This node throttles the workflow execution.


The Limiter plugin is used to control the rate at which the workflow executes. It allows you to set limits on the number of allowed executions within a defined time range. If the execution exceeds the specified limit, the plugin can either allow the execution to pass through or block it based on the configured parameters.

This documentation is based on version 0.7.3 of the Limiter plugin.

Inputs and Outputs


The Limiter plugin accepts the following input:

  • payload: This port takes a payload object as input.


The Limiter plugin provides the following outputs:

  • pass: Returns the input payload if the execution is not throttled.
  • block: Returns the input payload if the execution is throttled.


The Limiter plugin supports the following configuration parameters:

  • Number of allowed executions: Specify the number of allowed passes through this plugin within the defined time.
  • Time range (Time to live): Specify the time period (in seconds) that must pass for the limit to be reset to 0.
