Summary

This document lists the runtime limits of the Function Platform (APL), including function writing limits, HttpAPI call limits, internal API call limits, execution time limits, memory limits, and other constraints. It helps developers design function logic properly and avoid triggering platform throttling.

Limit List

Category	Limit Category	Limit Value	Scope	Remarks
Function writing limits	Variable names that cannot be used in closures	owner; this; delegate	Network-wide	This limit applies in Range.each or list.foreach closures
External HttpAPI call limits from functions	Timeout limits	connectTimeout, default 2s; readTimeout, 5s, maximum 120s	Network-wide
	Retry count	connectTimeout, retries 3 times by default and can be changed by parameter; readTimeout, does not retry by default and can be changed by parameter; maximum retry count is 3 times for both types	Network-wide
	Maximum POST data size	5M	Network-wide
Internal API call limits from functions	Fx.object call count limit	300 (per function)	New enterprises
	Fx.object.editTeamMember, Fx.object.addTeamMember, Fx.object.addOutTeamMember, Fx.object.deleteTeamMember, Fx.object.changeOwner, Fx.object.batchChangeOwner	100 (per function)	Network-wide
	Fx.function call count limit	50 (per function)	New enterprises
	Fx.http	50 (per function)	New enterprises
	Fx.message	50 (per function)	New enterprises
	Fx.crm, Fx.work, Fx.file, Fx.AI, Fx.tag, Fx.approval	100 (per function)	New enterprises
Function execution limits	Execution limit for a single function on a single data record per unit time	Limited to 100 times per minute	Network-wide	An error is reported when the function execution count limit is exceeded
	Concurrent function executions for a single enterprise	Concurrent execution count is limited to 35	Network-wide
Scheduled task execution limits	Bound object - daily executed data row limit	Professional Edition: none; Flagship Edition: 100k; Unlimited Edition: 300k	Network-wide	Can be extended by purchasing resource packs separately
	Unbound object - daily execution duration limit	Professional Edition: none; Flagship Edition: half an hour; Unlimited Edition: 1.5 hours	Network-wide	Can be extended by purchasing resource packs separately
Execution time limits	New functions have runtime limits based on namespace	Button 20s Process 5min Custom controller 5min Scheduled task 10min E-signature 180s Authentication provider 180s Interconnected data synchronization 60s Validation function 50s Data integration 300s Event listener 5min ERP integration platform 180s Debug execution 120s Default for others 15s	All functions	See the execution time details table
Memory limits	The platform calculates memory usage throughout the entire execution process and limits memory information for a single function execution	Old functions: 512m; new functions: 256m	January 1, 2024 is the dividing line between old and new functions

New enterprises: Enterprises opened after February 4, 2021.

Background

The Function Platform (APL) has limits on function writing, API calls, execution time, memory usage, and other aspects to ensure stable platform operation and fair resource allocation. This document summarizes all known limits for developers to reference when designing function logic.

Notes

• Exceeding the execution count limit will cause a function execution error. It is recommended to add exception handling in code.
• Scheduled task limits differ across enterprise editions (Professional Edition/Flagship Edition/Unlimited Edition).
• The memory limits for old and new functions are divided by January 1, 2024.
• Higher quotas can be extended by purchasing resource packs separately.

Code Examples

// It is recommended to check the call count before calling an API to avoid triggering throttling
if (Fx.object.callCountThisMinute < 300) {
    def data = Fx.object.query("object_Test__c", [])
    // Process business logic normally
} else {
    // The call limit has been reached. Wait until the next minute before executing
    log.warn("The object API call count has reached the upper limit. Please try again later.")
}
