Replay failed tasks in Zaps

tutorial
Last updated:

Your task history show all the tasks your Zaps have tried to run. Each task in your task history will have one of five task statuses. Failed or unsuccessful tasks can be manually or automatically replayed.

Note

Replaying a Zap only executes failed tasks, not successful tasks. For example, a Zap might have two actions: 1. Send an email, and 2. Add a spreadsheet row. If the Zap runs and successfully sends the email, but fails to add the spreadsheet row, replaying the task will only attempt to add the spreadsheet row again, not send the email again.


1. Manually replay failed tasks

If you're on a Starter plan or higher, you can manually replay any tasks that fail or were not successful.

  • Go to your Task History.
  • Here, you can filter tasks by status, Zap, or date, and select tasks to replay individually or in bulk.
    1. Individual: Select the checkboxes next to the tasks you want to replay.
    2. Bulk: In the upper left, click the checkbox dropdown menu and select Select shown to select all the tasks on the page, or Select all (5,000 at a time) to select up to 5,000 tasks.

If we wanted to replay 5,000 tasks at a time, we would open the menu and select "Select all (5,000 at a time)".

  • In the upper left, click Play [x].

After selecting tasks, we select Play to play the tasks.

  • In the upper right, the notifications menu will open to indicate that the tasks are replaying. Here, you can monitor the status of your task replay job. Once it completes, you'll see a summary of the results.

2. Turn on autoreplay for failed tasks

If you're on a Professional plan or higher and enable Autoreplay, Zapier will attempt to retry any tasks that fail due to temporary errors or downtime. Autoreplay will retry the action again immediately, and then a few more times if there is still an issue.

  • Go to your Task History.
  • In the upper right, click to toggle the Autoreplay switch ON.

Turn on autoreplay

How Autoreplay works

  • If a step in a task fails, Zapier will retry (replay) the task up to 5 times. While Autoreplay is engaged, no error emails will be sent, nor will any Zapier Manager Error Zaps be triggered during the Autoreplay window.
  • Zapier backs off after each successive failed retry attempt, on this schedule: 5 minutes, 30 minutes, 1 hour, 3 hours, 6 hours. This means that if the Zap errors at 1:00 PM, Autoreplay will try again at 1:05, 1:35, 2:35, 5:35, and 11:35. The back-off schedule implies the final retry happens ~10 hours, 35 minutes after the first error.
  • While Zapier is replaying a failed task (anywhere in that ~10-hour window), you cannot manually replay the task.
  • If you edit your Zap after the original error, any future Autoreplay attempts will consider those changes. This gives you the chance to tweak your Zap to help with preventable errors and let your Zap automatically ensure it gets sent correctly.
  • When Autoreplay attempts a retry, it checks the state of the Zap (this is how it considers Zap changes). If the Zap is off, or if Autoreplay itself has been switched off, the retry attempt will not run and all remaining retry attempts will be cancelled.
  • If you happen to turn your Zap off in between retries, it won't affect the retry schedule as long as the Zap is turned back on before the next retry attempt.
  • Tasks that are being replayed (or scheduled to be replayed) show up as "Scheduled" in your Task History.
  • While only errors can start Autoreplay, any subsequent non-"Success" steps will be replayed (which includes Halted, Errored, and Filtered) when that happens. Triggers typically do not error because we just try again anyway in a few minutes because of the way Zapier watches for triggers to happen.
  • If Zapier fails to replay the task after the last attempt (~10 hours later), we will send you an email indicating the error and trigger any Zapier Manager Zaps you might have. This is the first and only email about the error we send if you enable Autoreplay.

3. Troubleshoot tasks that can't be replayed

After attempting to replay tasks, you may find that some tasks couldn't be replayed. Zapier may not be able to replay a task due to any of the following:

  • The Zap is paused: turn on your Zap to replay these tasks.
  • The Zap has been deleted: tasks associated with a deleted Zap will not replay.
  • The Zap has changed too much: tasks associated with a Zap that has changed significantly will not replay.
  • The task is too old: tasks that are older than 2 months will not replay.
  • The task has already run successfully: tasks that have already run successfully will not replay.
  • The task is already scheduled to replay: tasks that are already scheduled to replay are will not replay.
