Zapier advanced error handling guide

When you run automated workflows in Zapier, app errors, timeouts, and connection issues can interrupt important tasks. By configuring advanced error handling settings, you can control how each Zap responds to problems, reduce noise from non-critical errors, and keep your automations running smoothly.

This guide explains the advanced settings available on the Zap editor, how they affect runs, and how to choose the best option for your use case.

Where to find advanced Zapier error settings

You configure error handling per Zap. These settings apply to the entire workflow rather than to a single step.

1. Open your Zap in the Zap editor.
2. In the left panel, locate the Advanced section (gear icon or similar, depending on the interface version).
3. Expand the advanced options to see how your Zap handles:

• App errors
• Connection issues
• Timeouts
• Throttle errors
• Authentication and permission errors

Changes you make here affect future Zap runs from the moment you turn the Zap back on.

Zapier behavior for common error types

Different problems can arise during a Zap run. Zapier uses a consistent set of rules so you can predict what will happen when something goes wrong.

How Zapier handles app errors

An app error happens when a connected app rejects a request. This usually appears as a 4xx or 5xx HTTP status code, or as a clear error message from the app’s API.

Typical causes include:

• Invalid or missing data in a field
• Trying to create a duplicate record that the app blocks
• Using a feature your plan in the app does not support
• Temporary server problems in the app

By default, if a step encounters an app error, the Zap run is marked as errored and stops at that step. In many cases you can see the details in the Zap run log and fix the data or configuration before re-running.

How Zapier handles connection issues

Connection issues occur when Zapier cannot reach an app or service over the network. These issues can be short-lived but can still interrupt runs.

Common connection issues include:

• DNS failures
• Temporary internet interruptions
• App API endpoints going offline
• SSL or TLS handshake errors

When a connection issue appears, Zapier typically retries a few times in the background. If the problem persists beyond the retry policy, the step fails and the whole run is marked as errored.

How Zapier handles timeouts

A timeout occurs when a step takes longer than the platform allows to receive a response from an app. Long-running processes, such as large data exports, can trigger timeouts.

When a timeout happens:

• The step is considered failed.
• The Zap run is marked as errored.
• You see a timeout message in the run log.

Some apps offer asynchronous operations or webhooks to avoid timeouts. In those cases, consider restructuring your Zap to rely on triggers or follow-up steps that fire when the app finishes processing.

How Zapier handles throttle and rate-limit errors

Many APIs limit the number of requests you can send in a given time window. When your Zap sends too many requests, the app may return a throttle or rate-limit error, often with an HTTP 429 status code.

In these cases, Zapier may:

• Pause briefly before retrying the request.
• Spread out subsequent requests.
• Mark the run as errored if the app keeps rejecting requests.

If you frequently see rate-limit errors, reduce the number of Zaps hitting that app, stagger schedules, or consolidate steps into fewer requests where possible.

How Zapier handles authentication errors

Authentication and permission problems arise when an account connection is invalid or does not have the rights required by the action.

Typical triggers include:

• Revoked access tokens
• Expired OAuth sessions
• Changed passwords or API keys
• Insufficient permissions for the connected user

When these occur, Zapier stops the Zap run and records an error. You usually need to:

1. Open the My apps section.
2. Reconnect or reauthorize the affected app.
3. Return to the Zap and re-run the affected items if needed.

Choosing Zapier settings for failed, halted, and successful runs

The advanced panel includes options that determine whether a Zap run should be considered failed, halted, or successful even when individual steps encounter problems.

Mark Zapier runs as failed on errors

Use this mode when you want maximum visibility into problems.

When enabled, Zapier treats any unhandled error in a step as a failed run:

• The run appears in your Zap history with an error status.
• Subsequent steps do not execute.
• You can investigate the details in the run log.

This is a good choice for business-critical workflows such as payment processing, contract creation, or compliance-related notifications where every failure needs follow-up.

Let Zapier halt runs for manual review

Some errors require human judgment instead of an automatic pass or fail. For these cases, you can configure the Zap to halt.

When a run halts:

• The Zap stops at the problematic step.
• The run is flagged for manual review.
• You can open the run, inspect the data, and decide whether to fix and replay it.

This option is useful for workflows involving content moderation, sensitive data review, or exceptions that occur only occasionally and are not predictable in advance.

Allow Zapier runs to succeed with handled issues

Not every problem should count as a failure. Some Zaps are designed to skip items that do not meet certain conditions or to continue even when a non-essential step has trouble.

In these cases, configure your Zapier settings so that:

• Expected, minor issues do not mark the whole run as failed.
• Downstream steps continue when earlier errors are clearly non-critical.
• The run status is marked as successful but may still record warnings or notes in the log.

Examples include:

• Skipping records that already exist in a CRM.
• Ignoring non-essential notification errors while still completing main database updates.
• Allowing optional steps, such as posting to a secondary channel, to fail silently.

Configuring Zapier error behavior step by step

Follow this process when you want to adjust error handling for a specific workflow.

1. Open the Zap and carefully review each trigger and action step.
2. Identify which steps are business-critical and which are optional.
3. In the advanced settings, choose whether a run should fail, halt, or succeed if a step encounters an error.
4. Save your configuration and turn the Zap on.
5. Trigger a test run using realistic data.
6. Check the Zap history to confirm that errors are treated as you expect.

Review these settings regularly, especially after adding new steps or connecting new apps.

Best practices for reliable Zapier workflows

To get consistent results from your automations, combine advanced error handling with thoughtful design choices.

• Validate inputs early: Where possible, use filters or Formatter steps to verify data before sending it to connected apps.
• Simplify complex Zaps: Break large workflows into smaller Zaps connected by webhooks or storage so errors are easier to isolate.
• Monitor history: Check your Zap run logs regularly to spot repeating issues, then adjust settings or mappings.
• Use test environments when available: If apps support sandbox accounts, configure and test new workflows there first.
• Keep connections updated: Periodically reauthorize app connections to prevent authentication surprises.
