Service limits

General flow limits

The following table shows the limits that apply to the overall flow configuration and execution.

Name	Limit	Comments
Flow state maximum size	80 Megabits	Flow state: sum of all the inputs and outputs of a flow.
Maximum number of actions per flow	8 000 actions in five minutes per flow	If the limit is exceeded, the flow is disabled but it can be manually enabled after one minute. Note: This does not apply to Marketplace flows.

Iteration and loop limits

The following table shows the limits that apply to loops and iterations within flows.

Name	Limit	Comments
Maximum number of iterations using the For each action	1000	The limit of the number of iterations may vary according to the size of each iteration.
Maximum number of iterations in a liquid loop	10 000	This count includes all iterations, including nested loops. The flow will be stopped if the limit is reached.

Data size limits

The following table shows the limits that apply to data storage and input sizes.

Name	Limit	Comments
Parameters maximum number of characters	10 000 characters	Trying to input or reference data bigger than these limits will take only the first 10 000 characters.
Variables maximum size	25 KB	Trying to input or reference data bigger than these limits will take only the first 25 Kb.
Webhook maximum input size	25 Megabytes	If the input is bigger, 413 error (Request Entity Too Large) is returned.

Execution and timeout limits

The following table shows the limits that apply to action execution duration and timeouts.

Name	Limit	Comments
Action maximum duration	10 minutes / 5 retries	The maximum run time for an action is determined by the setup of two different variables on its Azure function: Timeout and maximum number of retries.
HTTP request maximum timeout	100 seconds

Note: The Unit4 Ava action is excluded since it is intended to manage asynchronous responses from an external service that needs it to hibernate until it is called again to continue the execution.

Communication limits

The following table shows the limits that apply to email and external communication actions.

Name	Limit	Comments
Email sender action limit per month	2 500 000 emails	The limit is shared within all the tenants of your region

Action-specific limits

The following sections show the limits that apply to specific actions and their unique constraints.

Run code action

The following table shows the limits that apply to the Run code action:

Limit	Value	Description
Maximum allowed depth of recursion	100	This means that recursive scripts will only be allowed to execute 100 levels of depth.
Script execution	600s (10 min)	Otherwise, the execution will fail with a timed-out result.
Maximum size allowed for arrays	10M elements
Maximum number of statements	500M	This includes variable declarations, conditional blocks, loops, function calls and such.
