API call timeout 55 seconds API pagination is used to reduce API query timeout.
Call URL timeout Configured by the user Configured on the block with the Max automation execution time setting.
Custom code block maximum execution time 14,400 seconds (4 hours) -
Maximum API calls Rate limit of 300 calls per minute API calls include triggered automations.

Automation execution time

Platform limitations for automation execution time

Metric Limitation Notes
Maximum execution time for manual automation runs 4 hours This includes manual executions that are started as test runs, either from the automation editor or from the automation overview page.
Maximum execution time for triggered automation runs 55 seconds (async = false)
4 hours (async = true)
Maximum execution times for webhooks 15 minutes -

5 MB per block across all block executions
Maximum 200 list items.
State is truncated if limit exceeded.

Automation blocks

Platform limitations for specific automation blocks

Metric Limitation Notes
Custom code block Python, JavaScript, and PHP supported The custom code block does not support including libraries. See custom code block for more information.
Variable block Variables stored in memory To persist data or process large datasets, use a database or cloud storage.
