action steps, append a marker to a non-essential field, e.g., “Notes: Updated #cs {{timestamp}}.”[2]
For single-Zap loops:
- In action: Add to Description: “#cs – processed on {{zap_meta_human_now}}.”
- Filter pre-action: Description Does Not Contain “#cs.”
Timestamps ensure uniqueness. For Airtable, use Record ID + timestamp[5]. This breaks the feedback perfectly in how to fix Zapier infinite pending loops.
Advanced: Use Formatter by Zapier for dynamic IDs, avoiding static text.
Advanced Techniques for Zapier Pending Loop Fixes
Delays slow loops, giving spotting time: Add Delay by Zapier (1-5 mins) post-trigger[1]. Not preventive, but buys quota.
For looping apps: In “Looping by Zapier,” ensure proper iteration. Airtable issues? Use “Create Loop from Line Items” with single-record mapping[5]. HubSpot line items need counters and post-loop filters[3].
Plan workflows: Map triggers/actions on paper first. Avoid two-way syncs—Zapier doesn’t support them natively[2]. Integrate with Eternal Auto Blogger by filtering cron outputs.
API Timeouts and Cron Fixes
Pending from timeouts? Increase delays or use Webhooks. For cron jobs, add unique run IDs[related context].
Common Pitfalls and How to Avoid Them
Pitfall 1: Overlooking multi-app loops. Solution: Audit all Zaps touching the app[9].
Pitfall 2: Filters too early/late. Place post-trigger, pre-looping action.
Pitfall 3: Ignoring task history. Always check before resets (monthly on 01/MM/YYYY).
Pitfall 4: Looping apps misconfig. Use “Preview Loop Values” correctly[5]. These snag beginners but vanish with how to fix Zapier infinite pending loops practice.
8 Expert Tips for Loop-Free Automation
1. Plan visually: Sketch Zaps to spot cycles.
2. Test small: Run with 1-2 records.
3. Use paths: Branch logic avoids loops.
4. Monitor quotas: Set alerts for 80% usage.
5. Unique everywhere: Timestamp all outputs.
6. Community check: Search Zapier Community first[7].
7. Upgrade wisely: Starter (£15/mo) adds filters.
8. Backup Zaps: Clone before edits.
